To charge the  electric delivery tricycle  ground with ground, basically riding the day after would charge, but we need to note that if your battery can travel 30 kilometers, while driving a 5 km or 10 km after charging it, but on the battery negative, even detract from life. This is because when the battery is fully charged, there will be some of the gas spill, this gas is produced by the decomposition of water electrolyte, the situation is a result of water loss occurs, if frequent charging this way, it is bound will increase the number of battery loss, causing the battery to quickly enter the expiration date. Therefore, the correct way is if the next day after the electric car is not used, it is best to give it a full charge, and in driving the 5 km or 10 km, power is sufficient to maintain the second day of the journey, it is best to wait until the next day use before charging, it will also reduce water loss batteries to extend battery life.
