AI Technical Summary
Existing electric vehicle photovoltaic systems cannot perform dynamic energy dispatching under complex and variable lighting conditions, resulting in some photovoltaic modules failing to generate electricity and consuming system power when they are shaded. Furthermore, they lack active heat dissipation methods in high-temperature environments, leading to hot spot effects and battery safety hazards.
By monitoring the instantaneous current variance and cell surface temperature of the photovoltaic subarray in real time, the photovoltaic modules are dynamically isolated and shaded, and the remaining photovoltaic power is directly coupled to the cooling unit for heat dissipation, thus constructing a closed-loop control mechanism for all-weather dynamic anti-shake and absolute electrical anti-condensation.
It achieves millisecond-level hardware isolation of partially shaded photovoltaic modules, preventing backflow of electrical energy, providing active heat dissipation with zero battery energy consumption, and improving the adaptive scheduling capability of the vehicle's energy system and the safety of battery operation.
