Did You Know? Just Changing When You Charge Your EV Can Cut Your Electricity Bill by More Than Half

Today, "electric cars" have become part of everyday life for a new generation that cares about the environment and technology. But after switching from petrol to electricity, many people start asking new questions — especially about the electricity bill, which rises after installing a charger at home.

Many EV owners notice that their monthly electricity bill is quite different from before, even though charging at home should be "cheaper". This is where the popular question comes from — "When is the cheapest time to charge an EV?"

The answer doesn't lie in the brand of car or charger, but in when you plug in. In fact, the electricity authorities offer a special tariff called the TOU Tariff (Time of Use), which gives EV owners the chance to cut their electricity bill by more than half simply by understanding how it works and scheduling charging at the right time.

As specialists in EV Charger equipment, the EV Easy team will take you through the TOU system and smart charging techniques, so every time you plug in, you get the best-value charge.

What is the TOU Tariff? Why do EVs need it?

Normally, the standard electricity tariff we use is a progressive rate — the more you use, the more you pay, in steps. But for EV owners who need high power continuously over long periods, the electricity authorities — both the MEA (Metropolitan Electricity Authority) and the PEA (Provincial Electricity Authority) — offer a new option called TOU (Time of Use).

TOU charges different rates depending on the time of day, divided into 2 main groups:

• Off-Peak (cheap electricity period): applies during times when demand on the grid is low, so the electricity authority charges a lower rate to encourage users to use electricity during this period.
• On-Peak (expensive electricity period): the time of highest electricity use in the day, such as early evening to night, so the rate is higher to help control overall demand on the grid.

For EV owners, charging a large battery over several hours uses a lot of electricity, so choosing to charge during Off-Peak hours is the most effective way to reduce costs.

A closer look at the Off-Peak hours you should know

Electricity authority

Days

Off-Peak hours (extra-low rate)

MEA / PEA

Monday - Friday

22:00 - 09:00 the following day

Saturday - Sunday and public holidays

All 24 hours

💡 Good to know: the Off-Peak rate can be as much as 4−5 times cheaper than On-Peak, depending on the type of meter and electricity contract you choose.

Simply schedule charging to match this period and you will see a clear reduction in your monthly electricity bill, without affecting your EV's performance at all.

Strategies for the most economical EV charging

Once you understand the time periods, the next step is to adapt your charging habits to TOU effectively. We recommend the following:

1. Charge only after 22:00

When you get home, plug in but schedule charging to start after 22:00 to get the Off-Peak rate.

2. Use the Delay Timer or Smart Charging function

Modern EV charging equipment, especially the models EV Easy imports and sells, comes with a charging timer (Delay Timer) or Smart Charging connected to a mobile app. Just set it to start charging automatically at 22:00 and you can relax without having to wait up to start charging yourself.

3. Fully charge at weekends

Saturdays, Sundays and public holidays are Off-Peak all day. Fully charging during these periods reduces your electricity bill the most.

Extra value and safety with a superior charging system

Having a Smart EV Charger doesn't just let you schedule charging to match TOU hours — it also comes with Load Balancing technology that manages household electricity use appropriately, without affecting other appliances.
