[0002] Storage batteries are widely used in industrial and mining enterprises. In the above enterprises, storage batteries are often composed of multiple batteries, and together with DC charging and discharging equipment, they constitute the power source of the control system of industrial and mining enterprises. Since the DC system is mainly used for the control components of various equipment, the stability and safety of the system are extremely important. Regularly measuring and recording the voltage of battery cells is an extremely important task in the operation and management of the above enterprises.

[0003] Due to the wide variety of batteries and the different shapes of battery poles, the current use of a multimeter to measure the voltage of a single battery pack is usually performed by one or two measurement or recording personnel. The measurement personnel need to hold one side of the multimeter with both hands, insert the test lead into the battery rack, place the tip of the test lead close to the pole of the battery being measured, and then record the single voltage. This method requires both hands to measure voltage, and the test lead needs to be pressed tightly against the pole with appropriate force. The measured voltage is prone to instability. At the same time, the hand is close to the charged part of the battery during measurement, so there is a certain degree of measurement difficulty and a certain safety risk. Utility Model Content
