Title:
ELECTRIC QUANTITY MONITORING DEVICE, NAVIGATION SYSTEM, AND VEHICLE
Document Type and Number:
WIPO Patent Application WO/2017/075995
Kind Code:
A1
Abstract:
An electric quantity monitoring device comprises a switching circuit (11), a processor (12), a memory (13), and a communication circuit (14). When the switching circuit (11) reaches a timing cycle, the processor (12) is awakened, so that the processor (12) in the awakened state acquires a residual electric quantity of a vehicle-mounted power supply of the vehicle by means of a CAN bus. On one hand, if the residual electric quantity is less than an electric quantity threshold, the communication circuit (14) sends the residual electric quantity to a pre-stored mobile phone number; after the communication circuit (14) sends the residual electric quantity, the processor (12) returns back to a dormancy state. On the other hand, if the residual electric quantity is not less than the electric quantity threshold, the processor (12) returns back to the dormancy state; therefore, the electric quantity of a vehicle-mounted battery of an electric vehicle is monitored. The present invention also relates to a navigation system and a vehicle, each of which comprises the electric quantity monitoring device. Meanwhile, when the vehicle is in a stop state, the electric quantity monitoring device is periodically awakened to monitor the electric quantity, thereby reducing power consumption of the electric quantity monitoring device.
