Failure inspection of electric bumper cars, industry news-SKP company

First, the vehicle does not take electronic reasons A control circuit failure 1. Power Control part circuit failure power control part is divided into 1, battery power plug 2, power master switch, 3, controller power input plug three parts * battery power plug is not plugged or not properly plugged, can not provide power for the driving of vehicles, all vehicles do not go. * The power of the battery is transferred to the middle of the controller with a main power switch. If the main power switch is not turned on or the main power switch is damaged, the battery cannot normally transmit power to the controller, so the vehicle does not leave. * The power input controller of the battery has a four-hole power input and output line group plug. The red and black groups are the battery power input lines, and the brown and black groups are the output lines of the controller to the motor, if the power plug is not plugged in or has poor contact, the vehicle will not leave. 2. The Circuit of the motor control part is faulty. The driving of the vehicle consists of three parts: 1. The output power supply of the controller, 2. The motor controls the switch control power supply and switches the direction of the power supply, 3. The driving power provides the driving force, if the power supply of the controller cannot reach the motor, the vehicle will not leave. * The controller power output plug is not plugged in or has poor contact, so the vehicle does not go. * The motor control switch is not pressed to the forward or backward position, so the vehicle does not go. * The motor control switch is damaged and the sound vehicle does not go. * There is a joint between the motor outside line and the control line. The joint is not connected or has poor contact, so the vehicle does not leave. B controller failure 3. The controller does not start the controller only outputs the power supply for the motor to run when it is started. The controller does not start, so the vehicle does not leave. 4. Controller failure whether the controller fails or not can generally be heard from *: after pressing the start switch, there is no start tone and no music playing; * Lighting: the standby indicator light and the start indicator light are not lit; * Power supply: measure whether there is voltage in the motor control switch or the motor power input plug. The controller failure cannot output power to the motor, so the vehicle does not go without C Power Failure 5. The battery power is insufficient. The normal working voltage of the motor is 12 V. When the voltage is lower than 11 V, the running speed of the motor will slow down and the output power will become smaller. When the voltage is lower than 7 V, the motor will be close to not working. The battery power is too low, so the vehicle does not go. 6. The battery is damaged. The battery voltage is very low. After long-term charging, it still cannot recover to the voltage above 12 V. It can be judged that the battery is damaged and the battery is damaged, so the vehicle does not leave.
