Abstract

A battery module comprises at least one battery, and one or more memory sections for memorizing management information of the at least one battery at cutting operation of connection, when a connection between the at least one battery and at least one external device is cut, and the at least one battery and the memory sections are structured as one body.

Claims

1. A battery managing system comprising:

a battery module, which further comprises;

at least one battery;

a memory section for memorizing management information of said at least one battery; and

a clock section for generating information relating to time information among management information of said at least one battery, wherein

said at least one battery and said memory sections are structured as one body; and

a managing section connected to said memory section for judging whether or not the battery module can be exchanged based on use information of said battery memorized in said memory section, and for memorizing the use information of said battery generated by using time information from said clock section to said memory section.

2. The battery managing system according to claim 1, further comprising a power supply control section for intercepting a power supply to said memory section and said clock section when exchanging said battery module.

3. A battery managing system comprising:

a battery module, which further comprises;

at least one battery;

a memory section for memorizing management information of said at least one battery;

a clock section for generating information relating to time information among management information of said at least one battery, wherein

said at least one battery and said memory sections are structured as one body; and

a connection terminal which is to be connected to an external device, wherein the connection of said battery module and said external device is recognized by said external device by connecting said connection terminal with a terminal provided in said external device; and

a managing section connected to said memory section for judging whether or not the battery module can be exchanged based on use information of said battery memorized in said memory section, and for memorizing the use information of said battery generated by using time information from said clock section to said memory section.

4. The battery managing system according to claim 3, further comprising a power supply control section for intercepting a power supply to said memory section and said clock section when exchanging said battery module.

5. A battery managing system comprising:

a battery module, which further comprises;

at least one battery;

a memory section for memorizing management information of said at least one battery; and

a clock section for generating information relating to time information among management information of said at least one battery, wherein

said at least one battery and said memory sections are structured as one body;

a managing section connected to said memory section and said clock section for judging whether or not the battery module can be exchanged based on use information of said battery, and for memorizing the use information of said battery generated by using time information from said clock to said memory section; and

a GND level fixation section for fixing the signal level on a signal line between said managing section and said battery module at the GND level when exchanging said battery module.

6. The battery managing system according to claim 5, further comprising a power supply control section for intercepting a power supply to said memory section and said clock section when exchanging said battery module.

7. A battery managing system comprising:

a battery module, which further comprises;

at least one battery;

a memory section for memorizing management information of said at least one battery;

a clock section for generating information relating to time information among management information of said at least one battery, wherein

said at least one battery and said memory sections are structured as one body; and

a connection terminal which is to be connected to an external device, wherein the connection of said battery module and said external device is recognized by said external device by connecting said connection terminal with a terminal provided in said external device; and

a managing section connected to said memory section and said clock section for judging whether or not the battery module can be exchanged based on use information of said battery, and for memorizing the use information of said battery generated by using time information from said clock section to said memory section; and

a GND level fixation section for fixing the signal level on a signal line between said managing section and said battery module at the GND level when exchanging said battery module.

8. The battery managing system according to claim 7, further comprising a power supply control section for intercepting a power supply to said memory section and said clock section when exchanging said battery module.
