A system and method for automatically limiting power consumption of an electric vehicle

Abstract

The invention discloses a system of automatic electricity consumption limiting of an electrical vehicle. According to the technical scheme, the system comprises a first stepping motor which is arranged on a base board of a cab and can slide along the base board through a sliding device, an output shaft of the first stepping motor is provided with a connector, and a connecting groove used for jointing the connector is formed in a rotating shaft of an accelerator pedal. When the surplus electricity value of a battery is smaller than a threshold value, a controlling device controls the sliding device to drive the first stepping motor to slide so that the connecting head can be jointed with the connecting groove; when the pressure value is smaller than a first preset value, the controlling device controls the first stepping motor to reversely rotate and rebound the accelerator pedal; when the pressure value is bigger than the first preset value but smaller than a second preset value, the controlling device controls the first stepping motor to stabilize the accelerator pedal; and when the pressure value is bigger than the second preset value, the controlling device controls the first stepping motor to rotate forwards and drive the accelerator pedal at a constant speed.

Description

technical field [0001] The invention relates to a system and method for automatically limiting power consumption of an electric vehicle. Background technique [0002] Nowadays, cars are a life necessity that is necessary for ordinary life. Cars provide people with easy and fast mobility, thus gaining popularity and occupying an important position in our lives. [0003] However, the increase of existing internal combustion engine vehicles has become a cause of serious environmental pollution due to the increase in the exhaust gas emitted by the vehicles. In order to solve the above-mentioned air and environmental pollution problems, we are actively conducting research on electric vehicles (Electric Vehicles, EVs) that use electric energy as a clean fuel, and launching products that apply these technologies. [0004] In particular, with the strengthening of environmental regulation and the trend of energy conservation around the world, the demand for environmentally friendly...

Problems solved by technology

[0005] During the use of electric vehicles, increasing the battery capacity of the electric vehicle will lead to an increase in the weight of the vehicle body. Therefore, the distance that the electric vehicle can travel through a full charge will be limited; The car is far away from the special charging station. At this time, if the driver continues to drive badly, such as stepping on the accelerator vigorously and deeply at the traffic light, the battery will output a large current in an instant, and the remaining battery power will drop sharply. The cruising range of the electric vehicle is reduced, and it is unable to continue driving when it stops halfway without electricity, causing great trouble to the driver.
