One of the major questions for new potential EV buyers is, “How long does the battery last?” And it’s a natural concern. After all the battery is the most expensive single part on an EV.
Due to the fact that mass produced EVs are still a relatively new phenomenon, research on the long term life of a battery is not fully clear. However, research is beginning to come in – and the results so far have been surprisingly positive.
In this article from GreenCarReports, Nissan executives have discussed their efforts to repurpose old Leaf batteries. They commented that the batteries are outlasting the vehicles themselves! Read on:
Nevada continues to make headlines on the technology and renewable fronts. Now Las Vegas is home to one of the largest and most advanced charging stations on the planet. Take a read for the TechCrunch coverage below:
The Electric Drive Transportation Association has been tracking U.S. Sales of plug-in electric cars since 2010, when the first Nissan LEAF and Chevrolet Volt mass-market cars were introduced:
President Barack Obama during his 2011 State-of-the-Union address challenged the nation to put one million plug-in electric cars on U.S. roads during his term.
One Million EVs Sold!
It took a little longer, but the benchmark was achieved during October 2018, when 9,465 plug-in hybrid electric vehicles and 24,638 battery-electric vehicles were sold.
Total sales since 2010 were estimated at 1,015,980 at the end of October 2018.

Electrify America installed six dual-port DC Fast Charge systems from ABB at Premium Outlet Malls South on the corner of Warm Springs Road and South Las Vegas Blvd.
Electrify America, a non-profit organization funded by Volkswagen to install multiple DC Fast Charge stations on highways and roadways across America, has begun installing these systems in Nevada.
The Premium Outlet Malls South is a shopping district near Las Vegas Blvd and Warm Springs Road, just south of the Las Vegas Strip. The company is hosting six DC Fast Charge stations with 12 charging ports of various power-delivery capabilities for different model EVs equipped with different levels of fast-charge battery packs.
Two of the stations will carry “ultra fast” plug connectors capable of delivering electricity at a maximum power-transfer rate of 350 kilowatts. At this time, no plug-in electric car battery pack has been equipped to handle this combined amount of voltage and current flow from a DC Ultra Fast Charger. However, the installation of these systems will future-proof these DC Fast Charge systems near Las Vegas Blvd., so that newer vehicles with ultra-fast charging rates that will be developed over the next ten years, will still be able to use this site.
DC Fast Charge Station manufactured by ABB is one of six that has been intalled at Premium Outlet Malls South just south of The Las Vegas Strip.
The plug-in connectors on these charging stations are based on the SAE International standard for DC Fast Charging, known as the Combined Charging System, or CCS. The latest CCS version 2.0 coincidentally has a maximum power rating of 350 kilowatts, that can be achieved through a combination of voltage and current settings. Voltage can be adjusted from 200 – 1000 Volts DC, while current flow can reach a maximum of 500 Amps.
Three of the six stations at the Las Vegas Premium Outlet South shopping district will be also use a similar CCS connector, but have a maximum power-transfer capability of 150 kilowatts.
The last DC Fast Charge station has two different connectors. One is a CCS-compatible plug rated at 150 kilowatts while the second plug is a CHAdeMo standard plug rated at 50 kilowatts. CHAdeMo is an older DC Fast Charge standard developed by the Tokyo Electric Power Company (TEPCO) and implemented more than a decade ago. It has been used by Japanese automotive manufacturers in the Nissan LEAF and Mitsubishi i-MiEV that were sold in the US during 2012 and beyond.
Each CHAdeMo-equipped vehicle had two separate charging ports, one for the standard SAE J1772 Level 1 and 2 AC charging systems, as well as a separate CHAdeMo port for DC Fast Charge systems.
All six DC Fast Charge stations have been provided by ABB, a worldwide manufacturer of electric vehicle supply equipment for the automotive industry.
Currently, the Tesla Supercharger network of DC Fast Charge stations are rated at 120 kilowatts to enable Tesla Models S, X and 3 to travel cross-country and recharge a 250-mile range pack in about forty minutes. Tesla owners can purchase an optional CHAdeMo adapter cable but at 50 kilowatts, charging time is closer to two hours to top off a Tesla model battery pack.
A 150-kilowatt DC Fast Charger should reduce the time required to refill an electric car’s battery cells to about 35 minutes, while a 350-kilowatt Ultra Fast DC Charger should be able to recharge a compatible battery pack in about ten minutes.
Implementing this EV technology roadmap to enable an electric car future may have some speed bumps over the next ten years.
Building out the necessary charging station infrastructure to safely deliver electricity at the same rates as high-voltage transmission lines will still be a tremendous challenge to designers, installers, product managers, maintenance people and even first responders to a traffic accident or DC Fast Charge station malfunction.
A lot of “real world” testing will be required with each new level of DC Fast
Charge technologies over the next decade.
Already, Electrify America has experienced a recall of 350-kilowatt DC Fast Charge cables after recent testing found a problem in some of the units. Retrofits to the original cable designs were required to systems that have already been installed.
An onboard card reader can process all major credit cards for the purchase of electric power, as well as process payments through Apple Pay and Android Pay.
DC Solar has installed 19 portable trailers around the Las Vegas valley that are equipped with ChargePoint AC Level 2 charging stations to provide electricity at no cost to electric car owners.
The electric power for the ChargePoint station on each trailer can be generated by three portable resources: adjustable photovoltaic solar panels, a battery backup storage system, and a biodiesel generator.
Each DC Solar charging station trailer also has digital LED display screens on both the ChargePoint station control panel and alongside the full length of the trailer that can be leased to businesses to provide advertising announcements. Advertising revenue can be used to offset any maintenance or biodiesel costs incurred by DC Solar while providing free electrons to electric car drivers.
DC Solar portable ChargePoint stations installed in the Las Vegas valley are located at:
1. 5965 W. Sahara Avenue
2. 4030 W. Charleston Avenue
3. 1555 E. Flamingo Road
4. 2151 N. Rancho Drive

Locations of more than 300 ChargePoint stations in the Las Vegas valley and throughout the rest of Nevada can also be found through a map app provided by ChargePoint at this link:
The Nevada Electric Vehicle Accelerator (NEVA) website also includes the Plugshare.com mapping service, that can be used to locate both ChargePoint and non-ChargePoint EVSE charging station sites throughout the state and around the country:
Update: During March 2018, DC Solar removed its trailers from all locations due to a billboard permitting requirement requested by the City of Las Vegas. The company will re-install its trailers at the original sites once the permitting requirement has been resolved.

Magelec Propulsion MGU 61R electric motor with F6R Gearbox is used by NextEV racing team for the Formula E international circuit.
The NextEV racing team uses this motor in its Formula E car. Maximum speed is 225 km/hour up to 12,000 rpm and acceleration time from 0-100 km/hour is 3.0 seconds.
Vehicle electrification is becoming accepted by SEMA attendees and its hot rod car culture. During a Vehicle Electronics Forum led by John Waraniak of SEMA, discussion panel members agreed that some form of vehicle electrification will be required to achieve CAFE standards of 54.5 miles per gallon by 2025.
EVs were also the best platforms to enable autonomous, self-driving vehicles.
Waraniak began his automotive career with Hughes Aircraft and GM by working on the pioneering Sunraycer, a solar-powered electric car that won the very first World Solar Challenge race in Australia during 1987. The SunRaycer technology was also implemented into the GM Impact prototype, the predecessor to the EV1 electric car program launched by GM during the 1990s.
