Range Anxiety? What’s that?

Range Anxiety? What’s that?

I am glad to report that range anxiety is only a short-term infliction for a novice EV driver. It took only two days to overcome the fear, which I realize know is born out of ignorance or a lack of experience. I feel so confident now that I am even prepared to take up a challenge to drive the 1400km to Johannesburg, which I estimate could be done in two days.

Granted, I am driving a BMW i3 REx, which can be classified as a plug-in hybrid (PHEV), giving you that added a sense of security. Over the last four days, I have only used the combustion motor on the first day to maintain the battery’s charge level, more our of fear than necessity. In fact, the American Environmental Protection Agency (EPA) devised a measurement, called a utility factor to compare how different PHEV’s are used. The utility factor is a projection of the share of miles that will be driven using electricity by an average driver in full electric or blended modes for PHEV’s. The Toyota Prius, for instance, has a utility factor of only 29%, while the Chevy Volt has a utility factor of 66%. The BMW i3 REx has a utility factor of 83%, supporting my experience.

Naysayers will try and detract potential or novice EV drivers by stating that an emerging market like South Africa does not have the necessary infrastructure of charging stations to support the adoption of EV’s. I was shocked that the sales manager of one of the large luxury brands used this argument on me today when I tried to find out what EV’s of PHEV’s they have locally. He argued his brand only supplied the best technological solutions. Really? Not a good claim to make if the only PHEV in the parking area was that of your competitor. I sometimes wonder why people, in general, depend on the word of a sales representative to make crucial buying decisions. This manager knew nothing about EV’s but he was prepared to take a position against it and most buyers would have based their decision purely on his knowledge. I digress. Granted, we do not have the fast charging network to support long distance traveling, but as mentioned in my post on range anxiety, only a few people need to travel more than 100km’s a day, at the least making the case for an EV as a second family vehicle. I found that there is no real need for charging stations to detract you from your buying decision. During this last week, I traveled 70km a day to and from work, leaving me with ample range to travel about three days in total before re-fueling. When home I plug the vehicle into my normal wall outlet overnight to recharge the +/- 10kWh I used. In any case, there is already some charging stations planned or being constructed in South Africa. A recent article estimated that globally charging stations would be a $12.6Bln industry by 2022, which would attract entrepreneurs or large corporates to provide the service locally.

Perceived high electricity rates impacting on charging cost is another favorite counter argument for EV’s. South Africans don’t like to hear that our electricity is cheap, however, compared to international standards it is still very cheap. Currently, the average base charge per kWh in Europe of 0.22 equates to R3.74 at the current exchange rate, compared to about R2.30 in Cape Town. Charging 10kWh would cost around R23, which is far less than the estimated R80 per day I spend on fuel for the same distance. WattEV2Buy provides a great tool to measure the cost of charging and comparing the cost for the different EVs and PHEV’s.

Another favorite argument by naysayers is that an EV’s battery pack only last for a couple of years and a replacing a pack are expensive. Most EV manufacturers currently provide an 8 year / 150000km warranty of the battery pack. Eight years is a very long time in the life of any technology. Added to which, if one take into consideration the huge increase in lithium-ion manufacturing capacity over the next three years, you can expect big price decreases in the kWh price of batteries. Just in the last year lithium-ion battery, cell cost decreased from above $600/kWh to $145/kWh negotiated for the Chevrolet Bolt battery pack from LG-Chem. Furthermore, a couple of business plans already exist for the second live of EV batteries as stationary solutions for grid or battery home systems. Both Nissan and BMW have already announced efforts to create second life products, giving some value to the battery pack when it needs replacement. Internationally efforts are also afoot to utilize EV batteries as part of the smart grid, providing EV users an income from their batteries for being a demand response asset when charging or even as backup power for one’s own home. There are even some manufacturers that lease the battery, so you would only buy the “shell” of the vehicle, Citroen and Renault provide this service. Some critique to this business model is that some drivers are skeptical that the vehicle could be disabled should they miss a payment.

I can honesty say that for me, apart from price there is no real argument for not switching to an EV or PHEV at the least. Elon Musk has done humanity a big favor by bringing EV adoption forward. It forced all the large manufacturers to review their EV strategies. Up to 2014, there was still widespread skepticism on the future of EV’s. If one review the vehicle manufacturers strategies in 2016 as summarized on wattEV2buy, it is clear that most have changed course for PHEV’s and EV’s. Now the majority of big auto brands have a planned product mix of around 50% PHEV’s and EV’s by 2020.

