Can the global battery supply chain keep up with anticipated EV demand?

Posted by & filed under Newswire, The Tech.

As global demand for EVs increases, many are questioning the adequacy of the existing battery supply chain. A recent article in Transport Dive discusses the challenges involved in building a global supply chain that can keep up with the anticipated growth in EV production. Elon Musk said in October that a shortage of battery cells… Read more »

The technical challenges of bidirectional chargers

Posted by & filed under Features, Fleets and Infrastructure Features, Tech Features.

For years, we’ve been hearing about an EV technology that promises to be a game-changer: Vehicle-to-Grid (V2G) bidirectional charging. My recent work with one V2G charger developer, Fermata Energy, has convinced me that V2G has found its proverbial killer app: load peak shaving for commercial/industrial energy customers. This article is going to concentrate on the… Read more »

ABB to supply EVSE for Norwegian grocery wholesaler’s electric fleet

Posted by & filed under Fleets and Infrastructure, Newswire, The Infrastructure.

ABB has agreed to supply charging infrastructure for Norwegian grocery wholesaler ASKO’s growing fleet of electric trucks. ASKO operates a fleet of 600 trucks, and hopes to achieve zero-emission distribution of groceries by 2026. ABB will provide charging infrastructure for ASKO’s distribution centers throughout Norway. The first ABB HVC 150C (150 kW) chargers are already… Read more »

EMC for EVs: Understanding electromagnetic compatibility

Posted by & filed under Features, Fleets and Infrastructure Features, Tech Features.

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 »

Why did Porsche go to the trouble of designing an 800 V Taycan EV?

Posted by & filed under Newswire, The Tech.

How higher-voltage battery packs enable faster charging ecosystems Porsche took on a considerable engineering challenge when it decided to design an 800 V EV system for the Taycan, because nearly every other hybrid and EV in the world operates at 400 V or less. There simply was not a wide range of high-voltage off-the-shelf parts… Read more »

A closer look at current sensors in EVs

Posted by & filed under Features, Fleets and Infrastructure Features, Tech Features.

Pretty much every electronic circuit that handles significant power utilizes some means of measuring current, whether to simply protect against overload or because it is a basic functional requirement. In this article we’ll cover some of the more common devices and circuit techniques for measuring current in the major subsystems of an EV, including when… Read more »
