I have seen many debates about how little electric vehicles have improved since their inception.

Those which believe electric vehicles haven’t improved much cite the fact that some old electric cars from more than 10 years ago achieved the same range as today’s. Their opposition stated that electric vehicles are improving, and that they are the best alternative to gasoline-powered cars.

I decided to investigate and find the truth. That is what let to the creation of this website in the first place. I started researching and analysing debates, and found flaws fairly often, so I needed an outlet to post my corrections to these repetitive issues to enlighten people so they could finally move on, so that is how this website came to be.

The GM EV1 is commonly used in these discussions. Its range was stated to be 70 to 100 miles, while today’s Nissan Leaf achieves 73 miles per charge, and its range is now on the lower end of the electric vehicle market. Even the much larger 2013 RAV4 crossover SUV achieves 100 miles.

The Tesla Model S, which is a luxury sports car that seats seven can achieve over 260 miles of range per charge, that is a significant improvement over the EV1, which, in its day was a technological milestone.

100 miles was a milestone in the 90s, and now a car would have to exceed 300 miles, so, the range of electric vehicles improves significantly. Prototype battery technology can provide up to 1,000 miles of range per charge, and range options keep increasing.

It isn’t fair to compare the EV1 to the Nissan Leaf because the Nissan Leaf is a modern, 4-door, 4 seat car with modern features. The EV1 was a very basic, tiny, subcompact car with only two seats, and it was built with a plastic body.

Even its shape was unusually aerodynamic.

As for performance, the Tesla Roadster accelerates from 0 to 60 MPH in 3.9 seconds, which most cars (whether gasoline or electric) cannot do, so that is another major improvement for electric vehicles. They were very slow 100 years ago.

Charge time for the EV1 was 8 hours using a 220 volt power outlet. Today, that is how long it takes using a 120 volt outlet, and vehicles like the Chevy Spark can charge to 80% of their capacity in 20 minutes.

My conclusion is that electric vehicles have improved significantly since their inception. Much of this is attributable to battery technology improvements.

The EV 1 was manufactured between 1996 and 1999, and the Nissan Leaf 2011 to present.

 

Purchasers of the Fiat 500e, which is the electric version of the Fiat 500 vehicle will be allowed to rent gasoline-fueled cars to ease concerns about “range anxiety”.

The rental service will be provided through the Enterprise car rental company for the 12 days per year, for the first three years of ownership. This rental incentive is part of the ePass program.

The Fiat 500e electric car can travel 87 miles per charge, which is far longer than most peoples’ daily commutes. However, people that want to make unusually long trips may use gasoline-fueled cars.

The Fiat 500e is to arrive at California dealerships this summer.

Is this enough to outdo Nissan’s Leaf and Chevy’s Volt? Maybe the Leaf, but not the Volt, which has a backup generator that enables it to travel as far as the owners want to, as long as they refill it with gas.

Smart City San Diego, with the mayor, unveiled their solar-powered electric vehicle project at Balboa Park.

In this case, solar panels directly charge the vehicles, rather than the traditional net metering approach, which involves charging the vehicles with power from the local utility company, and then offsetting that by supplying the electricity generated by the solar panels back to the electricity grid.

So these vehicles draw electricity from the solar panel, not the electricity grid.

The solar panels generate up to 90 kW of electricity, which can power up to 59 homes, assuming that the homes consume an average of 1.53 kW of electricity hourly (this fluctuates, but this is what all those spikes and dips averages out to).

This could power up to 72 typical American homes which consume an average of 1.25 kW hourly, and use 900 kWh of electricity monthly.

A 27 year old, Brandon Nozaki Miller, from Kanuma-shi, Tochigi, Japan (he now lives in Thousand Oaks, California) broke the land speed record for unfaired lightweight electric motorcycles. He achieved this using the 2012 Zero S ZF6  motorcycle on the Bonneville Salt Flats at a speed of 101.652 mph over a one mile distance. This was done at the 2012 Bonneville Shootout.

The motorcycle is in the unfaired lightweight electric motorcycle class because it weighs less than 150 kg (330 pounds, one kg = 2.2022 pounds). His weighed 128 kg. At the Bonneville Salt Flats, Brandon was  actually trying to break Keven Clemens record in the same class. Kevin’s record was set at a speed of 78.4 mph 78.4 mph at the BUB Motorcycle Speed Trials

Brandon also secured the FIM record for the kilometer distance at 102.281 mph.

I’m sure that many are wondering what enabled Brandon to achieve this, whether it was a lighter chassis, a motor with an improved power density, improved battery power density (power-to-weight ratio), which is the amount of power each kg of batteries can produce.

While it is possible to improve performance considerably in all these ways, the largest strides I have seen electric vehicles make is due to improved battery technology. This matters so much because the weight of a vehicle’s batteries is usually a significant fraction of its weight.

For example: The Tesla Roadster battery accounts for more than 1/3 of the entire car’s weight, so this slows it down tremendously. Replacing the battery with one that has twice the energy density, but the same capacity would facilitate blistering speed and hundreds of miles in additional driving range per charge, because it would weigh 495 pounds (224 kg), rather than the 990 pounds (449 kg) that it does now.

These motorcycles do use a 5.3 kWh li-ion (lithium-ion) battery pack. The family of lithium-ion battery technologies is the most powerful in the world, and their performance specifications vary significantly, so the fact that the batteries are lithium-ion is not enough information.

Lithium-ion batteries on the market do achieve energy densities in excess of 95 Wh per kg, though (the highest I have seen for li-ion is a 1,000 Wh/kg prototype), and power densities over 400 W (not to be confused with Wh) per kg. Lead-acid batteries, which pale in comparison (used for UPS devices, DIY electric cars, as well as gasoline-powered car starters) have an energy density of 30-40 Wh/kg.

Motorcycle MSRP: $11,495 USD.

Motor Trend editors drove a Tesla Model S EV 211 miles from Los Angeles to Las Vegas without recharging the battery pack to see how far it can actually go.

They turned the air conditioning off for most of the trip, but they realized near the end of the journey that they had a fair bit of extra range left , so they turned it back on due to the scorching hot weather.
