Best Steam Cleaners : Popular science knowledge: Mobile door-to-door car washing machines generally use 48V batteries for power supply. The machine and tricycle share a set of batteries. Purchase a tricycle custom car and carport and add a group of 48V32A batteries. Approximately calculate the full capacity of the 800-watt battery of the tricycle. Electric vehicle motor power is related, for example, the motor power is 800 with 48V32AH battery, the speed is 35km per hour, and the theoretical mileage is about 63km. When the load increases, the output torque of the motor increases, and the power increases. At this time, the mileage is reduced. It is also related to driving road conditions and ambient temperature. When the road conditions often climb or start, the mileage will be shortened. Because the current during climbing and starting is larger than the average current, the time will be shortened. Changes in ambient temperature also affect battery capacity. T...
