EV Charging 101

Leave a reply Christopher Roberts

Following Jonny’s electric vehicle charging article, here’s everything you need to know about charging an EV in Europe – from someone who’s driven one since 2019!

First of all, fantastic work, you’re awesome!

Thanks for making a great decision and welcome to the future!

So charging, that’s something you need to do now… no more dinosaur juice for you, you’re EV all the way!

But how do you charge?

Types of Charging

Charging is really a lot simpler than you’d think, there are just two types:

  1. AC – Slow and Fast charging
  2. DC – Rapid charging

AC Charging

Slow Chargers

A slow charger uses AC power. Alternating current (AC) is what comes out of your plug socket at home.

In fact, plugging your car into a Schuko/3-pin plug, is an example of slow charging.

The charging lead (often called a granny charger, because of how slowly it charges) plugs into your home socket at one end and your car at the other. Some chargers and cars enable you to select how many amps to pull. A Tesla can pull between 5 amps and 10 amps from a domestic socket. You might want to vary the amperage if your house has poor electrics, or if you’re trying to use what your solar is generating.

So how much charge can a home plug socket provide?

10 amps x 230 volts = 2.3 kW (kilowatt)

The Tesla Model 3 Standard Range Plus has a 50 kWh battery pack, so on a 3-pin plug in the UK, you can charge half the battery (or 25 kWh) in 11 hours. That’s over 100 miles topped up on cheap, renewable electricity while you sleep.

Fast Chargers

Fast charging also uses AC power. If you get an EV chargepoint installed at home, it is likely to be a 7.4kW fast charger.

This would enable you to completely “fill” a Model 3 from empty to full in a little under 7 hours.

Fast charging speeds are limited by the cars onboard charger. This converts the AC power into DC power, to feed into the car’s battery.

Charging by AC and DC

Some BEVs (battery electric vehicles) have powerful onboard chargers, like the Renault Zoe, which can charge at up to 22kWh. The Model 3 has a 11kW onboard charger. Some cars are limited to slower speeds, like the VW e-Up! limited to 7.2kW AC charging.

Many supermarkets and retail parks have fast chargers onsite – which are often free! Spending 60 minutes in the supermarket can give you ~40 miles of charge.

DC Charging

Rapid and Ultra-Rapid Chargers

Rapid (and Ultra-Rapid) charging uses DC power. This means the power can be fed straight into the battery.

Rapid chargers can charge from speeds of 43kWh, to speeds upwards of 350kWh!

If you’re on a long road trip, you’d use a rapid charger to top-up the battery at super speed!

The Tesla Supercharger network is an example of an ultra-rapid charging network. Many Supercharger stalls now have 250kW chargers! A Long Range Model 3 can charge at up to 250kWh, which is over 1,000 miles an hour!

Using the Supercharger network, you can top-up 200 miles of range in 15 minutes. That’s 3 hours of motorway driving in the time it takes you to visit the toilet and get a cupa tea.

Rapid chargers tend to be more expensive than Slow and Fast chargers, but they can deliver power at much faster speeds.

Rapid chargers are sometimes supported by battery storage, to ensure consistent supply and the cleanest possible energy. Here’s a video of the GridServe charging hub from the awesome team at Fully Charged.

Charging Plugs

European charging connectors are also really simple now.

European AC connectors for Slow and Fast charging are:

  1. Type 2 (AKA mennekes)
  2. Type 1

European DC connectors for Rapid charging are:

  1. CCS (AKA Combo 2)
  2. CHAdeMO

CCS and Type 2 use the same plug design – CCS is basically a Type 2 plug with an extra two pins.

A CCS plug (left) and a Type 2 plug (right)

Both have been the standard socket in Europe for some time now, with CHAdeMO and Type 1 slowly being phased out.

Some charging posts have more than one type of connector – using the right one for your car will ensure you get the best speed! For example, using a Type 2 charging lead will charge much slower than a CCS lead – if your car has both sockets.

Many charging units can charge more than one car at a time, but not all, so it’s worth checking beforehand.

Generally speaking, Slow and Fast chargers (away from home) don’t come with a charging cable – you plug your own in. Rapid chargers however always come with a cable – be that CCS or CHAdeMO.

Finding a Charger

The UK has more charging stations than petrol stations, so it’s not difficult to find a charger. To help you out (in the UK) Zap-Map have a fantastic live, interactive map! PlugShare is a similar map, which covers most of the world!

How many chargers are there within 10 miles of your home?

I bet it’s more than you thought!

