Abstract

In order to identify whether each of the cells in a storage battery system is available, the storage battery system is equipped with secondary cell packs, information storage parts which are respectively installed to the secondary cell packs to store cell information on the respective secondary cell packs, and monitor device which judges whether loading to the storage battery system is possible according to the cell information stored in the information storage part.

Claims

1. A storage battery system comprising:

a plurality of secondary cell pack;

an information storage part configured to be attached to each of said plurality of secondary cell pack and store cell information concerning said each secondary cell pack; and

a monitoring device configured to judge whether or not said each secondary cell pack can be mounted on said storage battery system based on said cell information;

wherein said monitoring device judges whether or not a combination of said plurality of secondary cell pack is appropriate to judge whether or not mounting is possible.

3. The storage battery system according to claim 1, further comprising:

a storage part configured to store system standard information that indicates a specification range of a mountable secondary cell pack, wherein specification information indicating specification of said each secondary cell pack is stored in said information storage part as said cell information, and said monitoring device compares said specification information of said plurality of secondary cell pack with said system standard information to judge whether or not mounting is possible.

4. The storage battery system according to claim 3, wherein said specification information includes at least one of an available range of charging voltage, an available range of discharging voltage, an available range of charging current, an available range of discharging current, a capacity range, an input/output range, a temperature range, and a resistance value range.

5. The storage battery system according to claim 1, further comprising:

a current state detection part which is provided corresponding to said each secondary cell pack and detects current state of said each secondary cell pack, wherein said cell information includes current information that indicates a current state of said each secondary cell pack, said current state detection part stores said detected current state in said information storage part as said current information, and said monitoring device compares current states between said plurality of secondary cell pack to judge whether or not mounting is possible.

6. The storage battery system according to claim 5, wherein said current information includes at least one of a current charging capacity of said each secondary cell pack, a current internal resistance, a highest operating temperature up to present time, a lowest operating temperature up to present time, total operating time and number of cycles.

7. The storage battery system according to claim 1, wherein said monitoring device is connected to both end of whole of said plurality of secondary cell pack, and said monitoring device obtains said cell information from said information storage part, via a closed circuit that is formed of said monitoring device and said plurality of secondary cell pack.

8. The storage battery system according to claim 1, further comprising:

a wireless part attached to said each secondary cell pack and wirelessly transmits said cell information stored in said information storage part to said monitoring device,

wherein said monitoring device comprises a wireless receiving part configured to receive said cell information that is wirelessly transmitted.

2. (canceled)

9. A storage battery monitoring device comprising:

a cell information acquisition part configured to acquire cell information concerning a plurality of secondary cell pack from said plurality of secondary cell pack; and

a cell identification part configured to judge whether or not mounting on a storage battery system is possible, based on said acquired cell information, wherein said cell identification part judges whether or not a combination of said plurality of secondary cell pack is appropriate to judge whether or not mounting is possible.

10. The storage battery monitoring device according to claim 9, wherein said cell information includes current information that indicates current state of said each secondary cell pack, and said cell identification part compares current states of said plurality of secondary cell pack based on said current information to judge whether or not mounting is possible.

11. A secondary cell pack mounted on a moving vehicle, comprising:

at least one of single cell; and

a information storage part configured to store cell information concerning said single cell, wherein when being attached to a storage battery system, said cell information is transmitted to a monitoring device provided in said storage battery system, and said monitoring device judges whether or not a combination of said plurality of secondary cell pack is appropriate to judge whether or not mounting is possible.

12. A storage battery monitoring method, comprising:

acquiring cell information concerning each of a plurality of secondary cell pack, from said plurality of secondary cell pack; and

judging whether or not mounting on a storage battery system is possible, based on said acquired cell information, wherein said judging comprises;

judging whether or not a combination of said plurality of secondary cell pack is appropriate to judge whether or not mounting is possible.

13. A storage battery monitoring method according to claim 12, wherein said cell information includes current information that indicates a current state of said each secondary cell pack, and said judging comprises:

comparing current states of said plurality of secondary cell pack based on said current information to judge whether or not mounting on a storage battery system is possible.
