Test post

In September, an international task force including representatives of the National Renewable Energy Laboratory (NREL) and the Charging Interface Initiative (CharIN) hosted a meeting of “leading OEMs, utilities, equipment manufacturers and suppliers” to test prototypes for a new charging system for heavy-duty vehicles: the Megawatt Charging System (MCS). The task force says the test, which… Read more »

EV motor shaft bearings: One of the few moving parts

CoorsTek argues that ceramic bearings are the best fit for EVs The less moving parts in a machine, the better. That’s one often-heard argument for the superiority of electric powertrains over internal combustion engines (ICEs), in which the number of moving components is dramatic. Sure, EVs have a lot of electrons moving this way and… Read more »

EMC for EVs: Understanding electromagnetic compatibility

Engineers who design power electronics supplied by the mains have had to contend with meeting various electrical noise and safety standards for decades now, but their counterparts in the automotive industry were mostly free to do as they pleased. This was mainly because 12 V isn’t considered a shock hazard and cars are effectively rolling… Read more »

BRUGG eConnect to launch 850-amp liquid-cooled charging cable

Swiss cable maker BRUGG eConnect has announced a new high-performance charging cable, the PURWIL Connect 850+ Cooled, that can deliver DC electricity at 1,000 volts and up to 850 amps. The company plans to launch the cable in early 2020. Today’s conventional cables typically max out at 550 amps, but thanks to an in-wire cooling system, the PURWIL Connect… Read more »

A closer look at advances in power PCBs

In just the last few years there have been some major improvements in printed circuit board technology that are especially relevant to power electronics. Arguably the most important of the recent advances is the development of new board substrates that can withstand higher temperatures, along with metal cores for improved heat transfer, and the ability… Read more »

Cable sizing and selection for EV systems

Why Champlain Cable backs irradiation cross-linking for high-voltage EV cable insulation When you think of what makes up an EV, cables and wires probably aren’t the first components that come to mind. But these conduits comprise the electrical cardiovascular system that makes a vehicle function – from the battery to the motor and all the… Read more »

MAHLE’s new battery housing delivers same power from 40% smaller batteries

MAHLE has developed a new battery housing concept with integrated thermal management designed to increase rapid charging capability and vehicle range. MAHLE claims the new housing allows manufacturers to use batteries that are about 40% smaller, which not only reduces the CO2 footprint of the EV, but also lowers the demand for raw battery materials….