The Electric Future

Today I present to you the first in a series of posts on electric vehicles! Everything you’ve ever wanted to know about driving an electric car – because since September, I have been!

An electric car charging

EVs (or BEVs) are the future. Hydrogen, fuel cell, biofuel and battery electric drivetrains all offer exciting opportunities for the future, but it’s the electric car that’s gathered the most momentum so far. In the first 6 months of 2019, around 800,000 fully electric cars were sold globally, a figure that’s increasing exponentially each year. Those 800k cars added to the 3.3 million electric cars already on the road at the end of 2018.

EVs being the chosen form of future transport is largely down to one man and one company – Elon Musk CEO of Tesla. In fact, it’s the Tesla Model 3 that’s been credited by many as the driver (if you’ll excuse the pun!) of EV adoption growth.

Since its release, it’s dominated the market in the United States and was the 9th best-selling car in 2019. That’s not the 9th best battery electric vehicle (it was the most popular EV) it’s the 9th top-selling car overall! It tops its class selling more small and medium-sized luxury cars to the USA market than Mercedes and Audi combined.

Sales of electric cars in general have been rapidly gathering momentum around the world. Norway is leading the way, where 42% of new car sales in 2019 were BEVs.

The Netherlands is also a trailblazer in the electric future, with the Tesla Model 3 (a fully electric car) claiming the most sales of any car in 2019. In December, 54% of new cars sold in the Netherlands were plug-in electric vehicles (different from battery electric vehicles, as this also includes PHEVs) up from 15% in 2018.

The UKs electric market is also gathering pace, with 7.3% of cars sold in 2019 having a battery and electric motor – so this includes BEVs (100% electric vehicles), PHEVs (plug-in hybrid electric vehicles) and HEVs (hybrid electric vehicles). The BEV market share has more than doubled from 2018s 0.7% market share to 1.6% in 2019 – with 3.3% of cars sold in December fully electric. That could skyrocket next year, as Benefit-in-Kind tax (BIK) becomes 0% on EVs from April.

95% of Global New Car Sales Will Be Electric in 2030 - poll of 174 EV owners

In my final article of the 2010s, I made some predictions for 2030. One was that in 2030, 95% of new cars sold (globally) would be battery electric vehicles (EVs). I’ve polled 174 current EV owners to get their view on the 95% prediction and turns out, on the whole they agree! The majority (53.5%) think it is likely, with only 28 people saying it’s very unlikely.

You could argue that EV owners are a biased sample, as they’re already living the electric future and won’t want to go back to owning an ICE (internal combustion engine) car, but it’s important to take into account that they are living the limitations of owning an EV too. They understand the challenges of charging, range and existing (breakdown, servicing etc.) providers not understanding the technology.

Based on my knowledge of current uptake, I believe 25% of global new car sales will be EVs by 2024. Bloomberg analysis indicates it won’t be until 2028, with it taking another 10 years until EVs finally de-throne ICE (internal combustion engine) vehicle, topping 50% of sales. In my view, that’s overly pessimistic and I think Bloomberg will be surprised by the rate of acceleration this decade.

We’ll have to wait and see.

Exhaust fumes coming out of a car

Many countries have already moved to ban internal combustion engine cars, with Norway leading the way, phasing out petrol and diesel new car sales by 2025. The country is set to have all cars running on green energy in five years time. The UK has also set a target – albeit a little less ambitions – of 2040 for the ban.

Data suggests global charge point installations have started to rise significantly, 80,000 units installed globally in 2012, 180,000 in 2015 and 630,000 in 2019. Tesla currently have 1,800 Superchargers installed around the world with over 15k individual stalls (or pumps for you ICE fans!) although as these are paid for by Tesla funds, they’re exclusively for Tesla cars.

In order for EVs to be a viable form of transport, destination charging infrastructure is critical. Unlike fossil fuel-powered cars, it’s rare you need to “fill-up” an electric car while out and about, since charging at home and work gives most people enough juice to do their daily driving. Rapid roadside chargers are important too (like Tesla Superchargers, the IONITY network, and Ecotricity) especially for those looking to do more than 200-miles, which is the range of most electric cars.

Over the next few months I’ll be sharing my experience of driving an EV, debunking EV myths and explaining key terms. Hopefully, if I do a really good job, I might even persuade you to make the switch yourself!

Some bold predictions for 2030

Hello all!

I’m back!

Just in time to see the year (and decade) out! 😊

I’ve been working on a series on electric vehicles, which I’ll start to publish in the new year. Today though, I’m going to look into the future and make some predictions on what the world will look like 10 years from now.

