Abstract
A radio frequency energy management system includes a number of battery control modules and/or a control unit that are configured to exchange battery operating parameter/performance information and control signals by radio frequency. Each battery control module includes one or more sensing elements to measure one or more operating parameter of a respective battery, and at least one device selected from the group including a radio frequency receiver, a radio frequency transmitter, a memory device, a controller, control devices, a signal blocking device, and combinations thereof. The control unit is configured to monitor and control the operating parameters of the batteries and includes a radio frequency receiver and a radio frequency transmitter. The control unit evaluates data transmitted from battery control modules according to a predetermined control system program, and transmits a predetermined control command to one or more battery control modules to achieve battery equalization and battery thermal management. The energy management system can also include one or more device for identifying the relative location of a battery control module in the system, and an interface to permit communication with battery control modules by another device independent of the control unit. Radio frequency signals are transmitted between the control unit and each battery control module, and between battery control modules, without additional wiring, thereby eliminating the disadvantages of wired-type systems.
