Abstract

The invention relates to an intelligent balancing management system for batteries and belongs to the technical field of electric vehicles. The balancing management system comprises a voltage collecting system, a matrix switch and a single battery pack and further comprises a standby energy storage battery, a main control unit, an execution module and a direct current (DC)-DC converter. The standby energy storage battery is respectively connected with the matrix switch and the DC-DC converter; the voltage collecting system is respectively connected with the main control unit, the matrix switch and the single battery pack; the main control unit is connected with the matrix switch through the execution module and is connected with the standby energy storage battery through the DC-DC converter; and the matrix switch is connected with the single battery pack. The intelligent balancing management system can effectively solve the problem of over charging and over discharging which are caused by consistency between single batteries, functions of the intelligent balancing management system comprise balance during a charging period and balance during a discharging period, an energy cycle complementary charging and discharging mode is adopted, and the whole system is safe and reliable, effectively improves performance of the battery pack and prolongs service life of the battery pack.

Description

technical field [0001] The invention belongs to the technical field of electric vehicles, and in particular relates to the use technology of a power battery. By using the equalization system to balance the power supply system, the energy efficiency of the battery can be effectively brought into play, the mileage of the battery can be extended, the life of the battery can be extended, and the use safety can be extended. Background technique [0002] In recent years, many scholars at home and abroad have conducted a lot of research on the balance control problem of multi-cell power batteries in series and proposed various solutions. There are various defects in the common balance control strategy, such as the passive balance method that has been widely used in the lithium battery management system. Such as figure 1 As shown, several single cells 15 are connected in series with connectors 14 to form a battery pack with required voltage. A wire is drawn from the positive pole ...
