Embodiment Construction

[0033] Vehicle Example:

[0034] like figure 1 As shown, the vehicle includes a vehicle body and a vehicle electrical device energy consumption monitoring device. The vehicle body is provided with an MCU (motor controller), an air compressor controller, a steering controller, an air conditioner controller, and a DC / DC controller. The controller is also provided with an alarm module, the vehicle electrical device energy consumption monitoring device includes a processor and a memory, and various types of controllers, memory, and alarm modules are all connected to the processor.

[0035] In order to save the number of electrical devices in the vehicle, in this embodiment, the processor is a VCU (Vehicle Controller). As another implementation, an additional processor may be added to the vehicle.

[0036]Various types of controllers are used to control the corresponding electrical devices to work. The memory stores the energy consumption data of each electrical device calibrated ...

Abstract

The invention relates to a method and device for monitoring energy consumption of a vehicle and its electrical components. The monitoring method includes the following steps: obtaining the working voltage and working current of at least two electrical components in the vehicle, and according to the working voltage and corresponding working voltage of each electrical component The actual energy consumption value of the corresponding electrical device is obtained by current calculation; the actual energy consumption value of each electrical device is compared with the calibrated energy consumption value of the corresponding electrical device, and the difference between the two is judged. Whether the energy consumption of electrical devices is abnormal. This method realizes the real-time monitoring of the energy consumption of each electrical component by directly obtaining the working current and working voltage of a single electrical component, and can also monitor the short-cycle energy consumption trend of the vehicle to truly reflect the energy consumption of each component of the vehicle , timely identify the electrical components with abnormal energy consumption through the energy consumption situation, and remind the staff to carry out maintenance before the relevant electrical components fail to ensure the functional safety of the vehicle.

Description

technical field [0001] The present invention relates to a method and device for monitoring the energy consumption of a vehicle and its electrical components. Background technique [0002] The rapid development of pure electric vehicles has made a large number of electric devices in electric vehicles widely used. These electric devices are all powered by batteries, and the energy consumption status of each electric device directly affects the drivable mileage of the vehicle. For vehicle manufacturers, under the current level of battery technology, ensuring that vehicle electrical components operate at an ideal energy consumption level and increasing drivable mileage is an important foothold to enhance their own competitive advantages. For vehicle operators , the good energy performance of electrical devices is also a very important aspect to reduce operating costs. Therefore, how to monitor and evaluate the energy consumption status of each electrical device in real time to ...
