Abstract

The present invention relates to a storage battery capacity testing and repairing device, in particular to a capacity testing and repairing instrument which uses constant-current discharge to test battery capacity and uses high-frequency pulse to repair storage batteries. The present invention introduces a microprocessor on the basis of the prior lead acid storage battery capacity testing and repairing instrument, and controls generated frequency, duty cycle, pulse strength and adjustable high-frequency pulse sequences through software so as to repair a storage battery. A digital storage battery capacity testing and repairing instrument comprises an AC/DC converting circuit, a DC converting circuit, a current-limiting circuit, a loading component, a relay, a constant-current discharge circuit, a microcontroller circuit, a key and a digital drive display circuit. The capacity testing and repairing instrument is very simple to operate and use, intuitive in data display, low in cost, good in repair effect, and fast to take effect, having great economic benefit and social environmental protection benefit in determining battery capacity and reducing total discard quantity of batteries.

Description

technical field [0001] The invention relates to a storage battery capacity testing and repairing device, in particular to a capacity testing and repairing instrument which uses constant current discharge to test the battery capacity and high-frequency pulses to repair the storage battery. Background technique [0002] Lead-acid batteries have been widely used in various industries since their invention, especially in recent years with the popularization of electric bicycles and electric tricycles, their demand has grown at an alarming rate. [0003] How much capacity the battery has at any time is a matter of great concern to operators and maintenance personnel. The retained capacity of individual batteries is lower than the critical capacity, or some outdated batteries are mixed in the battery pack, which cannot output enough power under ignition conditions, which will directly affect normal transportation and production. Therefore, when the battery is overhauled, the firs...
