Welcome to inquire! Contact: TOTAL. Electric car vehicle maintenance (5) electrical control complex structure, the user should not disassemble, repair. Such as local charging voltage instability, easy to make the charger fuse, we recommend using the AC voltage regulator. (6) when the bike feel heavier red backwards closed electric tricycle, and implementation of forward wheels have a slight friction within the sound are normal. (7) should not be overloaded riding, should not be placed too heavy items and bring people to avoid damage to the battery and motor. Electric tricycle battery maintenance 1. loss of electricity can not be stored in the battery, power loss means the battery charge state is not timely charge after use is likely to cause salinization of sulfuric acid, so that lead sulfate crystals attached to the plates in the battery, plug the electric ion The channel will cause charge does not go charging, the battery's capacity will decrease. Under state power loss longer idle time, the more serious battery damage. When the battery is idle, should be charged once a month, which can extend the battery life. 2 electric tricycle battery during use to conduct periodic inspection, if the electric bike to continue the mileage sudden drop ten kilometers in a short closed electric tricycle price, it is likely that the group has at least one battery cell off the grid, plate softening, plate active material shedding phenomena such as short circuit. At this point, should go to a professional agency to check battery repair, repair, or with a group. Electric tricycle history: the world's first electric tricycle car was born in 1881, French engineer Gustave human invention Te Lufu, which is a lead-acid battery-powered tricycle, and in 1873, by the British Robert Davidson invention with a battery-powered electric car electric tricycle factory closed, and not included in the scope of international recognition. Then appeared the lead-acid, nickel-cadmium, nickel-metal hydride batteries, lithium ion batteries, fuel cells as a power of the electric car.
