Electric car does not need recharging

The Aptera Electric Car model can travel more than 70 km / day with sunny conditions. The car uses solar power.

Recently, Aptera (USA) has launched a 3-wheel electric vehicle with the same name with a bold promise: “Users will never have to plug in their car with solar panels and design. slippery aerodynamics ”.

A big plus

A big plus point of Aptera car is “never” have to plug in the charger. This electric vehicle is designed with the use of solar energy and it has more than 180 panels installed into the general structure of the vehicle. Every hour of parking in the sun will help the car recharge about half a kWh into the battery. Aptera said, this car lost about 3 kWh of electricity to travel a distance of 48 km.

The feature is standard, Aptera says, and it hopes to start shipping the car to customers by the end of next year (currently pricing has not been announced). Of course, the Aptera can still be charged like a standard electric car, and the version with the largest battery can go more than 1,600 km between charges.

The sun has always been a part of Aptera’s design. Back in 2007, the Aptera prototype had enough solar panels on the roof to run the ventilation system, keeping the car cool when parked in the sun.

Thanks to worthwhile improvements over a decade to solar technology, the sun is able to power heating, ventilation and air conditioning systems more. Toyota has launched a similar cooling system, the Solar Panel Roof, in their popular hybrid car, the Toyota Prius.

Aptera’s CEO Chris Anthony has talked about the technology behind electric cars that never need to be plugged in and about how important this is. Building a car that “never needs charging,” says Anthony, is definitely not easy.

“We wanted to launch this system as part of our story, but it took a while to develop and fully test it in real-world conditions. The hardest part about solar energy in a car is that you don’t put up a flat battery at an exact angle to the sun all the time. Basically, we have 5 curved solar panels that will never be perfectly aligned to collect solar energy.

Therefore, it is difficult to model correctly for our initial analysis. However, the National Renewable Energy Laboratory has an excellent open data set on the solar energy generated from a single location anywhere in the world. This gives a good start and helps us to complete the system design.

We then build our actual solar pack for the car and put all the panels in the right angle and position for the actual test to go in the shade and at dusk.

With over 1,000 hours of real-world testing, Apterah now has solid data that blends in with the original model. All of this adds up to a rechargeable system that gives the Aptera around 4.4 kwh per day in the summer sunshine in San Diego and it will cover more than 70 kilometers.

To do this, the car has applied new technological advances. The biggest advancement is in panels that can be bent to the car’s unique curving shape. In the past, panels were too brittle to break easily when bent. The company tried early solar panels that were more flexible but produced less energy.

Through working with solar cell manufacturers, the company was able to access panels that were flexible enough for demand and still produce electricity at 24% efficiency. This has allowed the company to make this “no-charge” system possible for the driving demands of most drivers today

Predicting the number of people who will actually use the Aptera product as a car that never has to be charged and who will plug it in regularly, Anthony said, the statistics show that the majority of drivers all vehicles go less than 48 km.

So the company hopes most people can make the system work according to their lifestyle. Any power generated from outside the vehicle will have transmission and conversion losses associated with putting that power in your battery box. But solar power for the Aptera will go straight into the battery box. This direct system is by far the most eco-friendly in terms of fueling a vehicle.

The system also saves people time along with providing free energy from the sun. However, the vehicle may need a spare plug for emergencies or special occasions. The company is creating remote inductive charging interfaces, says Anthony.
