CPUC approves $738 million in EV charging projects for California utilities
The US is soon going to be seriously wired for electric driving, at least on the coasts. The California Public Utility Commission (CPUC) has approved a portfolio of EV charging projects worth a cool $738 million for Pacific Gas & Electric (PG&E), San Diego Gas & Electric (SDG&E) and Southern California Edison (SCE), perhaps the… Read more »
Top circuit protection requirements to consider when designing an automotive battery pack
Littelfuse helps the auto industry navigate new electrical engineering challenges When engineers design a battery pack, they tend to focus first on its core functionality and value proposition. For a high-end energy storage device, those core attributes are typically things like total pack energy density, cost minimization, packaging efficiency, peak power and state-of-the-art thermal management….
