A single-speed electric vehicle controller for children

Abstract

The invention relates to a novel single-speed electric vehicle controller for children. The novel single-speed electric vehicle controller comprises a field-effect tube driving module, a power interface module, a motor interface module, a control button module, a charging brake interface module and a field-effect tube module. The output end of the field-effect tube driving module is connected with the field-effect tube module, the field-effect tube module is connected with the motor interface module through a protective relay module, the voltage feedback end of the field-effect tube driving module is connected with the control button module, the power end of the field-effect tube driving module is connected with the power interface module, and the voltage feedback end of the field-effect tube driving module is further connected with the charging brake interface module through a charging brake control rotation stop module. According to the novel single-speed electric vehicle controller, the modules are organically integrated, the multiple functions such as motor current limiting, power undervoltage control, temperature compensation, undervoltage control and galloping protection are achieved, the control process of an electric vehicle is safe, safe riding is guaranteed, and the service life is prolonged.

Description

technical field [0001] The invention belongs to the technical field of electric vehicle control, in particular to a single-speed electric vehicle controller for children. Background technique [0002] The electric vehicle uses the electric power stored in the battery as the energy, and the motor drives the wheels to rotate to complete the driving of the vehicle. In the electric vehicle for adults, the controller is more complicated, and the CPU must be used to complete the data detection and control signal. output. For children's electric vehicles, they are small in size and have a single function. Only a common controller is needed to realize the functions of acceleration, deceleration, and braking of children's electric vehicles. In this type of electric vehicles, there are also Some vehicles that do not need acceleration and deceleration functions, that is, vehicles that use a single-speed controller, when in use, close the control button to make the relay close, then th...

AI Technical Summary

Problems solved by technology

[0003] The above control method has the following problems in use: 1. There will be electric sparks at the contacts of the relay when it operates, which will cause the contacts of the relay to stick together and make it impossible to stop, causing safety hazards for riders

2. This control method cannot realize the current limiting control of the motor, which will reduce the service life of the battery, controller and motor
