Abstract
A storage battery pack includes: a secondary battery; and a circuit that includes a power consumer which consumes power of the secondary battery, and that causes the power consumer to consume a remaining power of the secondary battery until a voltage of the secondary battery reaches a voltage lower than a discharge cutoff voltage.
Claims22
A storage battery pack comprising:
- a secondary battery;
- a circuit that includes a power consumer which consumes power of the secondary battery, and that causes the power consumer to consume a remaining power of the secondary battery until a voltage of the secondary battery reaches a voltage lower than a discharge cutoff voltage;
- a receiver that receives a command for activating the circuit from an external entity;
- a controller;
- and
- a memory including a set of executable instructions that, when executed by the controller causes the controller to perform operation including:
- activating the circuit and causing the power consumer to consume the remaining power of the secondary battery, when the receiver receives the command from the external entity via wireless communication.
