EMERGENCY LIGHTING DEVICE HAVING BATTERY LEVEL INDICATING FUNCTION

An emergency lighting device includes a rechargeable battery module, a charging control module, a processing module and an indicator module. The charging control module is connected to the rechargeable battery module, and has a first monitoring point and a second monitoring point. A first monitoring resistor is disposed between the first monitoring point and the positive electrode of the rechargeable battery module. The second monitoring resistor is disposed between the first and second monitoring points. The processing module is connected to the charging control module, and has a first monitoring pin and a second monitoring pin used to detect the first voltage of the first monitoring point and the second voltage of the second monitoring point respectively to perform a battery level calculating mode and obtain the estimated battery level. The processing module controls the indicator module to perform a light-emitting mode according to the estimated battery level.
