POWER ELECTRONICS HANDBOOK
A typical high-voltage connector for an EV. Real-life use differs dramatically from conditions in derating tests where 1.4-m-long cables extend from either side of the connector.
Hot topic: Electric vehicle components get more sophisticated thermal models DR. MICHAEL LUDWIG, T&C CORE TECHNOLOGIES
The high electrical currents of fast charging are forcing designers to invent standard techniques for predictably modeling heat and cooling.
TE CONNECTIVITY
THE ONLY WAY electric vehicles (EVs) will ever catch on is if consumers can charge them up quickly. Consequently, manufacturers are developing high-power charging (HPC) schemes which would enable users to get 300 km of range in less than 10 minutes. The current generation of dc chargers work with 50 kW and 125 A in majority, but the next generation is expected to involve up to 350 kW. Simultaneously, designers of EVs are trying to boost range by reducing component weight and increasing efficiency. All of these changes will directly impact the design of the vehicle’s energy backbone.
