Embodiment 1

[0031] Such as figure 1 As shown, the battery management system 10 provided in this embodiment includes: a central processing unit 100, a battery controller 120, and a network transceiver module 110. The network transceiver module 110 is arranged between the central processing unit 100 and the battery controller 120, and the central processing unit The processor includes processing chips MPC560xB, MPC5746R or MPC5744P.

[0032] The central processing unit is responsible for the information processing of the battery management system and coordinates the cooperation among various modules. The central processing unit 100 implements information transmission with the battery controller 120 through the network transceiver module 110 . The operation of the battery controller 120 on the battery requires the central processing unit 100 to send corresponding instructions through the network transceiver module 110 to start.

[0033] The processing chip MPC560xB, MPC5746R or MPC5744P ha...

Embodiment 2

[0035] On the basis of Embodiment 1, the central processing unit 100 of this embodiment further includes a charge and discharge management module, and the processing chip MPC560xB, MPC5746R or MPC5744P is connected to the battery controller through the charge and discharge management module. The charge and discharge management module includes a charge management unit and a discharge management unit. The processing chip MPC560xB, MPC5746R or MPC5744P realizes battery charging through the charge management unit, and realizes battery discharge through the discharge management unit, but all need the processing chip MPC560xB, MPC5746R or MPC5744P to pass through the network The transceiver module 110 sends corresponding instructions to the battery controller 120 . In the following, the processing chip MPC560xB is used as the processing chip MPC5602 for illustration.

[0036] Such as figure 2 As shown, the charging management unit includes: 1 MOS tube, 1 driver chip, 1 NPN transis...

Embodiment 3

[0041] Such as image 3 As shown, on the basis of the above embodiments, this embodiment provides that the battery controller in the battery management system includes an integrated circuit MC33771B and a first anti-jamming module, and the first anti-jamming module includes: 1 MOS tube, 2 resistors, 1 capacitor, wherein: one end of resistor R128 connected in series with capacitor C117 is grounded, the other end of resistor R128 connected in series with capacitor C117 is connected to the negative pole of battery BA14, one end of resistor R123 is connected to the positive pole of battery BA14, and resistor R123 is connected to the integrated The CT-1 port of the circuit MC33771B, the G pole of the MOS transistor Q32 is connected between the resistor R128 and the capacitor C117 and connected to the CB-1 port of the integrated circuit MC33771B, the S pole of the MOS transistor Q32 is connected to the negative pole of the resistor R128 and the power supply BA14 In between, the D po...

Description

technical field [0001] The present application relates to the technical field of electric vehicles, in particular to a battery management system and electric vehicles. Background technique [0002] With the development of electric vehicles, the mileage continues to increase, resulting in a continuous increase in the number of batteries installed in the car. In order to manage and control these batteries, a battery management system is usually set up to monitor and adjust these batteries. The battery management system is the core component of electric vehicles and an important indicator to ensure the performance of electric vehicles. [0003] The disadvantages are that the fault diagnosis of the battery in the traditional technology generally adopts online monitoring to poll and collect data, which does not have the ability of active coordination, and the network communication ability of the battery management system is poor, which affects the real-time reception of sending a...
