It’s so simple – Electric Vehicles are Cheaper to Run

How do 30 cents per liter of petrol sound?

That is the equivalent price you would pay to fill your Electric Vehicle (EV). To determine how you can save up to 80% on your vehicle running costs, check out our EV calculator here. EVs run exclusively on battery power and generally have a range of 120 to 450 kilometers.

Plug-in Hybrid Vehicles (PHEV) tend to have smaller batteries and a petrol generator backup and generally have an electric range of about 50 – 100 km but can travel a further 300 – 700 km on petrol. Both EVs and PHEVs can be plugged into the mains at home or the office. Most EV and PHEV users charge their cars at night, much like charging a mobile phone.

Please look at our New Zealand Electric Vehicle Buyers Guide to find out which is the right EV for you.

Charging at night also takes advantage of the off-peak pricing offered, like our ecoSAVER price plan. Charging also occurs during the day; this is commonly referred to as sipping.

Rapid Chargers are also being installed around NZ by Charge.Net.nz and will charge a Leaf from 0 – 80% in 20 minutes.

EV emissions vs. Petrol or Diesel

Choosing to switch to an electric vehicle is an easy financial choice; they are cheaper to run. But what about the emissions from an electric vehicle over its lifetime. Here’s an article that shows that EVs have 7 – 10 times more CO2 efficiency than petrol or diesel cars over their lifetime.161208-Pump-vs-Plug.jpeg

Below is a graph showing the various emissions of large and small cars and electric cars. Of course, if you are using an electric car and are an Ecotricity customer, you’ve essentially taken your vehicle fuel emissions to …. Zero!181101-EV-emissions-comparison-graph-figures.png



Country ecoNOMICS

The benefits of Electric Vehicles to New Zealand are immense. Here are some of the benefits of the Electric Vehicle revolution if 50% of the New Zealand vehicle fleet were to convert to EVs or PHEVs

  • We could import $2 billion less of oil per year.
  • We would save $370m in health costs per year.
  • We would be employing more people in New Zealand to produce more renewable electricity.
  • We could reduce emissions by a whopping 6 billion kgs of CO2 per year.
  • Fuel poverty would be a thing of the past.
  • Our streams and rivers would receive fewer oil pollutants.
  • There would be much less road noise!

Here are some other tips about fuel & Maintenance savings

  • Kiwi cars travel on average 39 km/day. This equates to approximately 14,000 km pa. An EV owner will save approximately $2,500 pa on fuel and servicing costs based on an average-sized petrol car based on the car owner.
  • If you spend $100 on petrol, you will spend about $20 – $25 on electricity to go the same distance in an EV.
  • EVs have regenerative brakes, so when braking or traveling downhill, energy is captured back into the battery. This also means that the brake pads on an EV may never need replacing.
  • An electric motor only has a handful of moving parts and lasts much longer than combustion engines; therefore, much has substantially lower maintenance costs.

Cost of EVs

-EVs initially had higher capital costs because this is a new technology. However, prices have already dropped significantly. The Nissan Leaf originally was $69,000 and is now $39,000 new, and on Trademe, second-hand imports are selling for around $15,000.

  • Considering the savings of $2,000 annually on fuel, these prices are now financially attractive for many.Charger-Images.jpeg160515-EV-charger-options-B.jpeg

Questions and Answers

  • EVs have maximum power from a standing start. They can accelerate quickly, and currently, New Zealand’s fastest street-legal car for a quarter-mile is an electric car beating all V8s.
  • The fastest production EV is a Tesla P100D which quietly reaches 100 km/hr in 2.5 seconds (Ludicrous Mode – Tesla Model S). Hold on tight!
  • You can now also buy an electric 4wd PHEV to fit the whole family in!
  • As noted above, EVs are faster than pedestrians expect, so please take care behind the wheel.
  • EVs are very quiet and emit about the same noise as a bicyclist. Some EVs emit synthetic noises at speeds below 40 kph. Over 30 kph, road and wind noise alert pedestrians about your approach.
  • Yes, you can. You can even drop the car end of the charging cable in a bucket of water and be completely safe. The EV and charger talk to each other, and the charger will only allow electricity to travel through the cable only if the EV and charger are communicating safely.
  • All chargers that Ecotricity sells are weatherproof and suitable for use outdoors.

EVs have no gears, so they feel like an automatic when driving and are very smooth when accelerating.

If you plug your car into a 10 amp socket, it will take about 4 hours to charge. If you have a dedicated 7 kW charger, it will take 1 – 2 hours to charge, depending on the type of EV you have.

  • EV batteries are different from mobile phone batteries as they are made up of several individually controlled battery modules. These modules use space-age technology to cycle battery modules to ensure long battery life individually.
  • You can typically charge your car as often as you like to keep the battery topped up. Studies have shown that using Rapid or Fast Chargers does not deteriorate EV batteries any faster than normal use.
  • EV batteries are expected to last about 8 – 10 years with the current technology but are improving and becoming cheaper over time.
  • Second-hand EV batteries can also be used for home energy storage. Replacement batteries for a Leaf in the US currently cost about NZD6,000. However, some manufacturers like Tesla are also starting to release replacement batteries with higher capacity/distance batteries than the original battery. So, your EV is like a fine wine, and it just keeps on getting better.
  • What happens if you run out of petrol? It is a nuisance. You will find that you will become accustomed to the range of your EV and use it accordingly. Driving style also affects your range; electric burnouts might be fun but not so cool if you have to borrow your mate’s power socket for a couple of hours to get home.
  • Carrying a charger that can plug into any 10 amp socket is a good backup.
  • Yes. Electric motors are very, very efficient. Think of how our electricity is delivered, transmission lines from all parts of the country and mostly renewable sources, and loses only around 10% in transmission losses.
  • Consider now the process of fossil fuels and how they are delivered.A. Drill a bottomless hole, sometimes offshore.B. Pump it to the surface, load it onto ships.C. Refine it (that uses a lot of electricity, by the way), ship it again.D. Truck to holding tanks, truck to petrol pumps.E. Electricity is then needed to pump the fossil fuel into your car.How much energy is required for all of this? A lot! Further, fossil fuel cars are only about 30-40% efficient when they burn the fuel.
  • The step into EVs is a massive step forward in technology, emissions, and savings for the consumer.
  • A fuel cell car is another form of an electric car, but instead of a battery, it has a hydrogen fuel tank. The inherent issue with hydrogen is that it needs to be compressed and stored under very high pressure. The energy required to compress is about 3 times as much as charging a battery, so not very energy efficient.
  • Additionally, most hydrogen is derived from fossil fuels, so it is not 100% step away from emissions.
  • Talk to any EV or PHEV owner, and they will not stop raving about them, especially the fuel savings and acceleration.
  • In EV surveys, customers rate their EV vehicles higher than fossil fuel cars.

Very. Now, time to go shopping for one.

Remember, when you buy an EV, be sure to lend it out to friends and family to spread the word.
