With the gradual popularization of new energy vehicles in recent years, more and more people have access to and purchase electric vehicles. Electric vehicles are structurally composed of motors, Electronic controls, batteries and other components to form the vehicle’s power system. For electric vehicles, many In addition to paying attention to factors such as the cruising range of the vehicle when purchasing, people will also pay attention to the performance of the vehicle, such as its climbing performance, and what factors will affect the climbing ability of a pure electric vehicle?
As far as the climbing ability of electric vehicles is concerned, it still needs to start from the motor of the car. Nowadays, electric vehicles all use reducers (not gearboxes, but also have two-speed transmissions) just to take care of normal urban road conditions. Furthermore, the single motor used in the existing electric vehicle, on the whole, the rotational speed and torque generated are relatively small, so it will only be affected by the torque of the motor when climbing a hill.
Taking the BYD Qin Pro as an example, the maximum torque of the motor of the electric version of the car is about 180N.M, while the torque of the hybrid version of the car is 245N.M. From this set of data The difference between the two versions can be seen above. In addition, from the fuel car, the car uses a gearbox (which can be considered as a segmented constant power). There is a lot of power at low rpm, that is, a lot of torque.
Therefore, it is also one of the factors that affect the climbing ability of electric vehicles. In addition, it is the influence of the capacity density of the battery. In order to ensure the power required for the maximum battery life of the vehicle, the pure electric vehicle will set the output power of the vehicle when it is designed. It is set within a reasonable range, so that the power and torque required by the vehicle to go uphill can be met without losing the cruising range. Fuel vehicles have a strong sense of power.
In general, the impact of electric vehicles’ climbing ability is affected by motor, battery and environmental factors. Of course, for current electric vehicles, there is no problem in climbing. No matter what kind of machine is used to drive the car, you must buy enough. Basic usage of a car.
