The state of health of cells in a battery pack under operating condition is difficult to obtain through existing IEC and ISO standard methods under laboratory conditions. However, a cell state of health (SOH) profile shall be able to establish by the comparison of electro-impedance spectroscopy (EIS) generated statically versus dynamic operating data retrieved by battery management system (BMS) communication interface as fragments of EIS.

Low-frequency magnetic fields, a type of electromagnetic disturbance commonly found in electric vehicles, can pose potential health hazards to humans and affect the operation of critical EV components. Here are some design techniques to help mitigate the problem.

EV batteries and battery packs are complex systems, requiring a comprehensive design and testing strategy to help ensure safe and efficient electrical power.

DC-DC converters are among the most important modules in an electric vehicle. In this article, we offer three recommendations to address design aspects of DC-DC converters that will make a huge difference in their EMC performance.

A group of international researchers has reportedly developed a new formula for solder that...

This article presents the EMC design techniques for electric vehicle powertrain modules. High voltage EMC regulations for powertrain modules are reviewed first to help understand associated design challenges. The design techniques are then demonstrated in detail to help engineers design a module that will pass the EMC requirements in the test chamber.
