Battery Testing of Electric Vehicles (EV)

Lithium-Ion batteries are the most common traction batteries used in electric vehicle (EV).  Global standardisation agencies such as IEC, ISO, SAE have defined set of test standards for each of the following functional parameter of Li-ion batteries.
a. Energy
b. Capacity
c. Power
d. Internal Resistance
e. Charge Retention
f. Cranking Power at low & high temperatures
g. Energy Efficiency
h. Cycle life of Li-ion batteries

Environmental impact on EV and its traction batteries are crucial in determining the product reliability and performance adherence. In addition to the test standards specified by IEC, ISO, UL, SAE, there are also country-specific test standards which an EV supplier or manufacturer must comply. For instance, China follows a series of test standards under QC/T743:2006, while India follows BIS 13514:1992 for lead-acid batteries. South Korea supports ISO 12405-1 and KS C IEC 62660-1. The international body called UNECE World Forum for Harmonization of Vehicle Regulations has published Electric Vehicle Regulatory Guide. This guide act as a single point of reference for environmentally-related EV requirements.

Following are the list of environment tests to be conducted on EV & its Li-ion batteries using the Environmental Test Chamber.
