Switcher steps in with 12 V supply

Power Integrations has unveiled a flyback switcher with an integrated 750 V MOSFET and secondary-side sensing that can be used to provide an alternative 12 V power supply for an EV if its onboard 12 V battery fails (writes Nick Flaherty). The InnoSwitch3-AQ can be used for traction inverters, onboard charger, DCDC bus converters and BMSs. The 12 V battery is used to provide the gate drive...

Fast-charge ferries start sea trials

A fleet of fully electric passenger ferries is rolling out in Thailand using motors from Danfoss Editron (writes Nick Flaherty). The first two 24 m-long catamarans are currently being tested in Bangkok. Each one is fitted with two Danfoss EMPMI375-T800 motors. The motors use synchronous reluctance assisted...

Tesla cars to use structural cells

Electric car maker Tesla is to use a new form factor for its battery cells that will form part of the structure of its vehicles (writes Nick Flaherty). The company is also using a new material, silicon powder, and a new roll-to-roll manufacturing process to build the cells. In the current 2170 cell, which is 21 mm in diameter and 70 mm long, the roll of electrodes...

Battery chip boosts EV range

A sensing and balancing chip for battery packs that can extend the range and reliability of EVs has been launched (writes Nick Flaherty). The TLE9012AQU from Infineon Technologies supports up to 12 battery cells with an accuracy of ±5.8 mV over a pack’s temperature and voltage range as well as its life cycle. This accuracy extends an EV’s range...

ATMP goes electric

Researchers at the University of Exeter, in the UK, have teamed up with Supacat to develop an electric version of the 6 x 6 All-Terrain Mobility Platform, or ATMP (writes Nick Flaherty). The ATMP, first developed in the 1980s, already operates in a range of harsh terrains for military applications using a diesel engine. The conversion to an electric powertrain had to be rugged...

Relay device retains memory

Researchers at the University of Bristol, in the UK, have developed a new type of electromechanical nanodevice that can be used as a non-volatile memory in high-temperature power systems in EVs and aircraft (writes Nick Flaherty). The leakage current in transistors used as electronic memory devices increases with temperature, so an electromechanical relay built on a micromachined...
