In this paper, a new method of charging and repairing lead-acid batteries is proposed. Firstly, small pulse current is used to activate and protect the batteries in the initial stage; when the current approaches the optimal current curve, the phase constant current charging is used instead, when the voltage is low.
Sci.859 012083DOI 10.1088/1755-1315/859/1/012083 Lead-acid batteries are widely used due to their many advantages and have a high market share. However, the failure of lead-acid batteries is also a hot issue that attracts attention.
The crystallized lead sulfate not only does not participate in the reaction, but also adsorbs on the surface of the electrode plate, which increases the internal resistance of the battery and affects the charge and discharge performance of the battery and the battery capacity3.
Lead-acid batteries have the advantages of working under high-current discharge conditions, abundant and easily available raw materials, low price, high reliability, and wide working range. Therefore, since its inception, they have been widely used in transportation, communications, electricity, high-tech weapons and other fields.
With the rapid development of China's electric vehicle industry, the demand for vehicle-mounted lead-acid batteries is increasing, and higher requirements are put forward for their safety and reliability. There are some problems in lead-acid batteries, such as short service life and decreasing capacity.
Physical repair methods are usually used, including positive and negative pulse repair technology, high-frequency resonance repair and scanning resonance frequency technology. This kind of repair method has the advantages of low cost, easy to operate, and does not change the internal structure of the battery.
