What is an electric energy storage abuse test?

This manual defines a complete body of abuse tests intended to simulate actual use and abuse conditions that may be beyond the normal safe operating limits experienced by electrical energy storage systems used in electric and hybrid electric vehicles.

What is the FreedomCAR energy storage manual?

This manual was prepared by and for the FreedomCAR Program Electrochemical Energy Storage Team. It is based on the goals established for FreedomCAR energy storage development and is similar (with some important changes) to an earlier manual for the former Partnership for a New Generation of Vehicles (PNGV) program.

What is an electric energy storage test?

The tests described are intended for abuse testing any electrical energy storage system designed for use in electric or hybrid electric vehicle applications whether it is composed of batteries, capacitors, or a combination of the two.

What are the goals of the FreedomCAR program?

The FreedomCAR program defines a number of goals for battery performance over life. (See Table 1 in the body of this manual.) Power and energy capability are evaluated using the HPPC test, while round-trip efficiency and cycle life are evaluated using special pulse profile tests for either Minimum Power Assist or Maximum Power Assist operation.

What is an electric vehicle (EV) abuse test?

A road vehicle that uses stored electrical energy as its source of energy for motive (traction) power. EVs are generally charged with AC power provided by an electric utility and are on stationary charge between uses. A type of abuse test that would, in general, be considered highly unlikely to occur during ‘normal’ vehicle operation.

What is a FreedomCAR cycle life test?

FreedomCAR cycle life test procedures in this manual are intended for cycling at fixed values of state-of-charge (SOC), defined on the basis of a fractional depth-of-discharge (DOD, i.e., percent of rated capacity in Ah) from a fully charged state.
