Abstract
A radio frequency energy management system includes a number of battery control modules and an control unit, each configured to transmit and receive radio frequency signals comprising information relating to the operating parameters of batteries in a battery pack, and control commands for regulating the operating parameters of such batteries. Each battery control module is configured to monitor one or more operating parameter of a respective battery, and to regulate one or more operating parameter according to a control system program in the control unit. Each battery control module includes one or more sensing elements to measure one or more operating parameter of a respective battery, a radio frequency receiver, and a radio frequency transmitter. The control unit is configured to monitor and control the operating parameters of the batteries and includes a radio frequency receiver, configured to receive a radio frequency signal transmitted by the radio frequency transmitter in each battery control module, and a radio frequency transmitter configured to transmit a radio frequency signal capable of being received by the radio frequency receiver in each battery control module. The control unit evaluates data transmitted from each battery control module according to a predetermined control system program, and transmits a predetermined control command to one or more battery control module to achieve battery equalization. Radio frequency signals are transmitted between the control unit and each battery control module without additional wiring, thereby eliminating the disadvantages of wired-type systems.
