Electric storage apparatus
First Claim
1. A power control method of an electric storage apparatus that includes an electric storage device and an output terminal connected to the electric storage device via a power supply route in the electric storage apparatus, the output terminal being configured to be electrically connected to a system including an engine, the method comprising:
- detecting a variation value corresponding to an amount of charge of the electric storage device;
determining whether the detected variation value is equal to or lower than an opening threshold, the opening threshold being larger than an engine activation low-threshold by a predetermined value, the engine activation low-threshold being a lowest level of the amount of charge at which the engine is able to be started; and
shutting down the power supply route in the electric storage apparatus, which connects the electric storage device to the output terminal, if the variation value is equal to or lower than the opening threshold.

10. A power control method of an electric storage apparatus that includes an electric storage device, a monitoring apparatus, and an output terminal connected to the electric storage device via a relay, the output terminal being configured to be electrically connected to a system including an engine, the method comprising:
-
detecting a variation value corresponding to an amount of a charge of the electric storage device; determining whether the variation value detected is equal to or lower than an opening threshold, the opening threshold being larger than an engine activation low-threshold by a predetermined value, the engine activation low-threshold being a lowest level of the amount of charge at which an engine connected to the output terminal is able to be started; and executing an opening process to switch a state of the relay from a closed state to an open state if the variation value is equal to or lower than the opening threshold. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18, 19, 20)
