Abstract

The invention discloses a power consumption detection device for a rechargeable battery protection plate and comprises a base, wherein an installing plate is arranged on the base, a downward pressing driving device is arranged on the installing plate, the lower end of the downward pressing driving device is provided with a detection plate, a plurality of measurement probes are arranged on the detection plate, each measurement probe is respectively connected with the positive and negative output ends of serially connected batteries in a battery pack and the contact point between the adjacent batteries in a one-to-one correspondence way through a current meter, two positioning plates are arranged under the detection plate arranged on the base, and detection step surfaces are respectively arranged on the two positioning plates. The power consumption detection device for the rechargeable battery protection plate has the advantages that the power consumption values of all sampling points on the protection plate can be measured in one step, the measurement efficiency is greatly improved, and the labor and the money of enterprises are saved.

Description

technical field [0001] The invention relates to a device for detecting power consumption of a rechargeable battery protection board. Background technique [0002] Since lithium batteries cannot be charged and discharged by overcharge, overdischarge, overcurrent, short circuit and ultra-high temperature, the battery packs of lithium batteries are equipped with battery protection boards to protect lithium batteries. When in use, connect the positive and negative output terminals of the batteries connected in series in the battery pack and the contact points between adjacent batteries with the sampling points on the battery protection board, and rely on the protection board to instantly control the on-off of the current loop to prevent the battery from charging and discharging. was destroyed when. [0003] Since the rechargeable battery pack may take a long period from the completion of production to the customer's use, the power consumption of the protection board must be con...
