AI Technical Summary
Existing vehicle battery charging strategies have problems such as excessively long timed wake-up times leading to power depletion risks or frequent charging increasing power consumption. Furthermore, they do not consider the impact of ambient temperature and battery life on capacity, resulting in battery life degradation.
The voltage monitoring module monitors the voltage during vehicle sleep mode, and combines the external ambient temperature and battery cycle life information to correct the compensation voltage threshold, thereby enabling graded judgment on whether charging is needed, and turning on or off charging when conditions are met, reducing static current consumption.
Accurately determine the need for power replenishment, reduce static current consumption, avoid power depletion and battery life degradation, and improve the accuracy and efficiency of power replenishment timing.
