Description
Technical Field
The invention relates to the field related to battery charging, in particular to a management and control method, a charger and a system based on android balance charging.
Background
The balance charging means that the terminal voltages of the batteries are unbalanced due to individual differences, temperature differences, etc. of the batteries during the use of the batteries, and in order to avoid worsening of such unbalanced tendency, it is necessary to increase the charging voltage of the battery pack, the battery is activated and charged to balance the characteristics of each battery in the lithium battery pack, the prior art adopts a passive equalization mode to charge the battery pack in an equalization mode, a resistor is used to consume the energy of a high-voltage or high-charge electric core so as to balance the energy consumption of different electric cores, while the passive equalization can only perform charge equalization and can not perform discharge equalization, when the discharge of the minimum-capacity battery is finished, the discharge of the battery pack is finished, even if other batteries have a lot of residual capacity and do not play any role, the larger the difference of the batteries is, the more serious the problem of capacity waste is, and the more serious the problem of shrinkage of endurance mileage is.
There are four types of balance charging:
1. the quick charging capability is strong: the active balancing function can enable each small battery in the battery pack to achieve balance more quickly, so that the safety of quick charging is higher, the targeted customized development is needed, and the active balancing function is also suitable for a high-rate charging mode with larger current. Each single battery of the lithium battery pack is additionally provided with a parallel balancing circuit to achieve the effect of shunting. In this mode, when a battery first reaches full charge, the equalizing device can prevent its overcharge and convert the excess energy into heat energy to continue charging the battery that is not fully charged. The method is simple, but can bring energy loss, and is not suitable for a quick charging system.
2. When the lithium battery is charged and discharged in a balanced manner: there is no lithium battery pack with a discharge capacity of 100%, because the end of the working capacity of a group of lithium batteries is determined by a certain small lithium battery which is discharged first, and it cannot be guaranteed that all the small lithium batteries can reach the discharge capacity at the same time. In contrast, there are individual small lithium batteries that retain unused residual electrical power.
3. The system performance employed by the active balancing method depends on the ratio between the balancing current and the battery charge/discharge efficiency. The higher the imbalance rate of a group of lithium batteries, or the greater the battery charging/discharging rate, the higher the balance current required will naturally be. And timing, sequencing, and individually detecting and uniformly charging the single batteries in the lithium battery pack. When the lithium battery pack is charged, each lithium battery in the battery pack can be ensured not to be overcharged or overdischarged, so that each battery in the lithium battery pack is ensured to be in a normal working state.
4. The intelligent balance charger mainly solves the technical problem of balance charging of batteries, generally, the batteries are strictly forbidden to be overcharged, the electrochemical characteristics of the batteries can deviate in the long-term charging process, and the existing technology for realizing balance charging only adopts a singlechip system to control the on-off of a shunt resistor on the batteries, so that the charging quantity of the batteries is controlled, and the method has the advantages of complex control, low efficiency, high heat consumption and long balance time.
