Abstract

The invention discloses a rapid container formation charging method for a lead-acid storage battery. The charging method is implemented through 27 charging and discharging stages, including eight times of discharging, one time of standing and one time of capacity checking and matching, wherein a maximum charging current is 0.15C<3> to 0.20C<3>, and a minimum charging current is 0.01C<3> to 0.05C<3>. The lead-acid storage battery is charged and discharged repeatedly, and a quantity of electricity charged each time is larger than a quantity of electricity discharged subsequently. Through adoption of the method, concentration polarization phenomena can be reduced greatly, and damages to crystal structures of active substances on a pole plate are reduced, thereby prolonging the service lifecycle of the lead-acid storage battery. As indicated by a detection performed according to specifications in GB / T18332.1-2009, the service lifecycle of the lead-acid storage battery adopting the method is greater than 450 times, and an initial capacity of the lead-acid storage battery is not less than 100 percent (counted by a rated capacity)

Description

technical field [0001] The invention relates to a lead-acid storage battery, in particular to a fast internalization charging method for a lead-acid storage battery. Background technique [0002] Compared with external formation (tank formation), the internal formation of lead-acid batteries has many advantages. Its technological process simplifies the processes of plate washing, drying, battery replenishment, and tank formation, such as loading, welding, and sheet removal. It saves a lot of energy (pure water, acid, electricity and other energy), man-hours, occupies a small area, and does not need to purchase chemical formation tank equipment and acid mist prevention equipment, and the battery cost can be reduced to a certain extent. The plate is not easily polluted by impurities, which can reduce battery self-discharge, improve battery consistency, and prolong battery life. Moreover, the internal formation of batteries reduces the discharge of waste water and waste gas, t...
