How current sensing impacts electric vehicles: part 2
Part 1 of this blog addressed current shunts and Hall-effect sensor designs. This part discusses current transformers and new technology options, such as magnetoresistance and diamond quantum sensors. One of the significant issues in today’s electric vehicles (EVs) is the ongoing evolution of technology, with the standards evolving as well. In the 100+ years that […]
How current sensing impacts electric vehicles: part 1
The need to transition from gasoline and diesel (fossil fuels) powered vehicles to electric vehicles (EVs) to reduce carbon dioxide levels has revealed many controversial issues. Common issues include implementation timing, required infrastructure (including fast-charging multi-vehicle systems), legislated rather than consumer-based adoption, ongoing system enhancements, and new critical raw materials sources. Current sensing technology is […]
