Welcome to inquire! Contact: TOTAL. 1920-1990 Stage: With the development of the internal combustion engine technology and Texas oil increases, the electric car in 1920 after gradually lost its edge. Car market gradually to replace the internal combustion engine driving a motor vehicle. Only in a few cities retain very little and very limited tram and trolley car battery (with lead acid batteries, used in golf courses, forklifts and other fields). Development of electric vehicles since half a century of stagnation. With billowing oil resources to the market, people almost forget that there exists an electric car.

Select models feature electric vehicles in actual use, fully enclosed passenger tricycle, fully charged can travel many kilometers in the end? This is related to many factors passenger tricycle wholesale prices, and manufacturers are the main factors related to the efficiency characteristics of the motor, battery capacity and life characteristics of passenger tricycle pictures, and other factors related to the objective situation: the rider's weight, often riding road conditions, the need for frequent use of the brakes, how the rider's riding habits and so on. Need to remind consumers to pay attention to another problem: the battery capacity will grow with time gradually smaller, fully charged can travel the distance will be reduced, when the maximum travel distance of the old battery can not meet the day's traffic When needed, it can be considered maintenance or replacement battery sent a new battery.
