The smart battery app voltage display indicates: the output voltage of the battery, that is, the voltage supplied to the DC motor is how many volts, generally it is about 50v for a full charge. As you use, the power of the battery will decrease, and the output voltage will also decrease. When it reaches a certain limit, about 42v, the electric vehicle cannot be used normally. Therefore, the actual function of the smart battery app voltage display is to monitor the power level and indirectly let the user understand the battery life setting.

1. With the use of smart battery app voltage display, the power of the battery will decrease, and the output voltage will also decrease, as low as a certain limit, about 42v, the electric vehicle can not be used normally.
2. The actual function of the smart battery app voltage display is to monitor the power and indirectly let the user understand the battery life setting of the electric vehicle.
3. The smart battery app voltage display is the embodiment of the power display. The power is the on-voltage. Most electric car battery displays have 4 lights. The on and off of the 4 lights correspond to the corresponding voltage.
4. The full electric voltage of the tram is about 50V, and the charging point is usually about 48V for the smart battery app voltage display, because the voltage for a manned person is only 46V.
