What is the difference between non - zero start and zero start of electric vehicle?
[non zero start electric car] is in the static state is not started, but to have a certain speed can start. Non zero start to zero start, although there are many bad, such as batteries and motor is not good, but as long as the proper use, or no problem.
 is zero start the electric car when the ride started direct start, does not need external forces to make the wheels move up, then slowly start, there is now the electric car basically no nonzero start.
[non zero start to zero start]In fact, the non zero start is also very dangerous, have a go cart, pushed the car ran up, because the large front wheel has been set up, like a horse hoof like stand. Several control boxes were disassembled, and the first step was to cut off the speed limit line. After several times the disassembly was to change the zero start, and it was found that the circuit board was made of multilayer board and patch element.Besides, there is no schematic diagram, so there is no way to start, so it can only start from the outside, the principle of non zero start is to use a Holzer component to detect whether the wheel is moving and judging speed.Then, to decide whether the electricity, so you can simulate Holzer give a trigger signal to the CPU, it can realize zero starting without body, what time can recovery recovery.The principle is very simple, the control box leads to the three line to the wheel sensor, a line is +5V, a trigger line, a wire, trigger line usually have the potential of +5V or so, when the Holzer element induction to the magnetic field, the trigger is grounded, and after the restoration of +5V magnetic field.
