1Use of energy by moving object

If solar charging panel power is supplied to high-voltage battery, then high-voltage battery charging efficiency is improved, but auxiliary battery may become discharged

Engineering Contradiction:
Improvehigh-voltage battery charging efficiencyVSAvoidauxiliary battery charge state
Core Design Contradiction:

Solution Approach 1:

The controller continuously monitors the charge states of both high-voltage battery and auxiliary battery, using feedback signals to dynamically adjust power distribution. When auxiliary battery charge state falls below a threshold, the controller automatically redirects solar power to charge the auxiliary battery, ensuring system reliability while optimizing high-voltage battery charging.

AI summary

A vehicle for supplying solar charging panel generated power to a high-voltage battery or an auxiliary battery based on a SOC is provided. The vehicle includes a motor, an electric field load, a high-voltage battery that supplies power to the motor, and an auxiliary battery that supplies the power to the electric field load. A battery sensor measures a SOC of each battery. A solar charging panel measures an amount of solar light and generates the power based on solar energy. A controller calculates generable power through the solar charging panel based on the measured amount of light when starting of the vehicle is off. The solar charging panel is operated to generate power when the generable power is greater than the power consumption in the power generation through the solar charging panel, and supplies the generated power to one of the batteries based on the SOC of each.
