Embodiment Construction

[0034]As discussed in the background section, battery packs used with electric vehicles are able to store large amounts of energy. The battery packs are large and difficult to work on and test because of the high voltages involved. Further, the battery packs are expensive. In one aspect, the present application recognizes that a single bad battery within the battery pack can reduce the capabilities of the overall battery pack. A bad battery or (batteries) can reduce the amount of energy the battery pack can store, reduce the rate at which the battery pack can be recharged and cause other batteries with in the battery pack to drain prematurely.

[0035]In one aspect of the present invention, a battery pack is removed from the electric vehicle whereby maintenance can be performed on it. More specifically, individual batteries of the pack tested. A refurbished battery pack is made by preparing a new set of batteries for use in creating a refurbished battery pack. The new set of batteries ...

Abstract

A method and apparatus for repairing or testing a used battery pack from an electric vehicle include removing the battery pack from the vehicle. Battery tests are performed on at least some of the plurality of batteries and battery test results for each of the batteries tested are obtained. A cradle is configured to receive at least two different types of batteries. The cradle includes connectors to electrically couple circuitry of a battery tester to the battery.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]The present application is based on and claims the benefit of U.S. provisional patent application Ser. No. 61 / 351,017, filed Jun. 3, 2010, and the present application is also a Continuation of and claims priority of U.S. patent application Ser. No. 12 / 894,951, filed Sep. 30, 2010, the content of which is hereby incorporated by reference in its entirety.BACKGROUND OF THE INVENTION[0002]The present invention relates to electric vehicles of the types which use battery packs for storing electricity. More specifically, the present invention relates to maintenance of such battery packs.[0003]Traditionally, automotive vehicles have used internal combustion engines as their power source. Petroleum as a source of power. However, vehicles which also store energy in batteries are finding widespread use. Such vehicle can provide increased fuel efficiency and can be operated using alternative energy sources.[0004]Some types of electric vehicles are com...
