Problems solved by technology

However, after the electric energy passes through the high-voltage cell, then through the capacitor or inductance or DC / DC, and then to the low-voltage cell, there are two electric energy conversions in the middle, resulting in more energy conversion losses

Abstract

Provided in embodiments of the present invention are a charging control method, system, charger, smart battery, and movable platform. The method comprises: during a process of charging a battery, determining, according to detected voltages of N battery cells, M battery cells requiring passive equalization; and discharging the M battery cells, such that the N battery cells reach an equalized stateduring the charging process. An equalized state is achieved for the battery cells, thus improving an available capacity of the battery. In addition, the present embodiment eliminates the need to perform electrical energy transfer in the prior art, and performs discharging directly on the M battery cells, thus preventing losses during energy transfer, and enhancing stability of an equalization process.

Description

technical field [0001] The embodiments of the present invention relate to the field of battery technology, and in particular, to a charging control method, system, charger, smart battery and mobile platform. Background technique [0002] In order to meet the power demand of the power system, the battery is often composed of cells connected in series. Each single cell has the highest safe voltage and the lowest safe voltage, if it exceeds, the cell will be damaged. Due to the imbalance between the cells, the usable capacity of the entire battery pack will be reduced. Therefore, it is very important to balance among multiple strings of cells. One of the current methods is to use capacitors, inductors, and DC / DC to transfer electric energy from high-voltage cells to low-voltage cells, so as to achieve voltage balance between cells. However, after the electric energy passes through the high-voltage cell, then through the capacitor or inductor or DC / DC, and then to the low-vol...
