<p>A power supply system (22) of a car inner rear-view mirror. The power supply system (22) comprises one or more lithium battery packs (221) and a solar power supply apparatus (222), and the solar power supply apparatus (222) comprises a solar cell panel (2221) and a switching circuit (2222). The power supply system (22) further comprises a power management unit (223). The power management unit (223) is used for controlling the lithium battery packs (221) to stop supplying power to a rear-view mirror electronic device when the solar power supply apparatus (222) generates electricity needed for normal operation of the rear-view mirror electronic device. A car inner rear-view mirror comprising the power supply system (22) is further disclosed. By means of the effective power management unit (223), reasonable and effective utilization of the solar power supply apparatus (222) and the lithium battery packs (221) is controlled, and the service time and charging and discharging time of the lithium batteries are reduced, thereby helping extend the service life of the lithium battery packs (221).</p> |
