Public charging networks have been coming in for their share of criticism lately. Recent studies from UC Berkeley, J.D. Power and Plug In America (among others) have quantified what EV drivers already know: the uptime performance of public chargers is abysmal. As EV sales have grown, accounts of malfunctioning chargers have spread from bitch sessions… Read more »

How to improve EV battery design with pressure mappings (Webinar)
Engineers involved in battery and EV design and manufacturing have common goals: to maximize performance, lifespan, and safety. Join this session at our Fall Virtual Conference on EV Engineering, presented by Tekscan, to learn why pressure mapping is a critical step in battery R&D for improving battery life, and how to apply it in quality… Read more »
Power electronics thermal limits and how to not exceed them
To someone who isn’t involved in power electronics design, it might seem unreal that the amount of power a component can handle depends more on how effectively waste heat can be removed from it than it does on the specific electrical ratings. Sure, the voltage and current ratings are important (especially the voltage rating), but… Read more »
TWAICE battery analytics platform promises enormously valuable insights at every point in a battery’s lifecycle
How healthy is your battery pack? As the old saw goes, if you can’t measure it, you can’t manage it. As the EV ecosystem develops, there will be an increasing need to measure and manage the performance of battery cells. Cell manufacturers need a standardized way to evaluate test data for new cells; EV designers… Read more »
Battery tech firm Iontra closes $38-million Series B funding round
