14 electric car battery maintenance, check and adjust front and rear brake. Check and adjust front and rear brake Front electric bicycles. The front brake by the right brake control, brake handle from the left rear brake control. When the front and rear brake adjustments to the left and right brake handle that can reach 50 percent of travel is a suitable and reliable brakes, brake shoes for excessive wear, should be replaced. 15, electric bikes should be checked before the chain lubrication. Feel and observe the links of the chain axis rotation is flexible electric car price, link corrosion is serious. If corrosion or rotation is not flexible, the right amount of lubricant should bear serious chain should be replaced. 16, the front electric bicycle riding, should check the tire pressure, steering handlebars flexibility, front and rear wheel rotation flexibility, circuits, battery power, electrical work conditions and lighting, speakers. Electric tricycle battery maintenance 1. Battery not lose power storage, power loss 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 capacity will decline. Under state power loss longer idle time, the more serious battery damage. When idle battery, charge it 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 in more than a dozen kilometers in a short time, it is likely that there is at least one battery set off a battery cell, plate softening, plate active material shedding short circuit. At this point, we should go to a professional battery repair mechanism to check, 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 with a battery-powered electric vehicles invention, and are not included in the scope of international recognition. Then there have been the lead-acid, nickel-cadmium, nickel-metal hydride batteries, lithium ion batteries, fuel cells as the power of the electric car. Electric tricycle electric tricycle cargo classification, this car is also divided into two kinds, one for the motor type, configuration and style and almost three-wheeled motorcycle, motor with large shaft center, with more than 500W motor, the amount of general cargo 300-600KG, equipped with inverted-switch three electric cars, and speed control system. The fastest road about 35 kilometers per hour. One for motorized three-wheeled, multi modifications made by the motorized three-wheeled, rear axle electric car trunk full use of motorized tricycle configuration Fuxing Bailong, trucks are more than a ton, can speed gearbox, configuration 4-5 Block 12 0AH large capacity battery, more than 900W DC motor, there is no cab and cab can also be equipped with hydraulic lifting devices, loading and unloading of bulk materials and plant used for garbage removal and other cities.
