Embodiment 1

[0052] Please refer to figure 1 , figure 1 The schematic diagram of the charge-discharge program curve for internalization of raw plates provided for the specific implementation of the present invention, taking a 12V100Ah storage battery as an example:

[0053] When the ambient temperature is higher than 10°C to 30°C, the charging power MC is 3.0C, and the charging time in stage A is t 1 Take 9h, the charging time of stage B is t 2 Taking 3h, the charging time of stage C is 9h, the total charging time is 21h, and the charging current NC of stage A is 0.05C, that is, 0.05×100=5A, then

[0054] 21×0.05C+2×(x+2x+3x+4x+5x+6x+7x+8x)+3×9x=3C

[0055] Get x=0.02C=2A,

[0056] Then the charging procedure formed in the storage battery is:

[0057] charging time

[0058] At the same time, from the 10.5h to the 21st hour, discharge for 1 minute every 0.5h.

Embodiment 2

[0060] Take the 12V100Ah battery as an example:

[0061] When the ambient temperature is lower than 10°C to below 0°C, the charging power MC is 3.5C, and the charging time in stage A is t 1 Take 9h, the charging time of stage B is t 2 Taking 3h, the charging time of stage C is 9h, the total charging time is 21h, and the charging current NC of stage A is 0.05C, that is, 0.05×100=5A, then

[0062] 21×0.05C+2×(x+2x+3x+4x+5x+6x+7x+8x)+3×9x=3.5C

[0063] Get x=0.025C=2.5A,

[0064] Then the charging procedure formed in the storage battery is:

Abstract

The invention provides a charge and discharge method for the container formation of green accumulator plates. The charge and discharge method is characterized in that: the charge and discharge method includes the following steps that: charging is carried out for 8 to 10 hours at the stage A, the initial charging current is NC, and the current is increased by x each hour; charging is carried out for 3 to 4 hours at the stage B, the charging current is kept at the maximum charging current at the stage A, and discharging is started after 0.5 hours of charging and carried out for one time every 0.5 hours; the charging time at the stage C is equal to the charging time at the stage A, the current is decreased by x each hour, and discharging is carried out for one time every 0.5 hours from the beginning of charging to the last hour of charging; and the value of x is determined by the following formula: T multiplied by NC added with 2 multiplied by [x added with 2x added with 3x added with 4x added with 5x added with 6x added with 7x added with ... added with (t1 minus 1) x] added with t2 multiplied by t1x equal to MC. The charge and discharge method accords with the charge and discharge characteristics of the green accumulator plates, the charge current is always within the acceptable range of an accumulator, moreover, discharging is carried out timely, so that the polarization voltage can be quickly and effectively eliminated, the charging speed is high, and the formation time is short.

Description

technical field [0001] The invention relates to the field of storage battery formation, in particular to an internal formation process of storage battery raw plates. Background technique [0002] Lead-acid batteries are an important power source for battery electric vehicles, hybrid electric vehicles and fuel cell electric vehicles. In the manufacturing process of the battery, it is necessary to activate the positive and negative materials inside the plate through a certain charging and discharging method, and transform it into a state of charge, so as to improve the charging and discharging performance, self-discharging, storage and other comprehensive performance of the battery. This chemical reaction process is called For the formation process, the formation process is one of the important processes in battery production. [0003] Generally, there are two main formation methods for storage batteries. One is plate formation, which is to insert the raw plate into the forma...
