Tapping Secrets of Li-ion Cell Temperature to Improve Cold Performance (Download)

Read this article online.

Lithium-ion batteries are the mainstay in powering today’s electric vehicles (EVs). A major challenge for EV makers has been cold weather performance, much of which boils down to poor lithium-ion cell performance at lower temperatures. While more advanced electrolytes may eliminate the issues in the future, for now, it’s likely to be best addressed by more and better state-of-charge (SOC) and state-of-health (SOH) cell monitoring.
