Testing challenges for EV powertrains: battery simulation and testing of V2G modules

Sponsored by ITECH

The deadline for banning the sale of internal combustion vehicles in various countries throughout the world has been announced one by one, and the completion of net-zero carbon emissions are rapidly approaching. It is critical to reduce reliance on fossil fuels as quickly as possible and promote electrification. As a result, governments have stepped up to promote the electric vehicle industry. However, the industry’s new designs and innovations bring new testing challenges too.

Electric vehicles contain approximately three times the number of power electronic components as gasoline vehicles, according to research. It usually has high-voltage and high-power characteristics. How can these components be efficiently tested and the electric propulsion system’s dynamic performance verified? Engineers require thorough and competent solutions.

Compared to typical gasoline vehicles, the EV Powertrain System is primarily made up of a power battery system, a drive motor, and a vehicle controller. Gasoline automobiles, in essence, turn chemical energy into mechanical energy, whereas electric vehicle powertrains transfer electrical energy into mechanical energy. Because of the distinct operating principles, troubleshooting the power system of pure EV is wholly new and continually evolving. The debugging job mainly includes low-voltage system debugging, power-on and power-off debugging, high-voltage system joint debugging, charging debugging, and so on. The difficulties encountered in this procedure include, on the one hand, high-voltage and high-current wiring, as well as operational safety issues; on the other hand, if you use a real battery for testing, there are risks such as poor efficiency and battery explosion. As a result, using a high-performance battery simulator for testing is a good decision.

ITECH Electronics provides comprehensive testing solutions for EV powertrain system. The IT6000C bidirectional DC power supply equipped with the battery simulation software BSS2000 can fully meet the requirement of various testing applications. It has the advantages such as fast switching between battery charging and discharging, wide range of power combination, built-in most kinds of battery characteristic curves and so on. It can largely save cost and time for your testing job. In addition, ITECH IT7900 regenerative grid simulator can perform the testing for V2G modules which cater the bidirectional EV technology trend in the future.
