Provisions of sightseeing bus Traffic Law on Tourism

In addition, due to the limited storage capacity of the battery, it consumes too much energy too quickly, and once it is charged, it will greatly reduce the driving range. For example, an electric sightseeing bus using 36v and 12Ah lead-acid batteries can travel from 120 to 140km on one charge when the vehicle speed u is equal to 30 km/h, and the driving range after one charge will be less than 100km when the vehicle speed u is 40km/h.. Therefore, regardless of safety or technology, the speed of electric sightseeing bus should strictly follow the relevant national standards and should not unilaterally pursue high speed.

The battery pack of the electric sightseeing bus is generally composed of three or three single cells connected in series. If the terminal voltage of each battery is different, the battery with large terminal voltage will be overcharged first. At this time, because the voltage value of the battery pack does not reach the constant voltage state, the first battery will be damaged due to overcharge. The damaged battery will cause other batteries to be damaged due to overcharge because of low voltage.

Therefore, the voltage error of each battery in the battery pack should be controlled within 0.03 V, and the internal resistance voltage and discharge time of the battery are the same or similar, which is also a prerequisite for maintaining the effective driving range.
