Fast charging enabled by advanced battery management systems

May 01, 2020 | Case Study

While battery developers strive toward increased energy densities, high cycle life, and lower costs, battery management systems (BMS) offer a solution to maximize battery performance and optimize charging times. Electric vehicles have the most to gain from fast charging software that can charge at rates up to 7C. Based on total predicted EV sales, 425,000 fast chargers will need to be deployed globally by 2025, requiring a battery system that can accept the rapid charge rate without deteriorating battery performance or lifetime. Many limitations lie within the battery itself, reflected by Porsche falling short of its 350 kW charging goal with the Taycan. However, BMS software can still deliver fast charging without battery limitations or power requirements while offering better battery health.
