Abstract

A battery device with a battery module that includes multiple secondary cells, and the battery module is provided with a positive pole and a negative pole. Moreover, the battery module is placed inside an insulating housing with a contact element, which is connected to the positive pole and to the negative pole and through which the positive pole and the negative pole may be connected to an electronics unit of a battery system. Moreover, the invention relates to a battery system and a method for assembling a battery system.

First claim

The invention claimed is:

1. A battery system, comprising:
a battery module with multiple secondary cells, wherein each secondary cell of the multiple battery cells is located in a respective receptacle;
a framework having a rear wall configured to combine the multiple secondary cells, wherein each secondary cell is configured to be inserted into the framework in a plug and play manner, said battery module is provided with a positive pole and a negative pole, the battery module is located inside an insulating housing with a contact element, which is connected to the positive pole and the negative pole and through which the positive pole and the negative pole are configured to be connected to an electronics unit that is configured to recognize individual cell voltages of each secondary cell.

2. The battery system according to claim 1 , wherein the housing is an acid-proof material.

3. The battery system according to claim 1 , wherein a traction battery or a starter battery for a motor vehicle is received in the insulating housing as the battery module.

4. The battery system according to claim 1 , wherein the contact element comprises a contactor.

5. The battery system of claim 1 , wherein
the contact element is configured to be connected to the electronics unit via a contact device.

6. The battery system according to claim 5 , wherein the contact device comprises a contactor.

7. The battery system according to claim 5 , wherein the battery system is designed as a stationary storage battery for the purpose of balancing out the load spikes of a mains grid.
