Description

Quick charging method of lead-acid storage battery
Technical Field
The invention belongs to the field of charging of lead-acid storage batteries, and particularly relates to a quick charging method of a lead-acid storage battery.
Background
The life of a lead-acid battery is often considered to be a function of materials and design parameters such as grid alloy and thickness, composition of the lead paste, plate thickness, positive and negative active material ratios, electrolyte concentration, and discharge rate and depth of discharge. Although it is known that the charging mode has a significant effect on the life of the storage battery, unfortunately, in recent decades, the standard charging mode has hardly changed, i.e., a two-stage constant-current method or a combined constant-voltage and constant-current charging method is adopted. The main problems of the method are that the phenomenon of serious insufficient charge exists along with the aging of the battery and the reduction of the saturation of the electrolyte, and the phenomenon of thermal runaway is easily caused by not limiting the voltage in the last stage, so that the battery is prematurely failed, and the service life is obviously influenced.
Disclosure of Invention
Aiming at the defects in the prior art, the invention provides a quick charging method of a lead-acid storage battery.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a method for rapid charging of lead-acid batteries, comprising the following phases:
the first stage is as follows: 0.3C for lead-acid storage battery10Charging current of (2), when the average voltage of each battery reaches 2.5V, the charging current is halved to 0.15C10A, entering a second stage;
and a second stage: using 0.15C10The charging current A ensures that the average voltage of each battery reaches 2.6255 volts, or the charging current is halved to 0.075C when the voltage is not 2.6255 volts after the charging time reaches 1 hour10A, entering a third stage;
and a third stage: using 0.075C10Charging current A enables the average voltage of each battery to reach 2.7 volts, recharging is carried out for 30 minutes, and charging is finished; if the charging time is 1 hour and 30 minutes, the average voltage of each battery is less than 2.7 volts, and the charging is also finished.
Has the advantages that: the rapid charging method of the lead-acid storage battery provided by the invention can greatly shorten the charging time of the lead-acid storage battery under the condition of not damaging the service life of the lead-acid storage battery. The normal lead-acid storage battery is charged by using 0.1C10Under the condition of the current of A capacity, the lead-acid storage battery is fully charged in 12-16 hours generally. The invention uses 3 times of normal charging current, namely 0.3C10The current of the A capacity is charged, so that the charging time is shortened to be within 5 hours. If the discharge capacity is 80%; the mixture can be filled after 4 hours and half an hour.
Detailed Description
The invention is illustrated below with reference to specific examples. It will be understood by those skilled in the art that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention in any way.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a method for rapid charging of lead-acid batteries, comprising the following phases:
the first stage is as follows: 0.3C for lead-acid storage battery10Charging current of (2), when the average voltage of each battery reaches 2.5V, the charging current is halved to 0.15C10A, entering a second stage;
and a second stage: using 0.15C10The charging current A ensures that the average voltage of each battery reaches 2.6255 volts, or the charging current is halved to 0.075C when the voltage is not 2.6255 volts after the charging time reaches 1 hour10A, entering a third stage;
and a third stage: using 0.075C10Charging current A makes the average voltage of each battery reach 2.7 volts, recharging is carried out for 30 minutes, and charging is finished; if the charging time is 1 hour and 30 minutes, the average voltage of each battery is less than 2.7 volts, and the charging is also finishedAnd (4) bundling.
Finally, it is to be noted that the charging device made of any device, as long as the charging method disclosed in the present patent is adopted, is included in the present patent; if the charging method is used, the charging mode is considered to be equivalently adopted no matter three stages, four stages or more are adopted; the magnitude of the charging current is only required to be larger than 0.2C initially10The charging current and the voltage control point with the average voltage of each battery larger than 2.4 volts are adopted in the charging process, and the charging current is gradually reduced after the voltage control point is reached, so that the temperature rise of the lead-acid storage battery is reduced. The charging mode is adopted; the criterion of charging and the criterion of charging end of old lead-acid storage battery added with time control are the same as the charging mode.
