A battery management system that uses a multiple particle reduced order model to manage battery performance of a vehicle, such as an electric vehicle or hybrid electric vehicle is provided. The system can receive a value of a current output and determine, via a multi-particle model, a local current distribution that converges. The system can determine, via the multi-particle model and subsequent to determination of the local current distribution that converges, a concentration distribution. The system can determine, based on the local current distribution, a value of a voltage of the battery. The system can determine, based on the value of the voltage of the battery and the concentration distribution, a temperature of the battery. The system can generate, based on the value of the voltage of the battery or the temperature of the battery, a command to manage a performance of the battery.
