Embodiment 1

[0052] In order to solve the problem of inconvenient use of new energy vehicles and trailer vehicles in the prior art when they go out to play, embodiments of the present invention provide a charging and discharging control method for new energy vehicles and trailer vehicles.

[0053] refer to figure 1 , In this specific embodiment, a trailer vehicle is towed behind the new energy vehicle, and the battery system of the new energy vehicle is electrically connected to the battery system of the trailer vehicle. With such an arrangement, the battery system of the new energy vehicle is electrically connected with the battery system of the towed vehicle, so that the battery systems of the new energy vehicle and the towed vehicle can transmit power to each other, so as to meet the requirements of the new energy vehicle and the towed vehicle in the Electricity demand in different scenarios.

[0054] Further, in the charging and discharging control method for the new energy vehicle an...

Embodiment 2

[0093] Based on the charging and discharging control method for a new energy vehicle and a trailer vehicle provided by the above embodiments, this embodiment further provides another charging and discharging control method for a new energy vehicle and a trailer vehicle.

[0094] The difference between the charging and discharging control method for a new energy vehicle and a trailer vehicle provided in this embodiment and the above embodiment is only that in step S2, after it is determined that the new energy vehicle and the trailer vehicle are currently in the charging state, if the charging power supply When connected to a trailer vehicle, the power of the control charging power source is preferentially used to meet the power demand of the electrical equipment, and part of the remaining power is used to meet the charging demand of the second battery, and the other part is transferred to the new energy vehicle to meet the power demand. The charging requirement of the first bat...

Embodiment 3

[0097] Based on the charging and discharging control method for a new energy vehicle and a trailer vehicle provided by the above embodiments, this embodiment further provides another charging and discharging control method for a new energy vehicle and a trailer vehicle.

[0098] The difference between the charging and discharging control method for a new energy vehicle and a trailer vehicle provided in this embodiment and the above embodiment is only that in step S2, after it is determined that the new energy vehicle and the trailer vehicle are currently in the charging state, if the charging power supply When connected to a new energy vehicle and a trailer vehicle, the power of the charging power source is controlled to meet the electricity demand and / or charging demand of the trailer vehicle and the new energy vehicle, respectively.

[0099] That is to say, in the charging state, when both the new energy vehicle and the towed vehicle are plugged into the charging power supply...

Abstract

The invention provides a charging and discharging control method for a new energy vehicle and a trailer, a vehicle control unit and a vehicle. A trailer is towed behind the new energy vehicle, and a battery system of the new energy vehicle is electrically connected with a battery system of the trailer. The charging and discharging control method comprises the steps that whether the new energy vehicle and the trailer are in a driving state or not is judged; if yes, when the remaining electric quantity of the new energy vehicle is smaller than a preset first electric quantity threshold value, a battery system of the trailer is controlled to transmit electric energy to a battery system of the new energy vehicle; if not, whether the new energy vehicle and the trailer are in a charging state or not is judged; if yes, electric quantity transmission input by the charging power source is controlled according to the remaining electric quantity of the new energy vehicle and the trailer; if not, electric quantity transmission of a battery system of the new energy vehicle is controlled according to the remaining electric quantity of the trailer. According to the scheme, the endurance mileage of the vehicle can be prolonged, and the use convenience of the electric equipment for towing the vehicle is improved.

Description

technical field [0001] The invention relates to the technical field of charging and discharging of electric vehicles, in particular to a charging and discharging control method for a new energy vehicle and a trailer vehicle, a vehicle controller and a vehicle. Background technique [0002] Now with the improvement of people's life, the way of life is more and more colorful. Many vehicles have a trailer feature. In addition, new energy vehicles are becoming more and more popular. However, due to low battery density and imperfect charging facilities, current new energy vehicles will experience many inconveniences during long-distance travel or play. Camping has become a popular form of entertainment. If a new energy vehicle is used to tow a trailer, the cruising range of the new energy vehicle will be lower. For some trailers with smaller batteries and larger trailer weights New energy vehicles may even be completely unusable. [0003] In addition, most of the trailer vehi...
