All About Batteries

We have put together a page to get you in the know from battery lingo to sustainability.

When you come to think about your electric car battery its time to think with a fresh mind.

Capacity:

Just like computers, mobile phones and TV’s, batteries are becoming much more efficient and compact. In relation to the mobile phones and their 40 year life span so far, they have dramatically changed and improved beyond what could have been thought comprehensible when they were first invented.

Batteries are still at the beginning of this cycle and are already capable of so much.

Not only are the batteries increasing in capacity, they are also able to charge with much more efficiency which pro-longs their life span.

When talking about batteries think of them like your fuel tank. You charge your battery up just the same as you fill up your tank. Then you use the contents of your battery to get from A to B just like you do with the fuel in your tank.

Battery Lingo: Battery capacity is measured in Kilowatt Hours. The easiest explanation we have found is….

 

“kW stands for kilowatt. A kilowatt is simply 1,000 watts, which is a measure of power. … A kilowatt hour (kWh) is a measure of energy. So a 1,000 watt drill needs 1,000 watts (1 kW) of power to make it work, and uses 1 kWh of energy in an hour.”

 

So the general rule of thumb is the bigger the kWh size for an EV battery the further it can go.

Below are some examples of EV battery sizes.

EV battery sizes

Kia Soul - 27kWh
Hyundai Ioniq - 28kWh
BMW i3 - 33kWh
Nissan Leaf 2018 - 40kWh
Renault Zoe 2016 - 41kWh
Hyundai Kona - 64kWh
Jaguar i-pace - 90kWh
Tesla Model S P100 - 100kWh

Degradation:

This has been a concern for many who are wanting to get an EV. But with battery technology leaping forward at a rapid rate degradation shouldn’t cross our mind again. There are many studies backed up with data to show that batteries are lasting a lot longer than anyone was expecting. Here is one below:

According to new data from Tesla cars they have seen less than 10% degradation on their batteries in over 160,000 miles. This should put anyone’s concerns at rest.

Charging:

Information about charging EV’s is a hot topic, we all want to know how long it will take to charge, where you can charge, what types of chargers you can use and so on. We have decided to create a dedicated information page all about charging so please click the button below for more information if we don’t cover your queries here!

The way we refuel will dramatically change when we transition to EVs. We will almost never have to go to a certain destination again to get more power unless you are on a long journey.

Here is one example of our future charging habits:

90% of the time we will be driving a routine journey from A to B (usually a place of work) without any real deviations. We know that this journey takes X amount of miles and our EV can easily do this without a full charge. Once we have done our routine journey for the day we will park our car up at home and plug it into the home charger. So for the time your at home your car can be charging up ready for your next journey.

Imagine that, every time you get into your car on the morning before going to work you have a full charge waiting for you. In theory the only time you would ever have to charge other than at your house would be the odd long journey you decide to take.

Then there is the charging capabilities.

Right now the most powerful chargers are Tesla Superchargers these have a capacity of 120kW per car however only Tesla vehicles can use these. The next best thing is Ecotricity fast chargers with a capacity of 50kW and you will find them at nearly every service station. 100kW chargers will be arriving to the UK very soon which is great to hear.

At home with a wall charger you can get a maximum charge of 7kW. To find out more about charging times go to our charging advice page.
