Intelligent charge control system for lead-acid battery

Abstract

The invention provides an intelligent charge control system for a lead-acid battery. The intelligent charge control system comprises a charger, and a lead-acid battery module capable of carrying out data communication with the charger, wherein the lead-acid battery module comprises a lead-acid battery pack and a battery management circuit; the battery management circuit is connected with the lead-acid battery pack and the charger respectively, and comprises a switch module, a battery management module and a communication module; before charge is started, the battery management circuit is used for receiving the charger identification code information sent by the charger, judging whether the charger identification code information is matched with the internal battery identification code thereof, and if the identification codes are successfully matched, conducting the switch module. By adopting the technical scheme of the invention, and internally arranging the battery management circuit in the lead-acid battery pack, the lead-acid battery can be protected better; meanwhile, the data communication is established between the charger and the battery management circuit, and normal charge between the charger and the lead-acid battery can be carried out only in case of matching, thus preventing damages to the lead-acid battery due to the mismatching of parameters; meanwhile, the charge process can be accurately controlled due to information communication between the charger and the battery, thus much reasonably charging the lead-acid battery.

Description

technical field [0001] The invention relates to a charge control system for a lead-acid battery, in particular to an intelligent charge control system for a lead-acid battery with a data communication function. Background technique [0002] At present, more and more products use lead-acid batteries as power sources, but in such products, the battery is often the most easily damaged component, which seriously affects the use of users. One of the important reasons for the short service life of lead-acid batteries is that the parameters between the charger and the battery do not match during the charging process of the lead-acid battery, which leads to sulfuration and outgassing of the lead-acid battery, which leads to a sharp decline in the capacity of the lead-acid battery. For example, in the existing battery car charger market, the manufacturers are chaotic and the product quality is uneven.

[0002] At present, more and more products use lead-acid batteries as power sources, but in such products, the battery is often the most easily damaged part, which seriously affects the use of users.

One of the important reasons for the short service life of lead-acid batteries is that the parameters of the lead-acid battery do not match between the charger and the battery during the charging process, which leads to sulfuration and outgassing of the lead-acid battery, resulting in a sharp drop in the capacity of the lead-acid battery

For example, in the existing battery car charger market, the manufacturers are chaotic and the product quality is uneven. Long-term use of low-quality chargers or charging under the condition that the charging parameters do not match will cause damage to the lead-acid battery and even cause battery explosion. wait for danger

[0003] In the existing technology, there is no information communication between the charger and the lead-acid battery, so it is impossible to match the charging parameters and accurately control the charging process, so that the battery is charged under the condition of mismatching parameters for a long time

And the existing lead-acid lead-acid batteries generally do not have a special charge protection circuit
