	(3)  We have an investment policy approved by the Board of Directors that governs the quality, acceptability and dollar concentration of our investments.  The investment policy allows for investments in government and federal agency securities, commercial paper, repurchase agreements, bank certificates of deposit and money market funds.  Investments are comprised of marketable securities and consist primarily of commercial paper, asset-backed and mortgage-backed notes and bank certificates of deposits with original maturities beyond three months.  All marketable securities and corporate bonds are held in our name at two major financial institutions that hold custody of the investments.  All of our investments are held-to-maturity investments as we have the positive intent and ability to hold until maturity.  These securities are recorded at amortized cost.
	The amortized cost and unrealized gain or loss of our investments at September 30, 2013 and March 31, 2013 were:

Government Grants [Abstract]	'
Government Grants	'
	(7)   Government Grant
	We have a $45.1 million grant (the “Grant”) with the U.S. Department of Energy (“DOE”) under the American Recovery and Reinvestment Act. The Grant provides funds to facilitate the manufacture and deployment of electric drive vehicles, batteries and electric drive vehicle components in the United States. Pursuant to the terms of the Agreement, the DOE will reimburse us for 50 percent of qualifying costs for the purchase of facilities, tooling and manufacturing equipment, and for engineering related to product qualification and testing of our electric propulsion systems. The period of the Grant is through January 12, 2015. We recognize government grant reimbursements when it is probable that the Company will comply with the conditions attached to the grant arrangement and the grant money will be received.
	Funding for qualifying project costs incurred is currently limited to $32.0 million.  We were required to provide the DOE with an updated budget revision application by July 12, 2013, which we provided prior to the deadline. It is currently under review by the DOE.  If the DOE does not find the revision application acceptable, it reserves the right to: (1) stop payment on the contract; (2) renegotiate the contract; or (3) declare the grant terminated by mutual agreement after we have been given thirty days advance written notice and an opportunity to cure any deficiencies.
	The Grant is also subject to our compliance with certain reporting requirements. The American Recovery and Reinvestment Act imposes minimum construction wages and labor standards for projects funded by the Grant.
	If we dispose of assets acquired using Grant funding, we may be required to reimburse the DOE upon such sale date if the fair value of the asset on the date of disposition exceeds $5,000. The amount of any such reimbursement shall be equal to 50 percent of the fair value of the asset on the date of disposition.
	While UQM has exclusive patent ownership rights for any technology developed with Grant funds, we are required to grant the DOE a non-exclusive, non-transferable, paid-up license to use such technology.
	During the current quarter, we changed our cumulative estimate of reimbursable rates under the Grant which resulted in an increase in our reimbursement of costs recorded for the quarter and six month period of $817,000 and $958,000, respectively.  We expect our DOE reimbursements to return to approximate historical levels for the duration of the program. At September 30, 2013, we had received reimbursements from the DOE under the Grant totaling $21.2 million and had funds receivable under the Grant of $2.4 million.  Subsequent to the end of the quarter, the DOE paid $2.2 million against the funds receivable.
	The application of grant funds to the recorded value of eligible capital asset purchases under the Grant as of September 30, 2013 and March 31, 2013 are as follows:
		30-Sep-13
		Purchase Cost		Grant Funding		Recorded Value

