Energy supply system comprising an energy storage device and method for actuating coupling devices of the energy storage device

摘要

The invention relates to an energy supply system having an energy storage device. The energy storage device has a plurality of energy storage modules that are serially connected in at least one energy supply branch, each comprising an energy storage cell module having at least one energy storage cell, and a coupling device having coupling elements configured to selectively switch the energy storage cell module into the respective energy supply branch, or to circumvent same, and comprising a plurality of driver devices, each dedicated to one of the energy storage modules, and coupled to one of the energy storage modules, and which are configured to actuate the coupling elements of the coupling devices according to a driver signal. The energy supply system further comprises a control device, which is coupled to the driver devices by way of a control signal line, and which is configured to emit a control signal to the driver devices by way of the control signal line, which is provided with a physical control signal parameter, into the value of which a control mode for the driver devices is coded. The driver devices are configured to receive the control signal, and to generate the respective driver signal subject to the value of the control signal parameter, and a control mode assignment that can be predetermined.
