It is not impossible for Pacific Automotive Network to use solar panels on the roof of new energy vehicles. It is theoretically possible to install them, because their impact on the environment is less than that of traditional cars. largely optimistic, but current technology is not yet mature. Currently, to install solar cells, how to achieve the energy conversion rate of solar cells. It is no longer a question of converting it into electricity, but of storing it after conversion.
Why aren't purely electric vehicles equipped with solar panels to facilitate self-charging?
It is not impossible for new energy vehicles to use solar panels, but this technology is still in a bottleneck period at this stage, and the conversion rate of solar cell energy will not make a big breakthrough in the short termt term. term.
According to current statistics, the laboratory energy conversion rate of single crystal silicon can reach 25%, that of polycrystalline silicon can reach 20%, and that of thin films can reach 10% to 15%. Module efficiency translated into full-scale production: monocrystalline 16%~18%, polycrystalline 15%~17%, thin film 6%~8% (domestic).
Such an energy conversion rate is pitifully low for a purely electric new energy vehicle and cannot at all meet the charging needs of PHEV plug-in hybrid vehicles or household electricity charging is the most direct solution. The method involves ensuring that the sun is illuminated at the maximum angle. If there is no sun on a cloudy day, there will be virtually no energy conversion.
Some time ago, Toyota applied for protection of solar cell technology from the OffAmerican trademark and patent ice. This technology will initially be applied to the Prius, one of Toyota's first hybrid vehicles (HEV hybrids). The United States received a strong market response. This time, Toyota installed a solar battery system on the roof of the Prius to simply charge the auxiliary battery.
This system will be integrated into the Internet of Vehicles system. Through the current advanced weather forecasting system, this system will give priority to navigating the vehicle on the ground with the highest altitude angle of the sun, or park the vehicle on the ground with the highest altitude angle pupil. Where the sun is, this can get the best energy conversion. The Prius's chief engineer predicts that this can increase the range by about 10 kilometers per day.
