Abstract

The invention relates to an intelligent storage battery monitoring and maintaining device. The device comprises a storage battery discharge main circuit, a storage battery voltage detection circuit, a storage battery discharge current detection circuit, a temperature measuring circuit, a working power supply circuit, an RS485 communication interface circuit and an abnormal alarm indication circuit, wherein the storage battery discharge main circuit takes a processor as a control core, and the RS485 communication interface circuit is powered by an upper computer and isolated by a device main circuit. The device can be independently arranged all storage batteries, and can conduct voltage, temperature, internal resistance and load tests on the storage batteries under an offline or online state. Regardless of availability of communication between the device and the upper computer, the voltage, temperature, internal resistance and load tests can be conducted on the storage batteries under offline or online state, voltage, and when temperature and internal resistance measurement results and the final voltage discharged by the loads are compared with a preset value in programs of the processor and abnormal conditions are found out, a sound and optical alarm indication circuit gives alarms, thus playing roles in monitoring and maintaining the storage batteries under the offline and online state.

Description

Technical field [0001] The invention relates to an intelligent monitoring and maintenance device for a storage battery, especially capable of performing voltage, temperature, internal resistance and load tests on the storage battery when the storage battery is offline or online. Background technique [0002] Currently known batteries need maintenance in fact, so there are various off-line (charger off) battery maintenance testers and on-line (charger off) battery pack monitoring systems. Such as offline load capacity tester, battery internal resistance tester that can be used offline or online, and online battery pack voltage, temperature and internal resistance monitoring system. However, both offline and online battery testers need to test the battery regularly, and all online battery pack voltage, temperature and internal resistance monitoring systems have many signal lines, which increases the difficulty and complexity of wiring. It affects the test accuracy and reduces...
