Catl publishes patents related to "fast battery charging", which can adjust the charging current in real time
According to the patent abstract, the application provides a fast battery charging method and a computer device. It includes establishing the negative potential estimation model and setting the negative potential safety threshold; adjusting the first preset charging current to the second preset charging current after charging the battery with the first preset charging current for a preset time; charging the battery with the second preset charging current for a constant current, and obtaining the negative potential estimation value of the battery in real time by using the negative potential estimation model during the charging process; When the estimated negative potential drops to the negative potential safety threshold, the second preset charging current is adjusted in real time to ensure that the difference between the estimated negative potential and the negative potential safety threshold is within the preset range, and the battery is charged with the adjusted current until the charging cut-off voltage.


It home learned that this method uses the relationship between the safety threshold of negative potential and the estimated value of negative potential to adjust the charging current in real time, so as to maximize the charging capacity of the battery within the safe range without lithium evolution side reaction, and realize the safe and rapid charging of the battery.
