Abstract

The present disclosure relates to the technical field of energy storage devices, and in particular, to a battery module. The battery module includes a set of batteries, a case receiving the set of batteries, and a sampling unit for collecting a voltage signal and a temperature signal of the set of batteries. The sampling unit is provided with a connector, and a stopper for fixing the connector is formed on the case. By forming the stopper on the case, the connector can be directly assembled to the stopper during assembling process of the set of batteries without the need to fix the connector by glue or bolt connection. Therefore, not only an assembling process is simplified, but also the connector is not easily damaged during the assembling process.

First claim

What is claimed is:

1. A battery module, comprising:
a set of batteries;
a case for receiving the set of batteries; and
a sampling unit configured to collect a voltage signal and a temperature signal of the set of batteries,
wherein the sampling unit is arranged on the set of batteries, and the sampling unit is provided with a connector; and
a stopper for fixing the connector within a space formed by the case and is formed on an inner wall within the case,
wherein the case comprises a lower case, and the lower case is provided with a connector outlet;
the stopper comprises a first stopper and a second stopper;
the first stopper and the second stopper are configured to limit the connector in a first direction;
the first stopper is formed by a side of the lower case located at two ends of the connector outlet; and
the second stopper is a first reinforcing rib directly formed on an inner wall of the lower case,
wherein the stopper further comprises a third stopper and a fourth stopper;
the third stopper and the fourth stopper are configured to limit the connector in a second direction; and
each of the third stopper and the fourth stopper is a second reinforcing rib directly formed on the inner wall of the lower case,
wherein the stopper further comprises a fifth stopper and a sixth stopper;
the case further comprises a top cover, and the set of batteries is received in a space formed by the top cover and the lower case;
the fifth stopper and the sixth stopper are configured to limit the connector in a third direction;
the fifth stopper is formed by the inner wall of the lower case; and
the sixth stopper is a stopping plate formed on the top cover and protruding towards the lower case.

2. The battery module according to claim 1 , wherein the sixth stopper is provided with a reinforcing rib.

3. The battery module according to claim 1 , wherein the stopper further comprises a reinforcing rib directly formed on the case.

4. The battery module according to claim 1 , wherein the stopper further comprises a stopping plate directly formed on the case.

5. The battery module according to claim 4 , wherein the stopper further comprises a buckle located at an end of the stopping plate, and the end is facing away from the inner wall of the case.