“Most people overestimate what they can do in one year and underestimate what they can do in ten” ― Bill Gates

In 2019, 2030 may seem really far away, but today, we’re closer to 2030 than we are to 2009.

Here are three bold predictions I believe stand a very real chance of coming true over the next decade.

95% of Global New Car Sales Will Be Electric

A decade ago, there weren’t any serious electric cars available on the market. If you played golf or delivered milk, you might use a short-range electric vehicle, but if you wanted to drive 400 miles at 70mph, it just wasn’t possible.

In 2012 the Tesla Model S arrived, as did the Supercharger network, which meant you could drive for 250 miles, stop for forty-five minutes on a 72kW charger and then drive another 150 miles, powered 100% by electricity!

This seemed like a breakthrough at the time, although today cars are available with almost 400 miles of range, and charging takes a fraction of the time, with some networks offering speeds of 350kW – juicing up at well over a thousand miles per hour!

Range has been creeping up, charging speeds rapidly improving and prices have dropped significantly. It’s now possible to pick up a second-hand 100-mile range Renault Zoe or Nissan Leaf for less than £7,000! Alternatively, the 2020 Renault Zoe will have a 200-mile range and cost around £25,000.

EVs require less maintenance than petrol and diesel-powered cars, and are significantly more efficient and cheaper to run – reducing the total-cost-of-ownership. It’s this, coupled with the push for cleaner air and global climate concerns that lead me to believe that the tipping point for electric cars is coming very soon. By 2025 I believe more than 50% of new car sold in Europe, North America and China will be powered solely by electricity. 🔋⚡🔌🚗

Humans Will Set Foot On Mars

In the 1960s there was a great race for space – with Neil Armstrong setting foot on the Moon in 1969. Since then, the dash for extraterrestrial exploration has slowed somewhat, which fewer advances and less drive from governments to get into space.

A notable exception is the ISS, which is celebrating 20 years in orbit – having been permanently manned since November 2000.

NASA has plans for a sustained lunar presence from 2028, something that’ll be much easier thanks to booming interest from the private sector. Rocket Lab, SpaceX and Blue Origin all have ambitious space plans, and a proven track-record of success.

Arguably the most iconic moment of the decade for space travel came as private enterprise SpaceX launched of its Falcon Heavy, simultaneously landing two Falcon 9 boosters.

Mars and Earth are close (in space terms!) every 26 months, meaning roughly every two years, there is an optimal launch window open for a trip to the red planet. The 13th of October 2020 is when the two planets will next be closest, although it’s highly unlikely a manned mission will be launched by then.

The last window of the next decade will the March 2029, which is when I’m guessing the first human will set foot on the red planet – 60 years after Neil Armstrong set foot on the moon.

While the first human to set foot on Mars will probably go straight from Earth, I believe a permanent lunar base will mean that most missions to Mars post-2040 will launch from the Moon, not Earth. This is because it’s likely to be far cheaper to conduct smaller launches from Earth and bigger ones from the Moon – due to the lower gravity.

If the moon has the resources needed for rocket fuel (ice at the poles which can be broken down into hydrogen and oxygen) and to make materials – via 3D printing – in future it could become the springboard to space! 🚀

10 Countries Will Be Cashless

More and more transactions are moving online. When you check-out your virtual basket of goods on the internet, you don’t have the option to pay with cash – one example of how notes and coins are less useful than they once were.

Sweden is expected to go cashless in 2023 and in many developed nations, the use of cash as a means of paying for things is dropping. In the UK, cash was king, accounting for 60% of all payments in 2008 and remaining the single most popular way to pay until 2017 – since then debit cards have been the most popular way to pay.

By 2028, UK Finance believes debit cards, direct debits and credit cards will all be more common ways to pay than cash, with cash accounting for only 9% of payments. The drop from 60% to 9% in two decades shows the scale of the decline.

On a recent visit to Singapore, it struck me just how far ahead it is in terms of payment methods. Everywhere I visited supported some form of virtual payments; from contactless on the MRT and in-app payments for taxis, to online payments for the hotel and card payments at a 7 Eleven.

Mobile banking, cryptocurrencies, online shopping and contactless technology all offer convenience and are alternatives to support a cashless future.

Naturally, in many parts of the world, lack of development and technological literacy, as well as nostalgia, habits and cultural preferences, mean cash will remain on the global stage for a while yet.

I do think around 5% of the world (10 countries) will become cashless in the next decade though – with Singapore and Sweden both likely candidates. 💷💳
