Chevy Bolt EV: 70,000 Mile Battery Degradation

After 70,000 miles, I decided to review the data that I have gathered for nearly two years of driving the Bolt EV. Based on my estimates, my Bolt EV has lost a noticeable amount of battery capacity. To estimate the amount of degradation, I compared kWh used versus the battery percentage displayed at the station, and I was able to create a timeline of total estimated battery capacity.

EV Chargers, an informal discussion with James (“James and Kate”)

Informal discussion about chargers and charging needs for the future. Being significantly more experienced I was keen to pick Jame’s brain on a few things that have been on my mind.

Although, not staged for videoing and sharing the cameras were rolling and I thought many others might be interested in the discussion.

With thanks to James for his views and permission to share.

Good morning, good afternoon and good evening wherever you are in the world, welcome to EV News Daily for Tuesday 30th October 2018. It’s Martyn Lee here and I’ve been through EV story today so you don’t have to.


Thank you to for helping make this show, they’ve built the first marketplace specifically for Electric Vehicles. It’s a totally free marketplace that simplifies the buying and selling process, and help you learn about EVs along the way too.


And hello to two new Patreon supporters, as new Producers of the Podcast at $5 (the one posh coffee a month level) its ANDREW MURPHY and EV SOLID STATE aka MATTHEW WILLIAM HART.



A quick stat on the rise and fall, and fall and fall of Diesel from Matthias Schmidt @auto_schmidt: “European #diesel mix of new passenger car sales fell below one third in September… Sep YTD: 9% Last 4 qtrs: Q3 ’18: 35.2% Q2 ’18: 36.7% Q1 ’18: 38.5% Q4 ’17: 41.6% Last time annual diesel mix fell below 1/3 was the year 2000 (32.3%)”  


A new update today about Electrify America progress ahead of the on onslaught of EVs which should be coming 2019, at least early 2020. They have 30 fast charging stations now online and a huge task ahead of them to spend the $2bn settlement with the EPA and California Air Resources Board over dieselgate. Of those 30 stations, most have 7 CCS chargers plus a 1 CHAdeMo point. This weeks question of the week is where would you put a charger – if you were thinking Walmart, they’ve beaten you to it. Over 100 off the Electrify America chargers will be at a Walmart store. But that’s still a drop in the ocean with more than 2,000 Ultra Fast chargers in place by June 2019. “Electrify America DC fast charging stations display clear, up-front pricing. Electrify America charging will include the following elements: $1.00 session fee + per minute charging cost + idle fee of $0.40/minute (if applicable). Our introductory charging cost pricing is $0.30 to $0.35 per minute of charging”



“While battery-powered vehicles may be cheaper to run and maintain compared to their petrol- and diesel-powered cousins, the European Union isn’t yet the perfect place to charge them and keep them going because more than three quarters (76 percent) of the EU’s charging points are concentrated across just four countries – the Netherlands, Germany, France and the UK. What’s more, those countries only make up 27 percent of the Union’s total area” reports “The country with the most dense concentration of electric vehicle charging points in the EU is currently the Netherlands, where 28 percent of charging points cover one percent of the total area of the EU. The Netherlands also has solid fast charging networks like Fastned. There is currently around 100,000 charging points the in the European Union according to the European Automobile Manufacturers’ Association (ACEA), and that number should multiply at least 20 times by 2025 giving the EU 20 million charging points to handle the anticipated rise in sales of plug-in cars. To meet that target, 1.9 million charging points need to be produced and sold within 7 years.”



“The Chinese government has come up with a plan to accelerate infrastructure construction for electric vehicles (EVs). Chinese premier Li Keqiang at a state council meeting last week released a guidance plan for the EV industry, aimed at building sufficient charging poles to meet demand from at least 5mn EVs by 2020.” according to Argus Media: “The plan requires all parking spots at new residential buildings to have charging poles and at least 10pc of spots at public parking facilities to have charging poles. This is to ensure one charging pole in a public area for every 2,000 EVs. China is the world’s largest EV producer and consumer. It produced 795,000 EVs last year and is on target to produce 1mn EVs in 2018. Beijing is aiming to double production of EVs to 2mn by 2020 to save energy and curb pollution. China produced only 8,200 EVs in 2011. China as of August has installed at least 662,000 charging poles across the country — 275,000 public poles and 387,000 private poles. The central government’s guidance plan comes after many Chinese provinces introduced regional plans to boost the use of EVs.”

Researchers at the Department of Energy’s Oak Ridge National Laboratory have demonstrated a 120-kilowatt wireless charging system for vehicles–providing six times the power of previous ORNL technology and a big step toward charging times that rival the speed and convenience of a gas station fill-up. The wireless system transfers 120 kilowatts of power with 97 percent efficiency, which is comparable to conventional, wired high-power fast chargers. In the laboratory demonstration, power was transferred across a six-inch air gap between two magnetic coils and charged a battery pack. ORNL researchers created and demonstrated the world’s first 20-kilowatt wireless charging system, which is being modified for applications such as commercial delivery trucks. To achieve 120 kilowatts, the ORNL team created a new coil design co-optimized with the latest silicon carbide power electronic devices for a lightweight, compact system. The system’s architecture takes energy from the grid and converts it to high-frequency alternating current, which generates a magnetic field that transfers power across a large air gap. Once the energy is transferred to the secondary coil, it is converted back to direct current and stored in a vehicle’s batteries.



