Electric storage apparatus
First Claim
1. A battery, comprising:
- an output terminal configured to be electrically connected to a system including an engine;
an electric storage device;
a monitoring apparatus including a detector and a controller, the detector being configured to detect a variation value corresponding to an amount of charge of the electric storage device; and
a relay connected to the output terminal and the electric storage device,wherein the controller is configured to;
determine whether the variation value detected by the detector 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
execute 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.

Abstract
An electric storage apparatus includes an output terminal configured to be electrically connected to a system including an engine, an electric storage device, a monitoring apparatus including a detector and a controller, and a relay disposed between the output terminal and the electric storage device. The detector is configured to detect a variation value corresponding to an amount of charge of the electric storage device. The controller is configured to determine whether the variation value is equal to or lower than an opening threshold, and execute an opening process to switch the relay from a closed state to an open state if the variation value is equal to or lower than the opening threshold. The opening threshold is larger than an engine activation low-threshold by a predetermined value. The engine activation low-threshold is a lowest level of the amount of charge at which the engine is able to be started.
