Embodiment Construction

[0013] Refer to the following Figure 1 to Figure 5 One embodiment of the present invention will be described. The battery management device according to the embodiment of the present invention is configured to manage used batteries (secondary batteries) that are used (reused) for the second time after being used once. In addition, in the following, an example in which a battery management device is configured especially for a battery last used in an electric vehicle having a running motor, such as an electric vehicle and a hybrid vehicle, will be described.

[0014] figure 1 It is a figure which shows the schematic structure of the battery 1 which is the object of the battery management apparatus of this embodiment. The battery 1 is mounted on an electric vehicle, and is mainly used to share driving power to a traveling motor. Such as figure 1 As shown, a battery (battery device) 1 has a battery main body 10 , a battery ECU (Electronic Control Unit) 2 , a terminal block (...

Abstract

A battery management apparatus configured to manage a battery to be reused, including an electronic control unit including a microprocessor and a memory connected to the microprocessor. The microprocessor is configured to perform acquiring a battery information including an information on a failure and repair history of the battery before the battery is reused, the memory is configured to store the battery information, and the microprocessor is configured to further perform determining a restriction imposed on the battery when the battery is reused, based on the battery information stored in the memory.

Description

technical field [0001] The invention relates to a battery management device for managing secondary used batteries. Background technique [0002] Conventionally known as such a device is a device in which a management server acquires information on a battery mounted on a mobile body for primary use, and the management server notifies the user of the battery information when the battery is secondarily used by the user. Such a device is described in Patent Document 1, for example. The device described in Patent Document 1 transmits information such as past usage status and records of the battery as battery information to the user. [0003] However, the device described in Patent Document 1 only notifies the user of information such as past usage status and records, and may not be able to properly use the battery for secondary use.
