The charging amount of the battery can be controlled, the efficiency is high, the heat consumption is low, and the equalization time is short.

Description

technical field [0001] The invention relates to the related field of battery charging, in particular to a management and control method, charger and system based on Android balanced charging. Background technique [0002] Balanced charging refers to the unbalanced voltage of the battery terminals due to individual differences and temperature differences of the battery during the use of the battery. In order to avoid the deterioration of this unbalanced trend, it is necessary to increase the charging voltage of the battery pack and activate the battery. Charging, in order to balance the characteristics of each battery in the lithium battery pack, the current existing technology is balanced charging in the battery pack, using a passive balancing method, using resistors to consume the energy of high-voltage or high-charge cells to achieve different The energy consumption of the cells is balanced, and the passive balance can only perform charge balance, but cannot perform discha...

AI Technical Summary

Problems solved by technology

This method is simple, but it will cause energy loss, so it is not suitable for fast charging system

[0005] 2. When lithium batteries are charged and discharged in balance: there is no lithium battery pack with a discharge capacity of 100%. Ensure that all small lithium batteries can reach full discharge at the same time

[0007] 4. The intelligent balance charger mainly solves the problem of battery balance charging technology. Generally, batteries are strictly prohibited from overcharging, and the electrochemical characteristics of batteries will deviate during long-term charging. Moreover, the current technology to achieve balanced charging is only controlled by a single-chip microcomputer system. The difference is to achieve on-off on the shunt resistor on the battery to control the charge of the battery. This method has complex control, low efficiency, large heat consumption, and long equalization time.
