Abstract

The invention relates to a power battery technology. One embodiment of the invention provides an adaptive charging control device for a power battery based on battery aging. The device comprises a charging target determination unit, a control parameter determination unit and a charging completion determination unit, wherein the charging target determination unit is configured to determine a current charging target SOC based on the current battery capacity of the power battery; the control parameter determination unit is configured to determine the current charging target voltage and the current charging cutoff current based on the current charging target SOC; and the charging completion determination unit is configured to determine that the current charging of the power battery is completed based on the current charging target voltage and the current charging cutoff current. The device can adaptively adjust the charging completion control parameters according to the continuous change of the aging state of the battery so as to achieve the high-precision control of the SOC when the charging of the power battery is completed.

Description

technical field [0001] The present invention generally relates to power battery technology, and more particularly, relates to a power battery self-adaptive charging control method and device based on battery aging. Background technique [0002] With the depletion of petroleum resources around the world, new energy vehicles, as a substitute for traditional energy vehicles, are increasingly being valued by human beings. Power batteries (such as high-voltage battery packs) are important energy components for new energy vehicles, especially electric vehicles. At present, one of the main power batteries is a lithium battery, which has the characteristics of high energy density, no pollution, and no memory effect, so it is widely used in new energy vehicles. [0003] An important parameter of the power battery is the state of charge (State of Charge, "SOC"), also known as the remaining capacity, which represents the ratio of the remaining capacity of the battery to the capacity o...
