 ACE Batteries Drive LFP Technology Closer to Li-ion for EVs

How the prismatic cells fit directly into the battery pack

When modern EVs were introduced, the main reason for their initial slow sales was the range. However, battery technology has progressed and now some of the latest vehicles can get almost 600 miles on a full charge. As always in engineering, when one problem is solved another crops up, or in the case of electric veh

Diving into the Dog Days of Summer with EVs

Jason Lomberg, North American Editor, PSD

­Last month, I mentioned a two-issue string of interrelated topics, starting with July’s “Batteries and Other Storage Devices” and leading straight into the application most relevant to these miniature power sources, electric vehicles. After all, the priciest component of EVs is the battery pack, and

Recharging the Batteries and the March Towards Electric Vehicles

Ally Winning, European Editor, PSD

­It’s nice and sunny here in Scotland as I write this, a welcome change from the weather of the last few weeks. We are well and truly into the holiday season and it is good to take some time out. Myself, I had a short visit to one of the Scottish islands. The islands are often quite behind the times when it

How to Increase High-Power EV Battery Charging using Surface Mount Power Devices

How to Increase High-Power EV Battery Charging using Surface Mount Power Devices

­End users expect new EV designs to minimize vehicle idle time, especially for long-distance driving. EV automotive designers need to increase charger power output, power density, and efficiency to achieve the fast-charging end-users expect. Single-unit, charger designs currently range from 7 kW to 30 kW. The co
