An electrical vehicle battery management system (BMS) 102 manages charging and discharging of a battery unit 202 of an electrical vehicle. The battery management system determines from sensor 206 signals parameters of battery modules 204 of the battery unit that are indicative of a state of charge (SOC) of the battery modules, and adjusts charge stored within the battery modules mutually to balance charge stored within the battery modules. User information indicative of a status of operation of the battery unit is provided to a user of the electrical vehicle via a user interface 212. The battery management system may include a data processing arrangement 208 including an interfacing data processor 210 for receiving sensor data from the battery unit and for providing control signals back to the battery unit for battery cell charge balancing purposes or for battery unit protection purposes, and a user interface data processor for providing user data indicative of operation of the battery unit.
