Electric tricycle 4, to prevent exposure to high temperature conditions may cause the battery to increase the internal pressure of the battery is automatically turned on the pressure limiting valve forced sale of three-wheeled electric vehicles, a direct consequence of increased water loss of the battery, and the battery will inevitably lead to excessive water loss battery decreased activity, accelerated plate soften, charging case of fever, from the drum shell, deformation and other fatal injuries. 5, to avoid heating the charger output plug loose plug charging, the contact surface oxidation, and other phenomena can cause charging plug fever, fever too long will lead to a short circuit charging plug directly damage the charger, lead to unnecessary losses. When it found out that the case should be promptly removed oxide or replace the connector. 6, in the course of regular inspections wheeled electric, if the electric car to continue the mileage sudden drop ten kilometers in a short time, it is likely that the battery pack at least one battery has broken grid, plate softening, very plate active material shedding short circuit. At this point, it is timely to specialized cell repair mechanism to check, repair, or with a group. This can extend the life of the battery pack relative to maximize savings. Electric passenger tricycle electric passenger tricycle high-tech composite materials to build the body, its features are, corrosion resistance, impact low-cost three-wheeled electric vehicles, light weight, long life and other advantages. Widely used in the aviation industry, shipbuilding industry, environmental protection industry. Electric passenger tricycle custom steel frame link thickened three electric vehicles, combined with superior damping plate, perfect welding. Electric tricycle front passenger automobile glass using laminated glass, which has an excellent characteristic seismic invasiveness, which can be described as a very high degree of safety precautions. Glass with a 360 ° electric wiper, rain and snow to ensure the safety of riding. The latest three-wheeled electric vehicles, three-wheeled electric, White Dragon, White Dragon machinery provided by Shandong Machinery Limited. White Dragon Shandong Machinery Co., Ltd.
