Building better batteries
Summary
The key to sanity and success While technology is helping EV batteries achieve greater energy density and longer life, the laboratories developing them are also getting bigger. For many other smaller battery manufacturers with modest laboratory operations, it is possible to manually manage and coordinate the few test systems with rudimentary tools, like a spreadsheet. Multiply these parameters by the number of different customer DUTs, sometimes across different sites, and it becomes obvious that the manual data tracking methods no longer suffice to help the battery laboratory managers. Smooth energy conversion at various charging interfaces, both onboard the vehicle and with external EV supply equipment (EVSE) are also important. Holistic design and test at each step of this journey ensures safety and reliability for both the vehicle and its drivers and passengers, and these qualities will continue to provide economies of scale to make batteries more affordable.