“We’ve seen spy photos of the next-generation Kia Soul a couple of times in the last few months and it’s only natural that a debut is imminent.” reports Anthony Karr from “Our friends from The Korean Cars Blog report the standard ICE-powered and fully-electric versions of the car will make their official premieres at the Los Angeles Auto Show in the second half of November this year. Nothing is confirmed at the moment, but it is believed sales in the United States will kick off in the second quarter of 2019. As far as the Soul EV is concerned, it will use the powertrain of the Niro EV, which means two battery packs will be on sale – with 34 kWh or 60 kWh. The larger of the two should provide a range of approximately 300 miles (485 kilometers) between two charges.”



“Volkswagen Group China is beginning construction in Anting of the Group’s first factory specifically designed for the Modular Electric Drive Kit (MEB) platform. The first model that will be produced in the factory of SAIC Volkswagen will be an electric Volkswagen brand SUV in 2020.” according to Green Car Congress: “Together with the FAW-Volkswagen factory in Foshan, which opened this summer, SAIC Volkswagen’s plant will begin to produce e-cars on the MEB platform directly after the first worldwide MEB-production starts in Zwickau, Germany.” Herbert Diess, Chairman of the Board of Management of Volkswagen Group, said: “Through Volkswagen’s MEB platform, we will be able to easily produce state-of-the-art electric vehicles for our Chinese customers on a high scale. The Volkswagen Group, its brands and their Chinese joint venture partners focus consistently on sustainable mobility and push the transformation of the automotive industry in China and worldwide. In this way, we emphasize the importance of the Chinese market for the Volkswagen Group.” “The facility is scheduled to be put into production by 2020 with a planned annual capacity of 300,000 vehicles. It will produce various new pure electric vehicles of SAIC VOLKSWAGEN, including medium- and large-sized pure electric SUVs, as well as battery systems. The factory will be supporting the Volkswagen Group’s e-mobility strategy in China. The vehicles being produced in Anting are based on the MEB, which is Volkswagen’s first pure electric automotive modular platform developed for mass production. ”

Barcelona – Checking out EV Chargers

Driving around Barcelona finding electric vehicle charging

My reason for going on these road trips in Barcelona to find and test these electric vehicle charging point is this. When you are in a hurry and driving from the airport with a carload of people you don’t want to waste time looking for charging points which are not going to work for you. That’s one reason anyway. Another reason is just because I wanted to go on a road trip and drive my car just for fun. It’s a good excuse to have a day out with my 2018 Nissan Leaf to go for a drive to Barcelona.

On this occasion I didn’t go into the centre of Barcelona. I stayed to the area north of the city. My first port of call was to Granollers to check out a charger listed in the PlugShare app. This was my first disappointment for the day. The charge point looked new and unused. I wasn’t able to use it either. The charger has been situated in the street, but has not yet been commissioned for drivers of electric vehicles. If I get a chance on give it another try in a month or two.

I looked on PlugShare to find out where was the nearest rapid charger to the one in Granollers. The nearest was only 23 minutes away in Santa Perpetua de Mogoda. So I set off using Waze GPS to guide me. It wasn’t too difficult to find although I did have to go to the next roundabout and turn round to come back to spot the entrance to the car park. The signpost for the electric vehicle charging was only visible from one direction.

This was a good place to stop in a car park for public buildings, there was a library and other buildings for the inhabitants of the town. I was able to use the library to perform a call of nature. I then went for a walk around the town and found there were plenty of café’s, restaurants, bars and supermarkets. This is useful if you need to get supplies or to get food & drink.

Apart from the rapid charger with the CCS and the CHAdeMO there was another charging post with two Type II charging sockets. At least if the rapid DC charging was unavailable for whatever reason you could still try the other charging facility. I used the Barcelona Live electric vehicle card to activate the rapid charging point. The other charging post had QR codes which you scan with your phone in order to activate.

I did need to stay too long at this charger and decided I would carry on to the next one I wanted to investigate. The next one is at Barbará de Vallés and one which is also close to the motorway. Either of these two charge points will be useful when taking a trip to the Barcelona airport. Both are handy to pull in and add a quick charge to make sure I have enough juice to get all the way home.

When I pulled into this next charger there was a Renault Zoe already using the rapid charger. I pulled up in front and I was prepared to wait for a short while. The driver was finished he is charging all decided he had enough and would be moving on. He could have just been being a gentleman to allow me to plug in. I gave him a friendly wave as he exited the charging point. This charge point was situated in a more industrial and busy area. I stayed for long enough to test the charging. I was only pulling in about 20 kW into the battery of the Nissan Leaf.

Another electric vehicle charging point to try and a place to go and have something to eat. I decided to drive to the IKEA furniture store. The food in the restaurant there is not too bad and there are a number of Type II charges you can use while walking around the magical mystery tour. It always takes a long way to walk around the maze which IKEA have constructed to make sure you walk past all of their products on sale. I ended up buying a few bits and pieces. When I got back to the car, Rosie the 2018 Nissan Leaf was fully charged. I was ready to drive back home.

The only stop I planned to make on the way back home was in Vidreres. This is a small town not far from the junction where you leave the motorway which goes towards Girona and head instead towards the beaches of the Costa Brava. St. Feliu de Guixols and Platja d’Aro. If I had missed out on all of the charging opportunities before and was getting low on electrons when I was not far away from home, Vidreres would be a good place to stop. It’s a fast charger and not a rapid charger, but good enough to put in sufficient kilometres in a fairly short time. I was glad to pull in and rest my eyes which were getting tired from the driving. The stop gave me a chance to stretch my legs even though there’s not much nearby the charging point worth walking to. 15 minutes at this electric vehicle charge point and I was ready to continue driving. I arrived back home with about 63% in the battery.
