Storage battery discharge comprehensive tester

Abstract

The invention relates to a storage battery discharge comprehensive tester which is a device used for storage battery constant-current discharge, battery detection and battery capacity judgement. The storage battery discharge comprehensive tester comprises a discharge unit which realizes the constant current discharge, a monitoring unit which provides the discharge unit with comparison current and monitors the capacity of the storage battery and a data processing unit which processes data and draws a drawing for analyzing. The storage battery discharge comprehensive tester realizes the constant current discharge of the current and can simultaneously measure the capacity of the storage battery at real time to prevent the overdischarge of the storage battery by the mutual action of the discharge unit, the monitoring unit and the data processing unit.

Description

technical field [0001] The invention relates to a battery constant current discharge, battery detection and battery capacity judging device. Background technique [0002] Batteries are widely used in important departments such as electric power and communications to provide uninterrupted power supply for equipment such as protection, control, communications, and computers. Therefore, it is very important whether the actual capacity of the battery is normal. For this reason, it is necessary to conduct regular charge and discharge tests on the battery. [0003] There are two main types of traditional storage battery discharge devices. One type uses resistive elements as the discharge load. As the discharge process progresses, the voltage of the battery decreases gradually, and the discharge current decreases. At this time, the discharge resistance must be manually adjusted to maintain the discharge current. At the same time, use a voltmeter to manually measure the battery volt...

Problems solved by technology

[0003] There are two main types of traditional storage battery discharge devices. One type uses resistive elements as the discharge load. As the discharge process progresses, the voltage of the battery decreases gradually, and the discharge current decreases. At this time, the discharge resistance must be manually adjusted to maintain the discharge current. At the same time, use a voltmeter to manually measure the battery voltage. If the number of batteries is relatively large (such as 108), the workload of manual measurement will be greatly reduced, and real-time detection cannot be achieved; the second type uses a linear circuit such as a series regulator. Mode

This method is bulky and consumes a lot of power, so it is not suitable for making high-current loads

Although the above two discharge detection methods have been applied to a certain extent, the human interference factors are large, the discharge current accuracy is not high, the voltage detection is not real-time, it is difficult to realize high-current discharge, and the operation is complicated, which is not very practical in the actual use process. convenient
