Battery Charging Method
Abstract
A charging and equalizing method for a battery having a control computer in a charging system in communication with a plurality of module processors. Charging and equalization pauses periodically for voltage measurement by the module processors. The control computer determines when to equalize battery cells in the modules based on their open circuit voltages transmitted by the module processors. A selected group of cells in each module can be equalized. Equalization is carried out in the modules until all of the module processors indicate that equalization has been completed. Charging can then resume until charging is complete or cells reach a maximum voltage given by the control computer. In an alternative embodiment, a selected group of cells may be partially bypassed while charging to reduce the charge rate of the cell.
