Embodiment 1
[0053] like figure 1 The illustrated embodiment is a high-voltage power distribution device, which is installed on an electric vehicle, and the electric vehicle includes a power battery pack 7, a motor controller 8, an air conditioner 9, a start switch 16 and an emergency brake switch 17; A charger 2, a microprocessor 3, a current loop 4, a first relay 5, a second relay 6, a third relay 10 and a DC step-down device 11 connected to an AC power source 1; The microprocessor is electrically connected with the DC voltage reducer, the microprocessor is respectively connected with the first relay, the second relay, the third relay, the start switch, the emergency brake switch, the power battery pack and the current loop, the first relay, the power battery pack , the second relay, and the motor controller are electrically connected in sequence, the current loop is set on the wire connecting the first relay and the negative pole of the power battery pack, and the DC step-down device is...
Embodiment 2
[0073] Embodiment 2 comprises all structures and method parts in embodiment 1, as figure 1 As shown, Embodiment 2 also includes an alarm 12, a memory 13 and at least one temperature sensor 14 provided on the casing of the power battery pack. The alarm, memory and each temperature sensor are all electrically connected to the microprocessor. It also includes a fan 15 arranged on the electric vehicle for cooling the power battery pack, and the fan is electrically connected to the microprocessor. Also included is a display 18 which is electrically connected to the microprocessor.
[0074] Embodiment 2 also comprises the steps:
[0075] (6-1) The microprocessor reads the temperature signal u(t) detected by the temperature sensor, sets the initial value of j to 1, and sets the initial value of i to 1; a fault threshold E is set in the memory;
[0076] (6-2) Calculate the local maximum value of u(t) and obtain the upper envelope u through cubic spline interpolation up (t);
