Can I switch to electric for €450 a month?


What are the costs of running an EV per 100km? I'm thinking of buying the new Hyundai Kona or Ioniq 5. I spend an average of €450 per month and maybe I can replace this costs with monthly payment on a new car. Also what would be the costs of buying and installing a charging station at home. Kind regards Nelson

Hi Nelson,

OK, as ever our answers here include a certain amount of ‘it depends…’ as much does indeed depend on your driving style, the ambient temperature, the cost of your electricity at home and how much public charging you need to do. But, roughly, this is how it should all break down.

Let’s start with the Kona — and by the way, these are both excellent choices as the Kona and the Ioniq 5 are amongst the most impressive EVs on sale right now. Hyundai officially claims that the Kona Electric has consumption on the WLTP test of 14.9kWh/100km, but we’re going to be a little more pessimistic, or realistic perhaps, and assume that you’ll achieve more like 18kWh/100km.

At that rate of consumption, you’ll — obviously — burn through 18kWh of electricity for each 100km you cover. On its undercounted rate for electricity, Electric Ireland will charge you 21.9c per kWh, which means that you’ll pay €3.93 in electricity costs for each 100km journey, assuming you do all of your charging at home.

What if you’re not charging at home? Well… If you’re using one of the new very rapid ESB chargers, which cost 37c per kWh, that cost obviously jumps a bit. In fact it goes up to €6.63 per 100km. If you’re using an IONITY 350kW charger, without a discount or membership, you’ll pay 73c per kWh and that pushes the price up to more than €10 per 100km.

However, the likelihood is that you’ll be using a mix of all three, and maybe you’re lucky and can charge for free at work, so let’s stick a finger in the air and average it out at around €5 per 100km journey. That’s just for the electricity cost.

If you go for the Ioniq 5, then we reckon that you’re looking at more like 20kWh per 100km in day-to-day use, which gives you costs of €4.36 (home charging), €7,37 (ESB rapid charging), or €14.54 (IONITY). Again, all of these prices are to an extent moving targets, and can be reduced further with discounts on charging and home energy bills. Or with free or subsidised at-work charging.

Of course, there are not total life costs. You have to factor in the costs of buying the cars themselves — Hyundai currently has an offer for the Kona Electric of €254 per month on a PCP plan, or the Ioniq 5 at €380 per month.

Those are both for the basic models, but that’s actually OK — the base Ioniq 5, with the smaller battery, is actually quite a canny buy as it will still do a reliable 360km on one charge, and doesn’t look nor feel all that much different to the ritzier versions inside or out. Assuming a reasonable cost for insurance (never an entirely safe assumption to make…) I reckon we can get you in under the €450-per-month mark for either car, with the Kona obviously having a bit more headroom for costs.

The cost of the charging station at home is even more difficult to answer with surety. There is a wide variety of home chargers available now, at various price points, though of course you should be eligible for an SEAI rebate, too. The unknown is if any additional work needs to be done to your house's electrics. Take a read of our Charging your electric car at home feature for a little more detail on that.
