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...
