Patent description:

The invention relates to the field of charging, in particular to a linear lithium ion battery charging management chip. The voltage monitoring module is used for acquiring the terminal voltage of the battery, the instantaneous change rate of the terminal voltage of the battery and the average change rate of the terminal voltage of the battery in real time. The temperature monitoring module is used for acquiring the junction temperature and the junction temperature change rate of the chip in real time. The charging current management module is respectively connected with the voltage monitoring module, the temperature monitoring module and the charging time management module, and is used for acquiring the charging current according to the terminal voltage of the battery to be charged and the junction temperature of the chip. The charging time management module is used for acquiring the charging current interruption time.

According to the invention, the electric quantity and the use state of the battery can be obtained in real time, and then an appropriate initial current can be obtained to avoid overcharge damage to the battery caused by excessively high initial current, and the charging amount of the battery in a working state is prevented from being less than the discharging amount.
