Abstract

The invention provides a battery pre-charging method comprising the following steps that the battery voltage is detected; whether the battery voltage is greater than the first preset voltage is judged, and a calculation instruction is transmitted when the battery voltage is not greater than the first preset voltage; the difference value between the battery voltage and the first preset voltage is calculated according to the calculation instruction; whether the absolute value of the difference value is less than the preset value is judged, and a pre-charging instruction is transmitted when the absolute value of the difference value is less than the preset value; the pre-charging instruction is used for performing virtual voltage charging to the battery; the real-time voltage of the battery after virtual voltage charging is detected whether the real-time voltage is greater than the second preset voltage is judged, and a charging instruction is transmitted when the real-time voltage is greater than the second preset voltage; and normal charging of the battery is started according to the charging instruction. The battery pre-charging method has high reliability. The invention also provides a battery pre-charging device.

Description

【Technical field】 [0001] The invention relates to the technical field of battery precharging, in particular to a battery precharging device and method. 【Background technique】 [0002] In the production process of lithium batteries, the battery needs to be dried, statically polarized and precharged. After the battery is statically polarized, it will generate voltage, and then use the precharging cabinet to precharge the battery. Before precharging, the voltage of the battery needs to be detected. , if the battery voltage is lower than the preset voltage, the battery will not be charged. However, due to the different materials used for battery production and the complexity of the processing technology, some good batteries with lower voltages will not be able to be charged. [0003] In view of this, it is necessary to provide a new battery pre-charging device and method to overcome the above-mentioned defects. 【Content of invention】 [0004] The purpose of the present inven...
