("Highpower") and its subsidiaries, Hong Kong Highpower Technology Company Limited ("HKHTC"), Shenzhen Highpower Technology Company Limited ("SZ Highpower"), Springpower Technology (Shenzhen) Company Limited ("SZ Springpower"), Ganzhou Highpower Technology Company Limited ("GZ Highpower"), Icon Energy System Company Limited ("ICON") and Huizhou Highpower Technology Company Limited (“HZ HTC”).

Summary of significant accounting policies [Abstract]
Significant Accounting Policies [Text Block]	2. Summary of significant accounting policies The Company has reclassified certain comparative balances in the consolidated balance sheet for December 31, 2015 to conform to the current period’s presentation. The reclassification is related to the aggregation of the balance of prepayments and the balance of other receivables into the balance of prepayments and other receivables. The reclassification did not have an impact on the reported total assets, liabilities and stockholders’ equity. No customer accounted for 10% or more of total sales during the three and nine months ended September 30, 2016 and 2015. No supplier accounted for 10% or more of the total purchase amount during the three and nine months ended September 30, 2016 and 2015. No customer accounted for 10% or more of the accounts receivable as of September 30, 2016. As of December 31, 2015, there was one major customer accounted for 11.3 Investments in equity securities of privately-held companies in which the Company holds less than 20% voting interest are accounted for under the cost method. Investments in equity securities of privately-held companies in which the Company has between 20% and 50% of ownership interest in the voting stock, and to which the Company does not have the ability to exercise significant influence are accounted for under the cost method. Significant influence is generally considered to exist when the Company has between 20% and 50% of ownership interest in the voting stock, but other factors, such as representation on the board of directors, voting rights and the impact of commercial arrangements, are considered in determining whether the equity method of accounting is appropriate. Entities in which the Company has the ability to exercise significant influence, but does not have a controlling interest, are accounted for under the equity method. The Company evaluates potential impairment whenever events or changes in circumstances indicate that the carrying amount of the investments may not be recoverable. For investments carried at cost, the Company recognizes impairment in the event that the carrying value of the investment exceeds the Company’s proportionate share of the net book value of the investee. As of September 30, 2016, management believes no impairment charge is necessary. Highpower’s functional currency is the United States dollar ("US$"). HKHTC's functional currency is the Hong Kong dollar ("HK$"). The functional currency of the Company’s subsidiaries in the PRC is the Renminbi ("RMB"). Most of the Company’s oversea sales are priced and settled with US$. At the date a foreign currency transaction is recognized, each asset, liability, revenue, expense, gain, or loss arising from the transaction is measured initially in the functional currency of the recording entity by use of the exchange rate in effect at that date. The increase or decrease in expected functional currency cash flows upon settlement of a transaction resulting from a change in exchange rates between the functional currency and the currency in which the transaction is denominated is recognized as foreign currency transaction gain or loss that is included in determining net income for the period in which the exchange rate changes. At each balance sheet date, recorded balances that are denominated in a foreign currency are adjusted to reflect the current exchange rate. The Company’s reporting currency is US$. Assets and liabilities of HKHTC and the PRC subsidiaries are translated at the current exchange rate at the balance sheet dates, revenues and expenses are translated at the average exchange rates during the reporting periods, and equity accounts are translated at historical rates. Translation adjustments are reported in other comprehensive income. In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers, or ASU 2014-09. This new standard will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to correlate with the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB voted to defer the effective date of ASU 2014-09 by one year, while allowing a company to adopt the new revenue standard early but not before the original effective date. This guidance will be effective as to us on January 1, 2018 and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. In April and May 2016, the FASB issued Accounting Standards Update 2016-10, Revenue from Contracts with Customers, or ASU 2016-10, and Accounting Standards Update 2016-12, Revenue from Contracts with Customers, or ASU 2016-12, respectively. These new standards will identify performance obligations and narrow aspects on achieving core principle. The Company is currently evaluating the impact of adopting these ASUs on our consolidated financial statements. On February 25, 2016, the FASB issued Accounting Standards Update (ASU) 2016-02, Leases (Topic 842). It requires that a lessee recognize the assets and liabilities that arise from operating leases. