| 1.
I have reviewed this annual report on Form      10-K of UQM Technologies, Inc.;
2.
Based on my knowledge, this Report does not      contain any untrue statement of material fact or omit to state a material      fact necessary to make the statements made, in light of the circumstances      under which such statements were made, not misleading with respect to the      period covered by this Report;
3.
Based on my knowledge, the financial      statements, and other financial information included in this Report,      fairly present in all material respects the financial condition, results      of operations and cash flows of the registrant as of, and for, the periods      presented in this Report;
4.
The registrant's other certifying officer      and I are responsible for establishing and maintaining disclosure controls      and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e))      and internal control over financial reporting (as defined in Exchange Act      Rules 13a-15(f) and 15d-15(f)) for the registrant and we have:

a. 
Designed such disclosure controls and      procedures, or caused such disclosure controls and procedures to be      designed under our supervision, to ensure that material information      relating to the registrant, including its consolidated subsidiaries, is      made known to us by others within those entities, particularly during the      period in which this Report is being prepared;
b.
Designed such internal control over financial      reporting, or caused such internal control over financial reporting to be      designed under our supervision, to provide reasonable assurance regarding      the reliability of financial reporting and the preparation of financial      statements for external purposes in accordance with generally accepted      accounting principles;
c.
Evaluated the effectiveness of the registrant's      disclosure controls and procedures and presented in this Report our      conclusions about the effectiveness of the disclosure controls and      procedures, as of the end of the period covered by this Report based on      such evaluation; and
d.
Disclosed in this Report any change in the      registrant's internal control over financial reporting that occurred      during the registrant's most recent fiscal quarter (the registrant's      fourth fiscal quarter in the case of an annual report) that has materially      affected, or is reasonably likely to materially affect, the registrant's      internal control over financial reporting; and
5. 
The registrant's other certifying officer      and I have disclosed, based on our most recent evaluation of internal      control over financial reporting, to the registrant's auditors and the      audit committee of the registrant's board of directors (or persons      performing the equivalent functions):
a.
All significant deficiencies and material      weaknesses in the design or operation of internal control over financial      reporting which are reasonably likely to adversely affect the registrant's      ability to record, process, summarize and report financial information;      and
b.
Any fraud, whether or not material, that      involves management or other employees who have a significant role in the      registrant's internal controls over financial reporting.
