Toyota has ambitions over the concept and is to start testing an onboard solar recharging system where the hood, the roof, and back are covered with cells. The solar roof can charge while the car is on the move.
The World Solar Challenge is a continuance race crosswise over Australia for solar powered fueled vehicles, and every portion demonstrates to us what is conceivable when cars are built for most extreme productivity, Entrants are not really the sorts of cars you can load the family into and take off on a vacation, however, a portion of the advancements they utilize has been adjusted to cars of a progressively customary shape.
Bertel Schmitt, The Drive, said, “The solar roof could morph from mostly a marketing-device to a helpful feature.” He noted that, referring to plug-ins, “On a fair-weather day, the juice would be provided by the sun, a big improvement especially for people who don’t have their own garage.”
The ambitious and recently revealed Lightyear One EV is one, which is being developed by members of Solar Team Eindhoven who won the World Solar Challenges in 2013, 2015 and 2017. These guys reckon they can leverage five square meters (53.9 sq ft) of solar cells embedded in the roof and hood to power the car for up to 20,000 km (around 12,500 mi) of clean travel per year. Toyota has also been exploring the potential of solar-powered cars for a little while now, first introducing a solar roof option for the production version of its Prius in 2012. The latest production iteration of this developed together with Panasonic generates 180 W and adds around 6.1 km (3.8 mi) of battery-only range per day, when left to charge up in ideal conditions.
By examination, Toyota anticipates the most recent exhibit, which it has fitted to the rooftop, hood and back incubate of a demo model Prius, to create around 860 W. This jump comes politeness of new and improved solar powered cells created by Sharp with a transformation proficiency of 34 percent (contrasted with 22.5 percent of the generation form), and can apparently include 44.5 km (27.6 mi) of battery-just range every day.
Whereas the production model will only charge the battery while parked and otherwise just feeds power into the car’s onboard navigation systems and the like, the new demo version can charge the car while it is being driven, stretching that range out to 56.3 km (35 mi).
Toyota Press released states, the demo car employs a system that charges the driving battery while the vehicle is parked and also while it’s being driven.” This was seen as an interesting development expected to lead to improvements in the electric car’s cruising range and fuel efficiency.
“Previously, the Prius PHV charged the driving battery only while the vehicle was parked. However, with improvements in power generation output, the demo car employs a system that charges while the vehicle is being driven. This is expected to boost the BEV-mode cruising range and fuel efficiency significantly.
Toyota is set to start testing the new car this month on public roads in Japan, and will use the trials to gather data on the cruising range and fuel efficiency. It is collaborating with Sharp and Japan’s New Energy and Industrial Technology Development Organization on the venture, with an eye to developing more advanced onboard solar recharging capabilities for its vehicles.
