Introduction
Battery Management Systems (BMS) play a critical role in the performance, safety, and longevity of battery-powered golf carts and low-speed vehicles (LSVs). These vehicles typically operate with large-capacity batteries, such as 48V, 72V, 105Ah, and 160Ah, which require precise management to ensure reliable and efficient operation. This application note discusses the importance of BMS in addressing key issues such as large startup currents, overload protection, and State of Charge (SOC) calculation.
Issues in Golf Carts and Low-Speed Vehicles
Large Startup Current
Golf carts often experience large startup currents, which can strain the battery and reduce its lifespan. Managing this startup current is crucial to prevent damage to the battery and ensure smooth operation of the vehicle.
Overload Protection
Overload conditions can occur due to excessive demand from the motor or other electrical components. Without proper management, overloads can lead to overheating, battery degradation, or even failure.
SOC Calculation
Accurate SOC calculation is vital for understanding the remaining battery capacity and ensuring the vehicle does not unexpectedly run out of power. Precise SOC estimation helps in optimizing battery usage and scheduling recharges.
