Electric car, AC and DC electric cars electric vehicles. Generally speaking, the electric car is the battery as a power source for household electric tricycle, through the controller, motor and other components of electric tricycle Linyi, converts electrical energy into mechanical energy movement to control the current size of the change in speed of the vehicle. The first electric car manufactured in 1834, which is driven by a DC motor. Today, the electric car has undergone tremendous changes, type also varied. Electric car battery problem to cure repair summary: 1, make up water. Water shortage, all out of the question. And solubility related. 2, temperature. High temperature effect is good. And activity. 3, high voltage low current. Generally speaking, higher than the battery voltage is doubled. Current 0.01C. But not absolute. Only cure for severe 0V battery electric passenger tricycle, a much higher starting voltage electric tricycle, electric current is smaller. 4, the pulse frequency. This is not essential. 1945 in favor of the argument, saying that the crystal resonator is purely for granted, there is no experimental basis. Suggest that you use 200Hz, 1000Hz, 8330Hz experiment a bit. Electric tricycle price | White Dragon Machinery (certified) | electric tricycle provided by White Dragon Machinery Co., Ltd. Shandong.