Stock-Based Compensation	'
	(9)   Stock-Based Compensation
	Stock Option Plans
	As of September 30, 2013, we had 1,100,000 shares of common stock authorized and 10,031 shares of common stock available for future grant to employees and consultants under our 2012 Equity Incentive Plan (“Plan”).    The term of the 2012 Plan is ten years. Under the 2012 Plan, the exercise price of each option is set at the fair value of the common stock on the date of grant and the maximum term of the option is ten years from the date of grant. Options granted to employees generally vest ratably over a three-year period. The maximum number of options that may be granted to an employee under the Plan in any calendar year is 500,000 options. Forfeitures under the Plan are available for re-issuance at any time prior to expiration of the Plan in 2022. Options granted under the Plan to employees require the option holder to abide by certain Company policies, which restrict their ability to sell the underlying common stock. Prior to the adoption of the 2012 Plan, we issued stock options under our 2002 Equity Incentive Plan. Forfeitures under the 2002 Equity Incentive Plan may not be re-issued.
	Non-Employee Director Stock Option Plan
	In February 1994, our Board of Directors ratified a Stock Option Plan for Non-Employee Directors (“Directors Plan”) pursuant to which Directors may elect to receive stock options in lieu of cash compensation for their services as directors. As of September 30, 2013, we had 1,000,000 shares of common stock authorized and 184,798 shares of common stock available for future grant under the Directors Plan. Option terms range from three to ten years from the date of grant. Option exercise prices are equal to the fair value of the common shares on the date of grant. Options granted under the plan generally vest immediately. Forfeitures under the Directors Plan are available for re-issuance at a future date.
	Stock Purchase Plan
	We have established a Stock Purchase Plan under which eligible employees may contribute up to 10 percent of their compensation to purchase shares of our common stock at 85 percent of the fair market value at specified dates.  At September 30, 2013, we had 700,000 shares of common stock authorized and 336,041 shares of common stock available for issuance under the Stock Purchase Plan.  During the quarters and six month periods ended September 30, 2013 and 2012, we issued 28,618 and 141, and 34,030 and 26,836 shares of common stock, respectively, under the Stock Purchase Plan.  Cash received by us upon the purchase of shares under the Stock Purchase Plan for the quarters and six month periods ended September 30, 2013 and 2012 was $18,029 and $172, and $21,601 and $32,473, respectively.
	Stock Bonus Plan
	We have a Stock Bonus Plan (“Stock Plan”) administered by the Board of Directors. As of September 30, 2013, we had 1,954,994 shares of common stock authorized and there were 47,149 shares of common stock available for future grant under the Stock Plan.    Under the Stock Plan, shares of common stock may be granted to employees, key consultants, and directors who are not employees as additional compensation for services rendered. Vesting requirements for grants under the Stock Plan, if any, are determined by the Board of Directors at the time of grant. There were 441,195 and 440,934, and 452,195 and 440,934 shares granted to employees under the Stock Plan during the quarters and six month periods ended September 30, 2013 and 2012, respectively.
	We use the straight-line attribution method to recognize share-based compensation costs over the requisite service period of the award. Options granted by us generally expire ten years from the grant date. Options granted to existing and newly hired employees generally vest over a three-year period from the date of the grant. The exercise price of options is equal to the market price of our common stock (defined as the closing price reported by the NYSE MKT) on the date of grant.
	We use the Black-Scholes-Merton option pricing model for estimating the fair value of stock option awards. The expected volatility and the expected life of options granted are based on historical experience, and the risk free interest rate is obtained from the U.S. Department of the Treasury daily yield curve rates. The weighted average estimated values of employee and director stock option grants, as well as the weighted average assumptions that were used in calculating such values during the quarters and six month periods ended September 30, 2013 and 2012, were based on estimates at the date of grant as follows:
			Quarter Ended September 30,								Six Months Ended September 30,
			2013				2012				2013			2012
	Weighted average estimated
	fair value of grant		$	0.73			$	0.56			$	0.67		$	0.56
	Expected life (in years)			5.0				6.4				4.8			6.4
	Risk free interest rate			2.61	%			1.31	%			2.30	%		1.31	%
	Expected volatility			72.55	%			72.58	%			73.91	%		72.56	%
	Expected dividend yield			0.00	%			0.00	%			0.00	%		0.00	%
	The table below shows total share-based compensation expense for the quarters and six month periods ended September 30, 2013 and 2012 and the classification of these expenses:
			Quarter Ended September 30,						Six Months Ended September 30,
			2013			2012			2013			2012
	Costs of contract services		$	6,432		$	4,774		$	12,065		$	10,301
	Costs of product sales			9,963			11,089			20,318			21,836

			$	275,352		$	599,836		$	438,076		$	800,677
	Share-based compensation capitalized in inventories was insignificant as of September 30, 2013 and March 31, 2013.
	We adjust share-based compensation on a quarterly basis for changes to the estimate of expected equity award forfeitures based on actual forfeiture experience.  The effect of adjusting the forfeiture rate for all expense amortization is recognized in the period the forfeiture estimate is changed. The effect of forfeiture adjustments in the quarters and six month periods ended September 30, 2013 and 2012 were insignificant.
	All options/shares granted under the Non-Employee Director Stock Option Plan /Director’s Plan are fully vested.

	The Company currently has a full valuation allowance, as it is management’s judgment that it is more-likely-than-not that net deferred tax assets will not be realized to reduce future taxable income.
	We recognize interest and penalties related to uncertain tax positions in “Other Income,” net.  As of September 30, 2013 and 2012, we had no provisions for interest or penalties related to uncertain tax positions.

Loss Per Common Share	'
	(13) Loss Per Common Share
	Basic earnings per share is computed by dividing income or loss available to common stockholders by the weighted average number of common shares outstanding during the periods presented.  Diluted earnings per share is computed by dividing income or loss available to common stockholders by all outstanding and potentially dilutive shares during the periods presented, unless the effect is antidilutive.  At September 30, 2013 and 2012, respectively, common shares issued under the Stock Bonus Plan but not yet earned totaling 640,979 and 358,855 were being held by the Company.  For the quarters and six month periods ended September 30, 2013 and 2012 respectively, 99,492 and 32,681, and 38,354 and 47,430 shares, were potentially includable in the calculation of diluted loss per share under the treasury stock method but were not included, because to do so would be antidilutive.  At September 30, 2013 and 2012, options to purchase 3,721,309 and 4,590,325 shares of common stock, respectively, were outstanding.  For the quarters and six month periods ended September 30, 2013 and 2012, respectively, options for 2,222,706 and 3,181,758 and 2,312,548 and 3,156,758 shares were not included in the computation of diluted loss per share because the option exercise price was greater than the average market price of the common stock.  In-the-money options determined under the treasury stock method to acquire 490,432 and 163,541, and 289,701 and 224,330 shares of common stock for the quarters and six month periods ended September 30, 2013 and 2012, respectively, were potentially includable in the calculation of diluted loss per share but were not, because to do so would be antidilutive.

	Deferred compensation under executive employment agreements represents the future compensation potentially payable under the retirement and voluntary termination provisions of executive employment agreements.  The value of the Level 3 liability in the foregoing table was determined using a discounted cash flow model. The significant unobservable input used in the calculation is a discount rate of 14 percent, which is based on the expected cost of capital for the Company.  A 1 percent change in this discount rate would result in approximately a $1,000 change in the recorded value of the liability.
