1. An onboard battery management system comprising:
- a vehicle including a generating unit, a battery charged with power generated by the generating unit, an onboard equipment operating with power supplied from the battery, and a notifying unit providing a notification of a state of the battery;
a portable terminal capable of operating the onboard equipment; and
a server wirelessly communicating with the notifying unit and the portable terminal,wherein the notifying unit includes a monitoring unit detecting a low charge state of the battery where a charge remaining amount of the battery is at or below a predetermined amount or an abnormal state of the battery,when the low charge state or the abnormal state is detected by the monitoring unit, the notifying unit notifies the server of the detection of the low charge state or the abnormal state, andthe portable terminal inquiries of the server about the state of the battery notified to the server by the notifying unit,wherein the vehicle further includes a driving battery that supplies power to a power source for driving the vehicle, andthe battery charged with the power generated by the generating unit differs from the driving battery and has a maximum charging capacity smaller than that of the driving battery,wherein the notifying unit is supplied power from the battery, and the notifying unit switches a power source from the battery to the driving battery when notifying the server of the low charge state.

Abstract
When a low charge state where the charge remaining amount of a battery that supplies power to onboard equipment is at or below a predetermined amount or an abnormal state of the battery is detected, the detection is notified to a server through a communication section. The state notified to the server is recorded in a storage section. When a portable terminal inquires of the server, the state of the battery recorded in the storage section is transmitted to the portable terminal. The portable terminal displays information as to the state of the battery received from the server.
