Embodiment Construction

[0014] exist figure 1 Among them, the discharge battery pack (1) is connected in series with the supplementary pressure power supply (2) to charge the rechargeable battery pack (4). Simultaneously, the supplementary current power supply (3) also charges the rechargeable battery pack (4). The battery pack (4) can obtain the electric energy added by (3) and (1)(2). By adjusting the current of (2), the discharge current of (1) can be controlled according to the process design. Adjusting the current of (3) can control the charging current of (4). In order to meet the requirements of process design.

[0015] exist figure 2 In the 7-stage process embodiment shown, (2), (3), (9), and (10) are a group. (4), (5), (11), (12) are one group. (6), (7), (13), (14) are one group. form three groups of similar figure 1 The charging and discharging circuit of each power supply symbol is the charging and discharging current required by the process design.

Abstract

The invention discloses a lead-acid storage battery formation charging and discharging method which comprises the step of adopting a charging power supply for converting alternating current of a power grid into direct current to charge storage batteries. The method is designed according to multi-stage process of charging and discharging in formation, and the storage batteries are divided into groups with the number the same as the number of stages in the process. All the groups of storage batteries work in different stages in the process. The battery packs in the discharging stage are used for charging the battery packs in the charging stage. The capacity and energy consumption of power grid equipment, charging equipment and discharging equipment can be reduced. The lead-acid storage battery formation charging and discharging method aims at solving the requirement problem that the voltage and energy of the discharging battery packs are lower than those of the charging battery packs. A power supply is connected on each discharging battery pack in series for compensating the discharging voltage and controlling the discharging current. On the basis, a power supply is connected in parallel for compensating the charging current and controlling the charging current to meet the design requirement of the process.

Description

Technical field [0001] The present invention is applied to the method of charging and discharging the lead-acid storage battery multiple times before leaving the factory after the lead-acid storage battery is assembled. This kind of charging and discharging is called formation charging and discharging in the field of lead-acid battery manufacturing. Background technique [0002] At present, domestic lead-acid battery manufacturers adopt multi-channel, multi-group parallel charging and discharging methods for formation charging and discharging. It is to connect all the batteries that need to be charged and discharged through series and parallel circuits to form a large battery pack. Then use the public grid to charge with large charging equipment. After the first charge is completed, perform the discharge operation. The discharge method is to use low-frequency inverter equipment to invert the energy of the battery into the electric energy of the public grid, and send it ba...
