Isolation technologies for EV power electronics

A previous article on bidirectional chargers touched on using transformers to provide isolation at high power levels—in which application they are the only game in town, really—but this time the focus will be on achieving isolation at low power levels, such as the feedback signal in a regulator, data communication buses between devices, gate drivers… Read more »

Setting a new standard for battery leak testing

Defective cells can shorten battery life, decrease range, and lead to safety issues. A leaky cell housing, one common failure mode for Li-ion batteries, can allow ambient humidity to come in contact with the electrolyte, triggering an exothermic (heat-releasing) chemical reaction.  Currently, the common practice in the battery manufacturing industry is to test cell packaging… Read more »

2020 EV Charging Infrastructure Best-in-Test: Rating the DC fast charging user experience

If EVs are to replace fossil-fuel vehicles, they need to be able to make long highway trips, which means that DC fast charging needs to be reliable, convenient, affordable and ubiquitous. However, as Charged and other media have often reported, we’re still in the early days of public EV charging, and the user experience often… Read more »