There is only limited time left to classify yourself as an early adopter, within two years the decision to buy an EV would be mainstream and promoted by the marketing departments of all automakers.

In the next blog we look at how to get the most out of your EV’s battery and extending range.

My first date with an Electric Vehicle

My first date with an Electric Vehicle

My first date with an Electric Vehicle.

The big day has finally arrived for my first date with and Electric Vehicle. I am not sure if it is a good or bad thing that my first date with an EV is an award winning luxury model. Fosdick’s BMW provided me with a BMW i3 REx, the range extending version in the BMW i3 series. The REx has the same 22kWh battery as the BMW i3 (2016) EV but with a 647cc combustion engine providing 38hp fueled from a 12liter fuel tank, the same engine as in the BMW 650GT maxi-scooter. The usable battery capacity in the BMW i3 is 18.8kWh. But enough of the technical jargon lets focus on what really matters! The driving experience and making the mind shift to an EV.

One experiences the starkest difference between a “normal” combustion car and an EV the moment you start the engine. When you start the EV there is no sound at all, it is the weirdest experience, you feel uncertain if anything will happen should you step on the accelerator. A golf car makes more noise once you get going, however to all the petrol heads that jokingly refer to a BMW i3 as a glorified golf car I can certainly attest that it is not. If one must compare the driving experience at that level, it will be a Scalextric car. The BMW eDrive system provides powerful torque and the responsiveness is immediate from a standing start. Although with this type of driving you see your battery deplete very quickly. The driving experience is made even more direct thanks to the “one pedal feeling” that comes from a single pedal acting as both accelerator and brake. The low center of gravity provided by the heavy battery pack along the floor pan allows for superior handling.

One of the sales pitches that caught my ear was that there is no service required apart from tires and break changes, obviously with the caveat that the combustion engine in the REx needs servicing. If you consider that with the regenerative braking system much less breaking is required in traffic, resulting in longer lasting braking system.

The sales team was very knowledgeable and provided lots of detail on the car, but I would advise anyone that plans to purchase an EV to do their own homework also and ask relevant questions. For instance, does the package you purchase include fast charging, or is it optional? The BMW WallBox is also optional, BMW provides an assessment of your residents electrical system, which I will highly advise, but the WallBox comes with a high price tag. When I plugged the LV1 charger in my garage plug it tripped the electricity, after which I had to relay power from a plug point with higher amperage inside the house.

With the great tech included in the vehicle, the sales process is not just a “take the key and leave” affair. Connecting the vehicle to the BMW ConnectedDrive system unlocks a whole range of benefits and features. You can send reminders to buy milk or flowers from your laptop to your car or even active the horn, for what purpose I honestly don’t know. Back at my PC after showing the vehicle to some colleagues I was informed by the ConnectedDrive system that the passenger door was still unlocked. Comforts managed through the APP include Preconditioning, acclimatizing the vehicle for your preset departure time.

Through incorporating some gamification elements the APP measures your driving efficiency and compares it to the broader BMW i3 community, which leads to one’s natural competitive spirit kicking in, thereby successfully altering your bad driving habits. I actually ended up altering my route to suit the battery and become more efficient (I will explore battery management and increasing range in a separate post this week).

There are small technical things to take note of and get used to when driving the BMW i3 REx, like only being able to engage the range-extending mode once the battery’s state of charge (SOC) reaches 75%. A surprising thing is that you are not able to install a vehicle tracking system. However with all the connectedness I believe finding the car would be very much like “Find My iPhone”. Opening the fuel tank also requires a certain sequence due to the fire danger associated with the lithium batteries.

I can conclude that my first impressions of the BMW i3 and EV’s are lasting impressions, of the good kind. I already dread the day when I have to go back to a “normal” car. At least I can look forward to a couple of more days with the BMW i3.

Range Anxiety

Range Anxiety

Range anxiety is probably the most common hurdle to overcome for all new Electric Vehicle (EV) owners or prospective owners. Terms like “bricking”, used when your EV is as useful as a brick when running out of energy on the highway springs to mind. Well, I can certainly attest to the fear associated with range anxiety. I am test-driving my first EV next week, an awesome BMW i3, sponsored by the friendly folks at Forsdicks BMW Tygervalley.

