Abstract
Equipment and methods for estimating and regulating the state of charge (SOC) of a battery in a hybrid fuel cell-battery system for use in a moving vehicle. The SOC is continuously estimated and the fuel cell power is regulated to maintain the SOC at a level such that the battery has enough stored energy to operate motors used in the vehicle, and enough spare capacity to accept regenerative energy from these motors during further operations.
