Example Embodiment
[0027] Specific implementation mode 1: the following combination figure 1 To explain this embodiment, the electric vehicle power system of this embodiment includes a first energy unit 10, a diode 11, a second energy unit 12, a drive circuit 14, a motor 16, and a controller 20. It also includes a heating circuit 101, Temperature detection device 102 and temperature control device 103;
[0028] The first electrical signal output end of the first energy unit 10 is connected to the anode of the diode 11, the cathode of the diode 11 is connected to the first electrical signal output end of the second energy unit 12, and the first electrical signal output end of the second energy unit 12 is connected to the drive The first electrical signal input end of the circuit 14, the second electrical signal output end of the first energy unit 10, and the second electrical signal output end of the second energy unit 12 are simultaneously connected to the second electrical signal input end of the d...
Example Embodiment
[0041] Specific implementation manner 2: the following combination figure 2 To illustrate this embodiment, this embodiment will further illustrate the first embodiment. The first energy unit 10 is a lithium battery or a lithium battery pack, and the second energy unit 12 is a super capacitor or a super capacitor pack.
[0042] In this embodiment, the second energy unit 12 adopts a super capacitor or a super capacitor bank, and the controller 20 controls the bidirectional flow of energy between the second energy unit 12 and the motor 16. Specifically, when the electric vehicle is operating in an acceleration or uphill mode, the motor 16 works in an electric state, and the energy in the power system of the electric vehicle flows from the first energy unit 10 and the second energy unit 12 to the motor 16. When the electric vehicle works in the deceleration or downhill mode, the motor 16 works in a braking state, and the energy of the power system of the electric vehicle flows from t...
