Abstract

The invention relates to a device for measuring the voltage of a nickel hydride power battery assembly module, comprising a circuit board. The circuit board is provided with module voltage test holes which are in one-to-one correspondence to voltage collecting wirings of a power battery module; four groups of connectors are connected behind the circuit board, wherein the insides of the first group and the third group of connectors are connected in parallel; two groups of connectors are respectively connected with a module voltage connection wiring beam six-pin connector of a battery assembly and a voltage collection six-pin connector of the nickel hydride power battery assembly BCU (Battery Control Unit) module; the insides of the second and the fourth groups of the connectors are connected in parallel; and both groups of connectors are respectively connected with a module voltage connection wiring beam eight-pin connector of the battery assembly and a voltage collection eight-pin connector of the nickel hydride power battery assembly BCU module. The device has the advantages of simple production, simple and convenient measuring method, safety and strong operability.

Description

technical field [0001] The invention belongs to the technical field of vehicle power battery detection, and in particular relates to a voltage measuring device for a nickel-metal hydride power battery assembly module. Background technique [0002] The consistency of nickel-hydrogen power battery assembly modules has a huge impact on the power economy, battery assembly performance and battery assembly life of electric vehicles. At present, in the nickel-metal hydride power battery assembly test, the monitoring of the battery module voltage and the consistency analysis of the battery module are particularly important. At present, the preparation work for the voltage measurement of the nickel-metal hydride power battery assembly test module is not only complicated, but also has certain risks. The test preparation cycle is long, the efficiency is low, and there are potential safety hazards. Therefore, it is very necessary to provide a dedicated nickel-metal hydride power batter...
