Embodiment 1

[0044] figure 1 It is a flow chart of a vehicle energy recovery and distribution method provided by Embodiment 1 of the present invention. This embodiment is applicable to the case of energy recovery when an electric vehicle brakes. This method can be executed by a vehicle energy recovery and distribution device. The device Can be implemented by software and / or hardware.

[0045] Such as figure 1 As shown, the method specifically includes the following steps:

[0046] Step 110, when the vehicle brakes or coasts, acquires the recovered electric energy of the inter-wheel recovered electric energy.

[0047] Among them, the electric energy recovered between the wheels can be understood as the electric energy converted from the mechanical energy generated by the friction of the wheels when the car is braking or coasting. The recovered power can be understood as the energy value of the recovered power between wheels.

[0048] Specifically, when the vehicle is running, when the d...

Embodiment 2

[0054] figure 2 It is a flow chart of a vehicle energy recovery distribution method provided by Embodiment 2 of the present invention. On the basis of the above-mentioned embodiments, this embodiment further optimizes the above-mentioned vehicle energy recovery distribution method.

[0055] like figure 2 As shown, the method specifically includes:

[0056] Step 210, when the vehicle brakes or coasts, acquires the recovered electric energy of the inter-wheel recovered electric energy.

[0057] Specifically, when the vehicle is running, when the driver presses the brake pedal, or the vehicle is in a coasting state, the vehicle brake will convert the excess mechanical energy into electrical energy, and the inter-wheel regenerative electrical energy generated within a preset period of time can be obtained The recycled electricity is analyzed according to the value of the recycled electricity, so as to reasonably distribute the recovered electricity among the wheels.

Embodiment 3

[0080] The vehicle energy recovery and distribution device provided in the embodiments of the present invention can execute the vehicle energy recovery and distribution method provided in any embodiment of the present invention, and has corresponding functional modules and beneficial effects for executing the method. Figure 4 It is a structural block diagram of a vehicle energy recovery and distribution device provided in Embodiment 3 of the present invention, as shown in Figure 4 As shown, the device includes: a recovery power determination module 310 and a first energy distribution module 320 .

[0081] The recovered power determining module 310 is configured to acquire the recovered power of inter-wheel recovered electric energy when the vehicle brakes or coasts.

[0082] The first energy distribution module 320 is configured to adjust the battery target temperature according to the recovered electric power if the current ambient temperature is greater than the preset tem...

Abstract

The invention discloses a vehicle energy recovery and distribution method and device, a vehicle and a storage medium. The method comprises the steps that when a vehicle brakes or slides, the recovered electric quantity of inter-wheel recovered electric energy is obtained; and if the current environment temperature is higher than the preset temperature, the target temperature of the battery is adjusted according to the recycled electric quantity, so that the inter-wheel recycled electric energy is used for reducing the temperature of the cooling liquid. The problems that in existing vehicle braking energy recovery, energy forms are converted multiple times in the process of converting mechanical energy into electric energy, converting electric energy into chemical energy and converting chemical energy into electric energy again, and the energy recovery and utilization rate is low are solved, and vehicle braking recovered energy is directly used for vehicle refrigeration. The recycled energy is directly converted into cold energy when the environment temperature is high, and the energy conversion loss is reduced.

Description

technical field [0001] Embodiments of the present invention relate to the technical field of vehicle design, and in particular to a vehicle energy recovery distribution method, device, vehicle and storage medium. Background technique [0002] At present, the mileage of electric vehicles in the actual use of users is quite different from the announced mileage, resulting in poor car experience for consumers and many complaints. One of the main reasons is that the announced mileage is tested under relatively simple driving conditions. For example, the vehicle’s air-conditioning system is turned off during the test, but when the user actually uses the car, most of the time is If the air conditioner needs to be turned on, especially when the temperature of the outdoor environment is high, the cooling of the battery also needs to further consume power, resulting in attenuation of the driving range and causing user range anxiety. [0003] Generally speaking, whether it is air-cond...
