The next generation of electric vehicles may have a much higher capacity factor than conventional cars, according to a new report.
The National Renewable Energy Laboratory’s (NREL) “Capacity Plus” report, released Tuesday, found that “new, higher-capacity, hybrid vehicles with higher capacity, range, and energy density could be economically viable for fleets with higher energy needs than existing fleet vehicles.”
Capacity plus, or C+ for short, is a measure of how much a vehicle can hold on to compared to its expected use.
This means the capacity factor of an electric vehicle depends on how much energy it can consume in one charge.
The study found that in the case of the Tesla Model S, the capacity-plus rating for a Model S with a 90 kWh battery was 9.3.
That means that the vehicle can operate at the same maximum rated range as a normal car, but can hold about 70 percent more charge in one second than a car that has a 90-kWh battery.
In the study, the authors said that “the most important factor in the success of the next generation electric vehicle (EV) is its capacity.”
“If a Model 3 battery is able to handle 80 percent more energy than the maximum rated capacity of the car, then it could provide up to 90 percent more range than a Model X with a 70-kwh battery,” the report reads.
The report also found that electric vehicles with a larger battery could offer higher-speed charging. “
If the vehicle has a 100-percent battery, the vehicle’s energy consumption could increase by a factor of about 10,” the authors wrote.
The report also found that electric vehicles with a larger battery could offer higher-speed charging.
In fact, the report found that an EV with a 130 kWh battery could charge in 10 minutes while a 100 kWh battery takes 30 minutes.
The authors wrote that “high-capacity EVs can also increase their range, but at the expense of increased fuel consumption and emissions, and thus may not be economically feasible in a range-constrained world.”
The report said that it’s important to be aware of how “capacity-plus” vehicles perform on the highway and that the report did not address the issue of whether or not the vehicles should be equipped to charge at home.
“For these reasons, the National Renewables Laboratory does not recommend that the National Highway Traffic Safety Administration (NHTSA) adopt a standard for the certification of high-capacity electric vehicles,” the researchers wrote.
“It is important to note that the performance and safety profile of electric vehicle fleets may differ depending on the type of battery and vehicle design,” the NREL researchers concluded.
“While we believe that the adoption of a standard to quantify and quantify capability may be beneficial, we believe the assessment of the reliability and safety of these vehicles and the vehicle range can be done independently from certification.
The report was conducted by the National Center for Transportation and Infrastructure Policy at the University of Maryland, the University at Buffalo, the New School, the Center for Energy Efficiency and Renewable Transportation, the Energy Information Administration, and the National Science Foundation.
