Problems solved by technology
However, this method also has obvious disadvantages: 1) This method can only be identified when individual batteries are aging and the internal resistance is too large. When the battery pack as a whole is aging due to long-term use, it is difficult to find abnormalities in the battery; 2) The floating charge terminal of the battery The voltage parameter is difficult to directly reflect whether the battery has a qualified discharge capacity. In some cases, the voltage of the battery is normal during floating charging. Once the discharge terminal voltage drops significantly and the battery discharge capacity is significantly reduced
Therefore, the battery terminal voltage detection method has relatively large limitations and low accuracy.

The invention discloses an industrial UPS battery internal resistance on-line test device, which includes a battery to be tested, a test line, and a detection unit. The detection unit includes a voltage sensor, a current sensor, a temperature sensor, a digital signal processor, and a monitoring system host computer. , the main computer of the monitoring system is respectively connected to a voltage sensor, a current sensor, a temperature sensor, and a digital signal processor. The internal resistance parameters, and all the parameters of the battery to be tested and the battery pack to be tested in the UPS system are sent to the main computer of the monitoring system for monitoring. Online detection and real-time communication can be performed, and abnormal parameters such as battery aging and heating can be found in time.
Description
technical field [0001] The invention relates to a battery internal resistance testing device, in particular to a reliable, accurate, intelligent and convenient on-line testing device for industrial UPS battery internal resistance. Background technique [0002] The existing battery internal resistance test, one is to use the constant current discharge method to manually discharge the battery with a handheld device. This method can find the battery aging problem, but this method has high labor costs, is not smart, and takes a long time to detect. During the detection period, the battery cannot be put into operation, which reduces the working efficiency of the battery, and also brings certain risks to the equipment protected by the UPS, and it is impossible to perform frequent periodic detection, and it is difficult to find and solve the problems of the battery in time. [0003] The other is to use the battery terminal voltage detection method. This method detects the voltage a...
