The disclosure describes embodiments of an electric quantity monitoring device and vehicle. In some embodiments, the electric quantity monitoring device comprises a switching circuit, processor, memory, and communication circuit, wherein the switching circuit awakens the processor when arriving at a cycle, and then the processor in the awakened state acquires the remaining electric quantity of a vehicle-mounted power supply of a vehicle through a CAN bus; on the one hand, if the remaining electric quantity is lower than a threshold electric quantity, the communication circuit sends the remaining electric quantity to a pre-stored mobile phone number, and the processor restores a dormant state after the communication circuit sends the remaining electric quantity; on the other hand, if the remaining electric quantity is not lower than the threshold electric quantity, the processor restores the dormant state, thus achieving monitoring of the electric quantity of the vehicle-mounted battery of the electric vehicle.
