Motor cooling

E-motor cooling technology is evolving rapidly, as Peter Donaldson finds out Discussions on thermal management in electric vehicles (EVs) usually focus on the battery because of the risk and potential consequences of thermal runaway. However, keeping motors comfortable in terms of temperature is also crucial to the performance, reliability, efficiency and longevity of an EV’s powertrain

Busbar connector alternative to electroplating

Penn Engineering has developed a new technique to reduce the cost of busbar connections in electric vehicles, writes Nick Flaherty. “The challenge is how to connect busbars,” says John O’Brien, global technologist at Penn Engineering. “One of the things we have seen is a move from cabling to busbars, driven by cost. Busbars are much cheaper for the same current than cables and more suited for automated assembly, which also gives lower cost.”

Motor testing

Peter Donaldson examines various means of testing electric motors. Although mechanically simple, compared with internal combustion engines, the electric motors forming the heart of the propulsion system of EVs of all kinds must go through intensive testing. This involves the use of many technologies and procedures to probe performance, efficiency, reliability and safety at every stage of manufacture and integration.
