Embodiment

[0035] Embodiment: a kind of power type lead-acid storage battery high temperature internalization method of the present embodiment, such as figure 1 shown, including the following steps:

[0036] S1: Add the sulfuric acid electrolyte to the lead-acid battery and let it stand for 0.2~0.5h, then start the charging procedure;

[0037] S2: High-temperature formation stage (no cooling water is added to the battery tank during the process), including the following steps:

[0038] S201: Charge with a constant current of 0.1~0.2I2 for 1~2 hours;

[0039] S202: Charge with a constant current of 0.3~0.5I2 for 3~4 hours;

[0040] S203: Charge with a constant current of 0.5~0.6I2 for 5~8 hours;

[0041] S3: normal temperature formation stage, including the following steps:

[0042] S301: Stand still for 0.5h after high-temperature charging;

[0043] S302: Charge with a constant current of 0.4~0.5I2 for 10~14 hours, and then stand still for 0.5 hours;

[0044] S303: Charge with a co...

Abstract

The invention discloses a high-temperature inner formation method of a power type lead-acid storage battery. The method includes steps of S1, adding sulfate electrolyte in the type lead-acid storage battery and then staying for 0.2-0.5 hour; starting a charging procedure; S2, high-temperature formation stage; S3, room-temperature formation stage; S4, after charging, pumping acid and finishing theformation. The method can guarantee the uniform formation of a positive plate of the lead-acid storage battery; the active matters of the type lead-acid storage battery are fully converted; the charging power amount before discharging a battery set is few and the formation charging time is short.

Description

technical field [0001] The invention relates to the technical field of power type lead-acid batteries, in particular to a high-temperature internalization method for power type lead-acid batteries. Background technique [0002] Lead-acid batteries have the characteristics of low price, convenient use and stable performance, and have been widely used in various fields. At present, they have a large market share, especially in electric bicycles. With the rise of other new energy battery technologies and changes in the market environment, higher requirements are placed on the cycle life of lead-acid batteries, and industry technicians have been working hard to improve them. [0003] It is undoubtedly a major breakthrough direction to improve its technology in the process stage. Its production process mainly consists of lead powder manufacturing, grid manufacturing, lead paste mixing, plate coating, plate curing and drying, plate formation and battery assembly. Among the above...
