An Acid Adding Charging Process for Reducing Charging Energy Consumption

Abstract

The invention provides an acid-adding charging process that reduces charging energy consumption. By improving the existing charging process, the density of the acid-added electrolyte in the battery is increased, and a charging process mode and a current time distribution method are used to ensure the formation of the polar plate. In the case of the effect and battery capacity, the charging energy consumption is greatly reduced, the process time is reduced to 47h, and the charging rate is 7.5 times, which saves 13.8% of energy consumption compared with the current process of 8.7 times, and solves the problem of high energy consumption of the current process.

Description

technical field [0001] The invention relates to the field of battery manufacturing, in particular to an acid-added charging process for reducing charging energy consumption. Background technique [0002] At present, in the field of battery manufacturing, it is very common to use the internalization charging process to charge the battery. At present, the internalization charging process of the battery generally takes a long time, and if the charging rate is low, it will As a result, the formation of the polar plate is not transparent, and the capacity is low, which cannot meet the factory requirements. Therefore, the charging rate of the current mainstream power battery formation process is about 9.5 times, and some low-energy-consumption processes can be reduced by less than 9.0 times. However, the energy consumption of the above-mentioned process is relatively large, and the production cost is relatively high. Therefore, it is particularly important to solve the problem of...

[0002] At present, in the field of storage battery manufacturing, it is very common to use the internalization charging process to charge the battery. However, it usually takes a long time to charge the battery with the internalization charging process, and if the charging rate is low, it will be As a result, the plate formation is impermeable, the capacity is low, and it cannot meet the factory requirements. Therefore, the charging rate of the current mainstream power battery formation process is about 9.5 times, and some low-energy-consumption processes can be reduced by less than 9.0 times.

However, the energy consumption of the above-mentioned process is relatively large, and the production cost is relatively high.