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. Public business entities should apply the amendments in ASU 2016-02 for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years (i.e., January 1, 2019, for a calendar year entity). Early application is permitted for all public business entities and all nonpublic business entities upon issuance. The Company is currently evaluating the impact of adopting ASU 2016-02 on our consolidated financial statements. In March 2016, the FASB issued Accounting Standards Update (ASU) 2016-07, Investments-Equity Method and Joint Venture (Topic 323). The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. It is effective for all entities for the fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Earlier application is permitted. The Company did not earlier adopt ASU 2016-07 on our consolidated financial statement. In August 2016, the FASB issued Accounting Standards Update (ASU) 2016-15, Statement of Cash Flows (Topic 230). The amendments in this Update provide guidance on eight specific cash flow issue. It applies to all entities. For public business entities, the amendments in this Update are effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual period. The Company is currently evaluating the impact of adopting ASU 2016-09 on our consolidated financial statements. In October 2016, the FASB issued Accounting Standards Update (ASU) 2016-16, Income Taxes (Topic 740). The amendments in this Update is to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory and align the recognition of income tax consequences for intra-entity transfers of assets other than inventory with International Financial Reporting Standards (IFRS). Public business entities should apply the amendments in ASU 2016-16 for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted for any entity in any interim or annual period. The Company is currently evaluating the impact of adopting ASU 2016-16 on our consolidated financial statements. We do not believe other recently issued but not yet effective accounting standards, if currently adopted, would have a material effect on the consolidated financial position, statements of operations and cash flows.

Summary of significant accounting policies [Abstract]
Consolidation, Policy [Policy Text Block]	Reclassification The Company has reclassified certain comparative balances in the consolidated balance sheet for December 31, 2015 to conform to the current period’s presentation. The reclassification is related to the aggregation of the balance of prepayments and the balance of other receivables into the balance of prepayments and other receivables. The reclassification did not have an impact on the reported total assets, liabilities and stockholders’ equity.
Concentration Risk, Credit Risk, Policy [Policy Text Block]	Concentrations of credit risk No customer accounted for 10% or more of total sales during the three and nine months ended September 30, 2016 and 2015. No supplier accounted for 10% or more of the total purchase amount during the three and nine months ended September 30, 2016 and 2015. No customer accounted for 10% or more of the accounts receivable as of September 30, 2016. As of December 31, 2015, there was one major customer accounted for 11.3
Investment, Policy [Policy Text Block]	Long-term investment Investments in equity securities of privately-held companies in which the Company holds less than 20% voting interest are accounted for under the cost method. Investments in equity securities of privately-held companies in which the Company has between 20% and 50% of ownership interest in the voting stock, and to which the Company does not have the ability to exercise significant influence are accounted for under the cost method. Significant influence is generally considered to exist when the Company has between 20% and 50% of ownership interest in the voting stock, but other factors, such as representation on the board of directors, voting rights and the impact of commercial arrangements, are considered in determining whether the equity method of accounting is appropriate. Entities in which the Company has the ability to exercise significant influence, but does not have a controlling interest, are accounted for under the equity method. The Company evaluates potential impairment whenever events or changes in circumstances indicate that the carrying amount of the investments may not be recoverable. For investments carried at cost, the Company recognizes impairment in the event that the carrying value of the investment exceeds the Company’s proportionate share of the net book value of the investee. As of September 30, 2016, management believes no impairment charge is necessary.
Foreign Currency Transactions and Translations Policy [Policy Text Block]	Foreign currency translation and transactions Highpower’s functional currency is the United States dollar ("US$"). HKHTC's functional currency is the Hong Kong dollar ("HK$"). The functional currency of the Company’s subsidiaries in the PRC is the Renminbi ("RMB"). Most of the Company’s oversea sales are priced and settled with US$. At the date a foreign currency transaction is recognized, each asset, liability, revenue, expense, gain, or loss arising from the transaction is measured initially in the functional currency of the recording entity by use of the exchange rate in effect at that date. The increase or decrease in expected functional currency cash flows upon settlement of a transaction resulting from a change in exchange rates between the functional currency and the currency in which the transaction is denominated is recognized as foreign currency transaction gain or loss that is included in determining net income for the period in which the exchange rate changes. At each balance sheet date, recorded balances that are denominated in a foreign currency are adjusted to reflect the current exchange rate. The Company’s reporting currency is US$. Assets and liabilities of HKHTC and the PRC subsidiaries are translated at the current exchange rate at the balance sheet dates, revenues and expenses are translated at the average exchange rates during the reporting periods, and equity accounts are translated at historical rates. Translation adjustments are reported in other comprehensive income.
