BMS - Auxiliary Controls THERMAL MANAGEMENT HAS EVOLVED TO ENABLE FASTER CHARGING, AND PREDICTIVE THERMAL MANAGEMENT IS GETTING MORE WIDESPREAD Historically, thermal management focused on maintaining the battery within its optimal temperature range. However, with the increasing demand for faster DC charging, modern thermal management systems must now anticipate and manage the heat generated during a DC charging session. Automakers like Tesla, Porsche, Audi and Hyundai have implemented predictive thermal management to enable fast charging. These systems precondition the battery, either by cooling or heating, ensuring the battery is at an optimal temperature upon arrival at the station. Typically the system either starts preconditioning when a driver selects a DC charging station on the navigation system(1), or based on factors such as navigation routes, departure timers, and the driver’s usage behavior(2). Preconditioning can cut down charging time by up to 50%, as shown by a Tesla Model 3 example on the right(3).
