Electric energy management system, management device for energy storage device, energy storage apparatus and electric energy management method for vehicle

A management device for an energy storage device, the management device comprising:

• a detection part configured to detect an abnormal state of the energy storage device;
• and
• a control part configured to switch an electric current which flows between the energy storage device and a load connected to the energy storage device into a cutoff state when the abnormal state is detected by the detection part,
• wherein the control part is configured to issue an advance notice, notifying of an imminent cut off of the electric current, to an electric energy control part which controls a supply of an electric energy to the load from a generator after the abnormal state is detected by the detection part and before the electric current is switched into the cutoff state,
• wherein the control part is configured to issue the advance notice plural times corresponding to a level of the abnormal state detected by the detection part,
• wherein the generator includes a vehicle generator which is operated along with driving of an engine of a vehicle, and
• wherein the electric energy control part is configured to sequentially perform additional control of the vehicle engine or vehicle generator to control the supply of the electric energy to the load each of the plural times the advance notice is issued.

An electric energy management method for a vehicle,

• wherein the method comprises:
• cutting off an electric current which flows between a load mounted on the vehicle and an energy storage device when an abnormal state of the energy storage device is detected;
• issuing an advance notice, notifying of an imminent cut off of the electric current, after the abnormal state is detected and before the electric current is cut off;
• and
• controlling a supply of an electric energy to the load from a generator mounted on the vehicle based on the advance notice,
• wherein the advance notice is issued plural times corresponding to a level of the abnormal state detected,
• wherein the generator is operated along with driving of an engine of the vehicle, and
• wherein controlling the supply of the electric energy comprises sequentially performing additional control of the vehicle engine or vehicle generator to control the supply of the electric energy to the load each of the plural times the advance notice is issued.
