Abstract

The invention provides a chip architecture for the intelligent management of a lead-acid storage battery. The chip architecture comprises a CAN bus which is connected to a lead-acid storage battery ina battery pack to collect a total voltage of the battery pack, an analog-to-digital conversion unit for collecting a terminal voltage of the lead-acid storage battery, a voltage conversion unit for converting a DC voltage to a rated voltage for power supply, a processor for obtaining a corresponding open circuit voltage according to the terminal voltage of the lead-acid storage battery and obtainan SOC value of a current lead-acid storage battery by using an SOC lookup table with the reference of the total voltage of the battery pack, a target equalization voltage and an SOC temperature correction coefficient, a voltage equalization control system used for judging whether the terminal voltage of the lead-acid storage battery is greater than the target equalization voltage, discharging byusing an operation mode until the voltage satisfies the target equalization voltage when the terminal voltage is greater than the target equalization voltage, and increasing the charging current of the target equalization voltage until the voltage satisfies the target equalization voltage when the terminal voltage is smaller than the target equalization voltage.

Description

technical field [0001] The invention relates to the technical field of battery processing, in particular to a chip architecture for intelligent management of lead-acid batteries. Background technique [0002] In the field of lead-acid batteries, to calculate the parameters of a single lead-acid battery, it is often necessary to use a variety of instruments to measure separately, and the parameters of the lead-acid battery (such as power, voltage, health status, etc.) can finally be obtained through the combined measurement of multiple instruments. At the same time, The inconsistency of each battery cell during use, if not controlled, will have a certain impact or even danger on the use of the battery, its impact is mainly reflected in the following aspects: (1) Due to the battery pack connected in series It is charged and discharged at the same time. During the charging process, the battery with low capacity must be fully charged first. For the sake of battery life and safe...
