Abstract
A battery-powered vehicle and a vehicle battery maintenance system that includes a battery charger that monitors energy consumption data from the vehicle battery to generate charging instructions to a charger. A central data unit (CDU) can determine whether if a vehicle electrical load is consuming too much energy and then generate instructions to the vehicle controller to limit the energy consumption. The CDU can notify an offsite central computer if the battery has not been charged according to charging instructions.
