Proper use and maintenance of electric vehicles at the time of the lithium battery is charged, should be charged in accordance with the scientific method of charging, can not in accordance with the subjective experience of operating errors. Try to charge the battery to 40 percent in a cool place. This allows the battery protection circuit to operate in their long shelf life. If the battery is fully charged will be placed at high temperatures, the battery will cause great damage. Due to excessive low discharge will be scrapped in order to avoid such situations occur four passenger electric tricycle, do not store a fully discharged battery. Should be stored until some electric charge, and fully charged before use. The main impetus comes from the electric tricycle electric tricycle battery electric passenger tricycle price, most lead-acid batteries for electric tricycle battery electric passenger tricycle with canopy, so the battery life affects driving distance electric tricycle, battery maintenance is available from the following six aspects. 1, the right to discharge the battery charging time to grasp the depth of one charge best when 60% -70% 2, loss of electrical power loss at non-state that are not stored in a timely manner after charging the battery. Loss of power in the state of storing the battery, it is prone to sulfate, lead sulfate crystals attached to the plates, plug the electric ion channels, resulting in insufficient charging, the battery capacity decreases. Loss of power idle state longer, more severe damage to the battery. Therefore, when the battery is idle, you should charge it once a month, so that the battery can better maintain a healthy state. 3, to avoid large current discharge electric car start, manned, uphill, use pedal power to avoid momentary high current discharge. Likely to lead to large-current discharge lead sulfate crystals, to the detriment of the physical properties of the battery plates.
