Embodiment Construction
[0037] The present invention will be further described in detail below in conjunction with specific embodiments, which are explanations of the present invention rather than limitations.
[0038] A computing system for power consumption per unit time of a pure electric vehicle, including a vehicle ECU, a vehicle CAN bus, a battery management system and a liquid crystal display;
[0039] Vehicle CAN bus, used to transmit the vehicle speed to the vehicle ECU;
[0040] The battery management system is used to transmit the power consumption ΔQ of the vehicle driving Δt time to the on-board ECU;
[0041] The on-board ECU is used to divide the vehicle speed range into multiple speed gradients, and calculate and store the cumulative vehicle power consumption and power consumption time under different speed gradients; receive the vehicle speed transmitted by the vehicle CAN bus, and judge the The driving speed gradient to which the vehicle driving speed belongs, obtains the power cons...
