Embodiment 1

[0035] The vehicle power battery pack control system provided in Embodiment 1 collects battery monitoring parameters and charge and discharge state parameters from the control unit 102 for each unit battery pack, and through data interaction between the main control unit 101 and the vehicle management system 100, And the master control unit 101 allocates data to each slave control unit 102 to instruct the slave control unit 102 to control the charge and discharge of the battery pack. Based on this, the fine-grained control of each unit battery pack of the power battery pack is realized, and the performance of each unit battery pack is maintained to prevent battery abnormalities in the power battery pack and improve the driving safety of electric vehicles.

[0036] In the second embodiment, if figure 2 As shown, it is a module structure diagram of the vehicle power battery pack control system in Embodiment 2, and each slave control unit 102 includes one or more basic control u...

Embodiment 2

[0044] The vehicle power battery pack control system provided in the second embodiment collects battery monitoring parameters and charge and discharge state parameters for each unit battery through the basic control unit 201, and through data interaction between the main control unit 101 and the vehicle management system, and through The master control unit 101 allocates data to each slave control unit 102 , and instructs the basic control unit 201 to control the charge and discharge of the unit cells through the slave control unit 102 . Based on this, the fine-grained control of each unit battery in the power battery pack is further realized, and the performance of each unit battery is maintained to prevent battery abnormalities in the power battery pack and further improve the driving safety of electric vehicles.

[0045]In the third embodiment, such as image 3 As shown, it is a module structure diagram of the vehicle power battery pack control system in Embodiment 3, which...

Embodiment 3

[0049] The vehicle power battery pack control system provided in the third embodiment uses the battery balancing unit 301 to balance the power of each unit battery so that the power of each unit battery converges to the preset average power value. Based on this, while controlling the charge and discharge of each unit battery pack, the battery performance of the unit battery pack is unified through balance control, further preventing battery abnormalities in the power battery pack, and improving the driving safety of electric vehicles.

[0050] In Example 4, as Figure 4 As shown, it is a module structure diagram of the vehicle power battery pack control system in Embodiment 4, which also includes a temperature control unit 401;

[0051] Each temperature control unit 401 is respectively connected to a corresponding slave control unit and a corresponding battery pack.

[0052] Wherein, the temperature control unit 401 is used to control the temperature of the correspondingly co...

Abstract

The invention provides a vehicular power battery pack control system and method. Battery monitoring parameters and charge-discharge state parameters of a unit battery pack are acquired by a slave control unit; the battery monitoring parameters and the charge-discharge state parameters are transmitted to a vehicle management system through a master control unit; a battery control command fed back by the vehicle management system is received; charge-discharge state control is performed on the corresponding unit battery pack according to the battery control command. On such basis, unit battery packs are monitored in real time during service of an electric vehicle; dynamic charge-discharge control is performed on the unit battery packs according to the battery monitoring parameters and charge-discharge state parameters; therefore, anomalies of power battery packs are prevented, and driving safety of the electric vehicle is guaranteed.

Description

technical field [0001] The invention relates to the technical field of battery management, in particular to a vehicle power battery pack control system and a control method thereof. Background technique [0002] With the development of new energy vehicles, electric vehicles such as electric cars and electric buses are becoming more and more popular. Among them, the main power source of the electric vehicle is the power battery pack on the vehicle. During the use of the electric vehicle, the power battery pack needs to carry out different types of charging and discharging in conjunction with the use of the electric vehicle, resulting in relatively large fluctuations in the parameters of the power battery pack. Large, prone to battery abnormalities, affecting the safe driving of electric vehicles. Contents of the invention [0003] Based on this, it is necessary to provide a vehicle power battery pack control system and a control method thereof for power battery packs that ...
