Sponsored by Littelfuse EV charging stations come in many different types and provide differing speeds (or levels) of charge to a vehicle. Most chargers can be classified into one of two types: AC chargers, which provide alternating current (AC) power to a vehicle’s on-board charger from an electrical utility supply DC chargers, which provide direct… Read more »

A closer look at DC-DC converters
As far as we know, all EVs in production by major automakers use a conventional lead-acid battery for the 12 V system (surprising, but true – more on why in a bit) and this battery needs charging, just as it does in an ICE vehicle. While you could hang an alternator off the traction motor… Read more »
Wire bonding for EV batteries and inverters: application and process tips from Hesse Mechatronics
Sponsored by Hesse Mechatronics All electronic devices need to be connected electrically (and mechanically) and there are numerous ways of completing this task. Wire bonding is one type of interconnection. There are three types of wire bonding: thermocompression, thermosonic and ultrasonic. We will focus on ultrasonic wedge bonding with aluminium wire and discuss the wire bonding process… Read more »
