Update: SAE International recommended practice for electric and hybrid electric vehicle safe battery testingEngineering360 News Desk | August 26, 2021
SAE International has issued a revised recommended practice for establishing safe battery systems for hybrid electric vehicles (HEVs) and electric vehicles (EVs).
HEVs and EVs depend on rechargeable energy storage devices such as batteries and capacitors to realize the benefits of improved performance and fuel economy. Safety of advanced energy storage devices needs to be demonstrated and accepted by original equipment manufacturers to commercialize advanced high energy batteries in HEVs and EVs. Widespread use and adoption of SAE J2464: Electric and Hybrid Electric Vehicle Rechargeable Energy Storage System (RESS) Safety and Abuse Testing will advance that goal.
The J2464 recommended practice describes a body of tests that can be used as needed for abuse testing of EV or HEV RESS to determine the response of the electrical energy storage and control systems to conditions or events that are beyond their normal operating range.
Abuse test procedures in the document are intended to cover a broad range of vehicle applications as well as a broad range of electrical energy storage devices, including individual RESS cells (batteries or capacitors), modules and packs. The document specifically applies to vehicles with RESS voltages above 60 V and does not apply to RESS that uses mechanical devices to store energy, such as electro-mechanical flywheels.
