Problems solved by technology
Due to constant voltage charging, regardless of the actual state of the battery voltage, the charging voltage is always constant. If the charging voltage is too low, it will prolong the charging time and affect the charging efficiency. battery damage
At present, many chargers have adopted the multi-charging stage charging method. This method has the characteristics of short charging time and good charging effect. However, how to combine solar cells with chargers to realize multi-charging stage cyclic charging technology is still to be explored. middle

The invention relates to the technical field of charging of a lead-acid storage battery, in particular to a quick charger of the lead-acid storage battery for a multi-charging stage in which solar energy is used as a power supply. The charger is formed by connecting a solar battery, a main control chip module, a control execution circuit module, a voltage detection module and a charging indication module. The charger is characterized in that: a solar battery panel serves as a power supply circuit; the multi-charging stage of the lead-acid storage battery is realized by using the main control chip module and the control execution circuit module; and a charging mode of the multi-charging stage in which the solar energy is used as the power supply is realized by using the voltage detection module as a storage battery actual state information feedback circuit. The invention has the advantages that: the intelligent charging of the lead-acid storage battery is realized by using sufficient solar resources; the charger is low in charging cost, high in charging efficiency and high in degree of intelligence; and the service life of the lead-acid storage battery can be prolonged.
Description
technical field [0001] The invention relates to the technical field of charging lead-acid batteries, in particular to a fast charger for lead-acid batteries used in multi-charging stages using solar cells as power sources. Background technique [0002] At present, lead-acid battery is the main product of large-capacity battery. Due to its low manufacturing cost, large capacity and low price, it has been widely used in communication, transportation, electric power and other departments, and has become the main energy storage device of solar cells. . Although the price of lead-acid batteries is low, batteries damaged due to unreasonable charge and discharge control of batteries account for a considerable proportion, causing a lot of waste. [0003] At present, most lead-acid battery chargers still use the floating charge (constant voltage charge) charging method, however, there are some shortcomings in this method. Due to constant voltage charging, regardless of the actual s...
