Abstract

The invention provides a storage battery parameter measurement device which comprises a power supply module which is composed of storage batteries, an internal resistance measurement module, a voltage measurement module, a temperature measurement module and a display module. The internal resistance measurement module is used for measuring the internal resistance of each storage battery in the power supply module. The voltage measurement module is used for measuring the voltage of each storage battery in the power supply module. The temperature measurement module comprises storage battery temperature measurement chips which are arranged on the surfaces of the storage batteries. The power supply module supplies power for a single chip microcomputer which obtains the internal resistance, the voltage and the temperature of the storage battery according to a signal which is transmitted by the internal resistance measurement module, the voltage measurement module, and the temperature measurement module in sequence. The display module is used for displaying the internal resistance, the voltage and the temperature of each storage battery. The storage battery parameter measurement device possesses functions of measuring the voltage, the internal resistance and the temperature of the storage battery, is capable of measuring parameters such as voltages, resistances and temperatures of a plurality of storage batteries, and a storage battery maintainer can rapidly locate to the storage battery with bad performance parameters according to the voltage, the internal resistance and the temperature.

Description

technical field [0001] The invention relates to the technical field of storage batteries, in particular to the field of state monitoring of storage batteries, in particular to a storage battery parameter measurement device. Background technique [0002] Batteries are used more and more in electric vehicles and hybrid vehicles, and the battery system generally adopts a series connection method. The state deterioration of some single batteries in the battery pack directly affects the overall capacity state of the battery pack, that is, the overall capacity state of the battery pack is determined by the capacity of one or several batteries in the most severely degraded state in the system. Therefore, it is very necessary to accurately measure the state of each single battery to prevent battery failure. [0003] Battery failure or insufficient capacity may cause major accidents. Therefore, battery detection and monitoring has always been a hot topic of research at home and abro...
