Electric vehicles, AC and DC electric cars electric vehicles. Generally speaking, the electric car is the battery as an energy source, through the controller, motor and other components, the 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. Why electric vehicle battery life premature cause of your premature short-lived electric car battery produce small series of finishing a few points below the electric car quotes, everyone is willing to help the battery premature cognitive reasons:? 1, the owners have no awareness of battery maintenance causing serious damage to the battery sulfide. Must wait until the battery could run over repair and maintenance, then the repair more difficult. In fact, six months maintenance time, the natural extension of the life of a lot, but the owners do not have this awareness. Battery damage, mostly caused by excessive loss of water from the beginning charger. 2, big battery factory technological innovation, causing consumers to recognize famous lose fooled. What is technological innovation? Will reduce raw material point out a few of the more than Lianying Chang electric car prices, products are still ISO9001 certification, still one year warranty. Battery industry chain happy, or the expense of consumers. 3, charger killer. Points inferior charger electric car charger and aging ranks, these batteries are generally in the battery killer after eight months to play out the role of the killer. The reason, in line with these new batteries battery killer taste, as the battery ages, the battery can not meet the requirements of the electric car killer, to the year in June, the rapid water loss scrapped battery deformation. 4, luxury electric cars starting current, causing the battery vulcanization. If the owners start the car, slow acceleration, battery life and mileage natural increase 20%.
