Embodiment 1

[0020] figure 1 and Figure 6 is a block diagram showing components of the battery pack 100 and components of the electronic device 200 connectable to the battery pack 100 .

[0021] The battery pack 100 is a battery pack connectable to the electronic device 200 . The battery pack 100 is connected to the electronic device 200 by being housed in the battery pack housing portion of the electronic device 200 . The battery pack 100 includes a battery unit 101, a first positive terminal 102a, a first negative terminal 102b, a second positive terminal 103a, a second negative terminal 103b, a current detection circuit 104, a control unit 105, a FET unit 106, a communication unit 107 and a communication Terminal 108.

[0022] The battery cell 101 is a rechargeable battery cell such as a lithium ion battery cell or the like. The battery cell 101 includes one or more battery cells.

[0023] For example, the first positive terminal 102a and the first negative terminal 102b are termi...

Embodiment 2

[0066] Various functions, processes, or methods described in Embodiment 1 can also be realized as a result of a personal computer, microcomputer, CPU (Central Processing Unit), or processor executing the program. In Embodiment 2, a personal computer, microcomputer, CPU or processor will be referred to as "computer X". Furthermore, in Embodiment 2, a program for controlling the computer X and realizing various functions, processes, or methods described in Embodiment 1 will be referred to as "program Y".

[0067] As a result of the computer X executing the program Y, various functions, processes, or methods described in Embodiment 1 are realized. In this case, the program Y is supplied to the computer X via a computer-readable storage medium. The computer-readable storage medium in Embodiment 2 includes at least one of a hard disk device, a magnetic storage device, an optical storage device, a magneto-optical storage device, a memory card, a volatile memory, and a non-volatile ...

Abstract

The invention discloses a battery pack, a control method, and a storage medium. The battery pack is connectable to an electronic device. The battery pack includes a positive terminal, a negative terminal, and a cutoff member. The cutoff member cuts off a current flowing from the battery cell to the electronic device when the current flowing from the battery cell to the electronic device exceeds a maximum current value. The battery pack further includes a control means for changing the maximum current value based on the number of positive and negative terminals connected to the electronic device.

Description

technical field [0001] The present invention relates to a battery pack, a method, and a storage medium storing a program. Background technique [0002] A battery pack that supplies power to electronic devices includes a protection circuit for protecting battery cells of the battery pack from overcurrent. If the current flowing to the battery cell exceeds the maximum value, the protection circuit may cut off the current flowing to the battery cell by opening the switching element. [0003] Japanese Patent Laid-Open No. 2001-286068 describes changing a current value for judging whether to cut off the current flowing from the positive terminal to the battery cell according to the temperature, voltage or remaining capacity of the battery pack. [0004] However, the battery pack described in Japanese Patent Laid-Open No. 2001-286068 is not a battery pack including positive and negative terminals. Therefore, in the case where the battery pack described in Japanese Patent Laid-Op...