New Accounting Pronouncements, Policy [Policy Text Block]	Recently issued accounting pronouncements In May 2014, the FASB issued Accounting Standards Update 2014-09, Revenue from Contracts with Customers, or ASU 2014-09. This new standard will replace all current U.S. GAAP guidance on this topic and eliminate all industry-specific guidance. The new revenue recognition standard provides a unified model to determine when and how revenue is recognized. The core principle is that a company should recognize revenue to correlate with the transfer of promised goods or services to customers in an amount that reflects the consideration for which the entity expects to be entitled in exchange for those goods or services. In July 2015, the FASB voted to defer the effective date of ASU 2014-09 by one year, while allowing a company to adopt the new revenue standard early but not before the original effective date. This guidance will be effective as to us on January 1, 2018 and can be applied either retrospectively to each period presented or as a cumulative-effect adjustment as of the date of adoption. In April and May 2016, the FASB issued Accounting Standards Update 2016-10, Revenue from Contracts with Customers, or ASU 2016-10, and Accounting Standards Update 2016-12, Revenue from Contracts with Customers, or ASU 2016-12, respectively. These new standards will identify performance obligations and narrow aspects on achieving core principle. The Company is currently evaluating the impact of adopting these ASUs on our consolidated financial statements. On February 25, 2016, the FASB issued Accounting Standards Update (ASU) 2016-02, Leases (Topic 842). It requires that a lessee recognize the assets and liabilities that arise from operating leases. A lessee should recognize in the statement of financial position a liability to make lease payments (the lease liability) and a right-of-use asset representing its right to use the underlying asset for the lease term. For leases with a term of 12 months or less, a lessee is permitted to make an accounting policy election by class of underlying asset not to recognize lease assets and lease liabilities. In transition, lessees and lessors are required to recognize and measure leases at the beginning of the earliest period presented using a modified retrospective approach. Public business entities should apply the amendments in ASU 2016-02 for fiscal years beginning after December 15, 2018, including interim periods within those fiscal years (i.e., January 1, 2019, for a calendar year entity). Early application is permitted for all public business entities and all nonpublic business entities upon issuance. The Company is currently evaluating the impact of adopting ASU 2016-02 on our consolidated financial statements. In March 2016, the FASB issued Accounting Standards Update (ASU) 2016-07, Investments-Equity Method and Joint Venture (Topic 323). The amendments require that the equity method investor add the cost of acquiring the additional interest in the investee to the current basis of the investor’s previously held interest and adopt the equity method of accounting as of the date the investment becomes qualified for equity method accounting. It is effective for all entities for the fiscal years, and interim periods within those fiscal years, beginning after December 15, 2016. Earlier application is permitted. The Company did not earlier adopt ASU 2016-07 on our consolidated financial statement. In August 2016, the FASB issued Accounting Standards Update (ASU) 2016-15, Statement of Cash Flows (Topic 230). The amendments in this Update provide guidance on eight specific cash flow issue. It applies to all entities. For public business entities, the amendments in this Update are effective for annual periods beginning after December 15, 2017, and interim periods within those annual periods. Early adoption is permitted for any entity in any interim or annual period. The Company is currently evaluating the impact of adopting ASU 2016-09 on our consolidated financial statements. In October 2016, the FASB issued Accounting Standards Update (ASU) 2016-16, Income Taxes (Topic 740). The amendments in this Update is to improve the accounting for the income tax consequences of intra-entity transfers of assets other than inventory and align the recognition of income tax consequences for intra-entity transfers of assets other than inventory with International Financial Reporting Standards (IFRS). Public business entities should apply the amendments in ASU 2016-16 for fiscal years beginning after December 15, 2017, including interim periods within those fiscal years. Early adoption is permitted for any entity in any interim or annual period. The Company is currently evaluating the impact of adopting ASU 2016-16 on our consolidated financial statements. We do not believe other recently issued but not yet effective accounting standards, if currently adopted, would have a material effect on the consolidated financial position, statements of operations and cash flows.
