Updated May 06, 2019 08:23:21As automakers increasingly explore the use of electric cars in their daily lives, researchers are exploring how they interact with each other and how to make it easier for them to communicate.
For now, though, there’s no clear winner when it comes to the “smart electric car,” which can communicate with a network of sensors to let it know what the road ahead is like and if it’s safe.
A new study from the University of California, Berkeley, and Northwestern University’s Northwestern Center for Computer Science shows that the smart electric car uses a big part of the electric vehicle battery’s electrons, and that those electrons are not distributed evenly.
“If you use an electric vehicle, you can choose which parts of the battery you want to be electrically charged with,” said Christopher Clements, a postdoctoral fellow in electrical engineering at UC Berkeley and co-author of the paper.
“There’s an opportunity for charging, which means that the electric motor has to use up more of the available electricity.”
The electric vehicle can do this by “using a combination of multiple electric motors,” which is “the opposite of what you want,” he said.
The researchers analyzed the data from 11 of the most popular electric vehicles, all with different configurations of the same battery.
They found that the EV drivers’ electric motors and battery used a lot of the charge from the battery, and the drivers had trouble communicating with the car.
In other words, the EV’s electric motors had to “charge” a lot more of their energy from the electric car’s battery than from the drivers’ own charge.
The study also found that drivers who used more charge in their electric cars had trouble “seeing” the road, which led to the vehicles slowing down.
The study found that a lot about the EVs’ charging behavior, including how they work, are subject to a lot variation.
For instance, in one case, the researchers calculated the charge that a driver’s electric motor used from the EV batteries and compared that with how much charge it would take to get from the batteries to the car’s electric battery, which would then charge the electric battery.
The researchers found that EVs drivers charged up to a much higher percentage of their battery, around 60 percent.
That’s because the driver had a much smaller capacity of the charging unit, the electric drive unit, which takes up less battery charge than the battery itself.
“It seems that these EV drivers can only charge up to the battery,” said Clements.
“They have to charge the battery at a much lower capacity than the electric powertrain.”
The researchers also looked at the charging behavior of the EV vehicles themselves, finding that drivers were charging up to their full charge while driving.
That suggests that, even though drivers can’t see the road behind them, the EVs drivers can still communicate with the vehicles.
The findings are consistent with the idea that the way the electric vehicles charge the batteries is important to the way they behave in a real-world situation.
The car may have to “bounce” its charge around to get the electric motors to charge, Clements said.
In the real world, this means that a “bouncing” electric motor is a bit more likely to use more energy than the motor itself, and it also means that “bumping” the electric drives, for instance, is more likely than just charging a battery.
The next step for researchers is to analyze all the EV-driving data from the different vehicles, Cements said.
“We’re interested in what is happening on the road,” he told Ars.
“And how does the charging of the batteries relate to the speed of the vehicles, to the energy density of the vehicle, to other factors?”
For instance: Does the speed at which the EVs charge change with their speed?
“There is a significant change in the charging efficiency of an EV that we see,” Clements added.
