PSDcast – A Wireless Battery Management System

Karl-Heinz Steinmetz, who leads TI’s hybrid and electric vehicle and powertrain sector team

Electric vehicles rely on battery management systems to maximize their power, range, and efficiency. Every battery cell in the EV has to be wired to a BMS, and since more cells means a higher charge capacity – leading to a longer electric range – manufacturers pack as cells in there as they can. And that ma
