Voltage-temperature integrated testing device of storage battery set

Abstract

The invention discloses a voltage-temperature integrated testing device of a storage battery set. The device is programmed to be controlled by programmable chips, voltage of a single battery of the storage battery set is insulated and gated by an optocoupler relay, and an integrated operational amplifier performs differential mode operation on voltage at two ends of a battery cell of the storage set to acquire voltage of the single battery. On the basis of single battery voltage testing, a temperature testing optocoupler is controlled to be off through the programmable chips to test temperature of current gated batteries. Compared with the prior art, the voltage-temperature integrated testing device of the storage battery set realizes simultaneous integrated testing of voltage and temperature of the single battery in the storage battery set in series, overcomes the defect of separated testing of battery voltage and battery temperature in the past, and guarantees real-time synchronicity of battery voltage and battery temperature.

Description

technical field [0001] The invention relates to the field of detection of series battery packs, in particular to an integrated inspection device for voltage and temperature of battery packs. Background technique [0002] Series battery packs are widely used in various industries and fields such as electric vehicles, high-power energy storage equipment, and emergency power supplies. The battery pack is generally composed of multiple single cells connected in series. The performance of the battery plays a decisive role in the performance of the entire battery pack. The inspection can find out the performance status of the batteries in the battery pack, and the problematic batteries can be dealt with as soon as possible to avoid affecting the entire battery pack and ensure the efficient, safe and reliable operation of the battery pack. [0003] The previous battery inspection equipment paid attention to the inspection of the voltage of each battery cell, but due to the differen...

Problems solved by technology

[0003] The previous battery inspection equipment paid attention to the inspection of the voltage of each battery cell, but due to the different use conditions of each battery, the internal structure may change during use, and the temperature may be much higher than that of other batteries in the same group. Realizing the temperature inspection of each battery will increase the cost of battery inspection equipment. In order to save costs, in the past, the temperature of several points in the battery pack was measured, and the average value was taken as the battery temperature
