Abstract

Disclosed is an apparatus for measuring and classifying a cell pack based on statistical parameters of charge of and discharge from the cell pack. The apparatus includes a control unit, a register, a database, a display, a charger and a load. The register, the database, the display, the charger and the load are connected to the control unit.

Claims

1. An apparatus for measuring and classifying a cell pack based on statistical parameters of charge of and discharge from the cell pack, wherein the apparatus includes:

a control unit 1;

a register 2 connected to the control unit 1;

a database 3 connected to the control unit 1;

a display 4 connected to the control unit 1;

a charger 5 connected to the control unit 1; and

a load 6 connected to the control unit 1.

2. The apparatus according to claim 1, wherein the control unit, the display, the charger and the load can be connected to the cell pack via a battery management system, wherein the control unit commands the charger to charge the cell pack, commands the load to receive electricity from the cell pack, reads data via the battery management system, and registers the data in the register, wherein the database stores data for benchmarking against the data registered in the register.

3. The apparatus according to claim 2, the control unit is connected to the battery management system of the cell pack via a communication interface, wherein the control unit reads the data from the battery management system and register the data in the register via the communication interface.

4. The apparatus according to claim 2, wherein the cell pack includes at least one Li—

H cell.

5. The apparatus according to claim 2, wherein the control unit calculates statistical parameters of the data registered in the register and benchmarks the statistical parameters against the data stored in the database.

6. The apparatus according to claim 5, wherein the result of the benchmarking is taken as the SOH of the cell pack and shown on the display and stored in the database for benchmarking and classification.
