Power battery package system high voltage interlocking connector detection system

Abstract

The invention relates to a power battery package system high voltage interlocking connector detection system. The detection system comprises a plurality of high voltage interlocking connectors, each of the high voltage interlocking connectors comprises a plug and a socket, which are connected together. A signal generator, a signal detector, and a processor are provided. Two ends of the contacts ofeach socket are parallel connected with a detection resistor, and the signal generator is connected with all of the detection resistors, and the signal detector is connected with two ends of each detection resistors. Compared with the prior art, the invention is advantageous in that the connection state of all of the high voltage interlocking connectors can be detected, and the current state of each concrete high voltage interlocking connector can be discriminated concretely, and in addition, the battery package system can be detected timely during the use or after the assembly of the connectors, and therefore high efficiency and accuracy are realized at the same time, and the use safety of the battery package high voltage circuit can be guaranteed.

Description

technical field [0001] The invention relates to the field of high-voltage interlock connectors, in particular to a detection system for a high-voltage interlock connector of a power battery pack system. Background technique [0002] The power battery pack system is widely used in new energy electric vehicles. With the improvement of the performance of new energy electric vehicles, the demand for battery pack capacity and voltage is also expanding. At the same time, the risk of high-voltage electric shock in the battery pack system increases. The existing common means of preventing high-voltage electric shock is to realize the interconnection of multiple subsystems of the power battery pack system through a high-voltage interlock (HVIL) connector. However, the existing high-voltage interlock connectors have the following problems: 1. The high-voltage interlock connectors adopt a mutually independent casting net installation structure. Once one of the high-voltage interlock co...

Problems solved by technology

However, the existing high-voltage interlock connectors have the following problems: 1. The high-voltage interlock connectors adopt a mutually independent casting net installation structure. Once one of the high-voltage interlock connectors fails, precise positioning cannot be performed, and a It takes manpower and material resources to check and eliminate; 2. Whether the plug and socket connection of the high-voltage interlock connector is in place can only rely on its own mechanical structure. Once the plug and socket are not assembled in place or loose during use, false alarms are prone to occur , and cannot be detected in time, and its overall protection for the battery pack system is poor
