The invention provides a vehicle
electronic equipment charging control method and
system, and relates to the technical field of vehicle
electronic equipment charging control. A charging
voltage threshold value is set according to rated
voltage of an
energy storage device, and a power supply output
voltage valley value is collected in real time and compared with the threshold value; and dynamically determining a charging control
mechanism based on a grading judgment rule and a
delay protection strategy according to a comparison result, and then circularly executing charging control. Dynamic on-off control of a charging circuit is realized through real-time monitoring and grading judgment of the valley value of the output voltage of the power supply,
delay protection is automatically triggered when the voltage of the power supply is lower than a threshold value, and invalid or dangerous charging is avoided during an unstable voltage period, so that
power supply voltage fluctuation can be adapted, damage to
electronic equipment caused by unstable power supply is reduced, and the service life of the electronic equipment is prolonged. The working reliability and the service life of the vehicle electronic equipment are improved. Meanwhile, closed-loop feedback is formed by circularly executing collection, comparison and
control logic, and the stability and reliability of the
system under complex working conditions are improved.