The fear is keeping me up at night and remains with me in my waking hours over the last couple of days. The only time I experienced range anxiety in a diesel vehicle was when we took a safari in Botswana. We trekked for 3 weeks with no fuel available in a 600mile radius, and the fuel that was available was not of the required quality, clogging my fuel filter on the way back to Cape Town. But situations like that are extreme for most vehicle owners and they have to cast their minds back to a time when they were students to recall what range anxiety felt like. Having to fuel with the couple of cents that was left after a night out.

Questions like how far the distance between my office and home is, or how would rush hour traffic influence the vehicle’s range, consume my mind. Suddenly I also remember that the power in my house was not of the right amperage for the coffee machine I bought. At the time I did not know what it meant because I failed woodwork with Julius Malema. Now it’s all coming back to me, and I fully understand what amperage is, and that I sold the coffee machine for a reason – not having an amperage of 20amps on the plug points.

When I Googled “car charging stations in cape town” I had to scroll down on the result page, past Cape Cod and some other “Town’s” to find out that there are some in South Africa, being built in Sandton, a cool 1400km (875 miles) from where I live. How I wish I were back in San Francisco, where you had a better chance of finding a charging station than a petrol station in the city. When I did the calculations the BMW i3 would be perfect for my situation, it has a 128km (80 miles) range, which is more than enough for the 36.4km ONE WAY I have to travel to and from town. Suddenly my fear is amplified, as I realize it is equal to nearly 80km a day. What happens if the car is not fully charged when I leave home in the morning? I am also acutely aware that it is winter, and a battery loses its charge quicker in the cold.

Getting back to reality, and my date with a cool BMW i3 tomorrow. I recently read that a study by the US Department of Transport found that 95% of all single-trip journeys is below 50km (30 miles) and 98% below 80km (50 miles), with only 1% above 112km (70 miles). So it is clear that the vehicle manufacturers all targets this sweet spot with Tesla setting the benchmark on the longer distances, with a 400km (250 miles) distance.

I can also take comfort in the fact that BMW, the largest vehicle manufacturer in the world and its clever engineers will not design a product that will leave its driver’s with a car that is as useful as “brick”.

All I need to do to make the next week a great experience is to have a mind shift, from how vehicles were used up to now to how vehicles would be used from now into the future.

Follow my experience as a new EV driver with the BMW i3 over the next couple of days on wattEV2buy.com and join the revolution.

Quick Guide to Charging your EV

Quick Guide to Charging your EV

A quick guide to charging to charging your electric vehicle.

Charging your EV will remain the single most considered factor when owning or buying an EV. You can use wattev2buy.com to see what your EV’s mileage cost is depending on the electricity rate in your state.

There are 3 levels of charging your EV:

1.      Level 1 – Which essentially is plugging your EV into the mains. Depending on the EV’s battery specifications it can take up to 24 hours to fully charge your EV. Apart from the electricity rate paid to your utility, there is now additional cost involved for Level 1 charging. To fully charge a Nissan Leaf with a battery capacity of 24kW and a 2.3kW charge rate would take over 10 hours (24/2.3). Charging would put your electric system at risk in the long term as it would constantly be under full strain.

2.      Level 2 – Consist of a fast charger that can be bought extra with your EV. Different EV’s support different charging levels. The Leaf, for instance, has 3.3kW (or 6.6kW depending on country) onboard charger, the Ford Focus 6.6kW, and the Tesla Roadster 16.8kW. Again you will divide your battery capacity by the charging capacity to find the time to fully charge. Level 1 and 2 are ideal for city traveling and Level 2 charging stations are fairly cheap to install compared to DC fast charging stations.

3.      DC fast Charging (DCQC)– This charging station infrastructure is developed to deal with range anxiety and to support the use of EV’s over long distances. The DCQC charging option could add up to $700 on the purchase price of your EV. Various EV makes have various standard’s and therefore various adaptors. The standards are:

·        CHAdeMO, normally have a charge speed of between 40kW and 60kW. So charging a Nissan Leaf of 24kW/40kW = 36 minutes for a full charge.

·        Combined Charging System (CCS), a new standard with little penetration but an ultra fast charging speed of above 300kW in theory. Operational they only provide 60kW currently.

·        Tesla Supercharger is the company’s own improved DC fast charging standard with 120kW capability.
