DUAL ENERGY-STORAGE FOR A VEHICLE SYSTEM
First Claim
1. A switching control unit for the controlling the transfer of electrical power in a hybrid electrical vehicle from at least one of a starter generator and a supercapacitor bank to at least one of a service battery and a plurality of electrical devices, the switching control unit comprising:
- a switching device adapted to selectively connect/disconnect the at least one of the starter generator and the supercapacitor bank to/from the at least one of the service battery and the plurality of electrical devices; and
a switch controller adapted to;
measure a voltages across the supercapacitor bank to generate a bank voltage signal;
measure a voltage across the service battery to generate a service voltage signal; and
control the switching device to connect/disconnect the at least one of the starter generator and the supercapacitor bank to/from the at least one of the service battery and the plurality of electrical devices in response to the bank voltage signal and the service voltage signal.

Abstract
A switching control unit for the controlling the transfer of electrical power in a vehicle from at least one of a starter generator and a supercapacitor bank to/from at least one of a service battery and a plurality of electrical devices is provided. A switching device selectively connects/disconnects the at least one of the starter generator and the supercapacitor bank to/from the at least one of the service battery and the plurality of electrical devices. A switch controller is adapted to measure a voltage across the supercapacitor bank to generate a bank voltage signal, to measure a voltage across the service battery to generate a service voltage signal, and to control the switching device to connect/disconnect the at least one of the starter generator and the supercapacitor bank to/from the at least one of the service battery and the plurality of electrical devices in response to the voltage signals.
