What is a Smart EV Charger?

Smart electric car charger

A truly smart EV charger considers the integration with future technologies and relieves pressure from our electricity grid.

Smart EV chargers in their simplest form are chargers which can be connected to the internet. The main purpose of this connection is to ensure that the device can be updated with firmware, especially as new software and technologies are released into the market, which may need to connect to the device.

Ultimately being smart, is future-proofing the device so that it doesn’t become defunct years down the line.

Intelligent EV Chargers

However, being smart as far as electric vehicle charging is concerned, is far more than just the ability to connect to the internet.

The new smart charge point regulations which came into play in June 2022, consulted on by myenergi, defines exactly what it means to be a smart EV charger.

Smart EV chargers ultimately have features that release pressure from the grid system, including Default off-peak charging, random delay at the start of a charge.

What kW car charger do I need at home?

Most Irish homes have a single phase AC supply and the maximum rate you can charge at on a single phase is 7kW. Therefore, 7kW chargers are most commonly used for domestic home charging.

Some modern developments are now feeding an AC three phase supply. If your premises does have a three phase supply, you can benefit from faster charger speeds and therefore could opt for a 22kW charger.

Therefore, 22kW chargers are most commonly used on smaller commercial premises, workplace or modern developments.

What is a smart EV charger?

A truly intelligent smart EV charger will also have the ability to integrate with other renewable energy sources such as solar panels, domestic wind turbines, battery storage and work harmoniously with elements such as air source heat pumps and wider renewable energy technologies around the building.

Other factors such as how it can save customers money through integration with time of use tariffs and economy tariffs should also be considered when selecting a smart electric car charger.

zappi is a popular choice for those looking for a truly intelligent smart charger as it ticks all the boxes of what is considered a smart charger.

zappi has been carefully designed to include several features and functions to give users complete control of their electric car charging experience, such as the ability to utilise time of use and economy tariffs, allowing users to schedule chargers at times when energy tariffs are at their lowest, thus encouraging energy consciousness.

Not only does myenergi design their products for the complete user-friendly experience but equally with the installation process in mind. Reducing face fix cabling and the need to reduce disruption to existing buildings was an important factor in the product design process.

Accessories such as the, harvi product is an energy monitor which transmits import / export data to the other myenergi devices every 1 second completely wirelessly and negates the need to run wired CT clamps between devices.

Which EV charger is right for me?

Untethered chargers

Untethered chargers come without a cable attached and instead you’d use your own cable, which is often supplied with the EV.

The main advantages with untethered chargers are : –

• Those with Type 1 vehicles would require a special Type 1 to Type 2 cable so would tend to opt for an untethered unit

• If you required a custom length cable, e.g. needed a 12m cable between the charger and the vehicle. (tethered units come with a 6.5m cable attached)

• They are aesthetically neater, subject to opinion

Tethered chargers

Tethered chargers come with a cable attached to the unit which cannot be detached. The cable has a Type 2 plug attached which has become the worldwide industry standard and is suitable for all modern EVs. (excluding a handful of early Type 1 models, hence if you have Type 1 you should choose the untethered unit)

The main advantages with untethered chargers are : –

• Convenience is the biggest benefit for choosing a tethered unit, negating the need to keep unpacking and packing away your detachable lead each time.

7kW chargers

7kW chargers are the most common car charger for a home charging station and would be the most suitable recommendation for existing residential properties and most new builds with a single phase supply.

22kW chargers

22kW chargers are the most common charger for smaller commercial and workplace charging properties with a three phase supply. However, some modern homes, especially new developments can opt for a 22kW charger if there is a three phase supply to the property.

What is fast car charging?

Fast car chargers are ultimately EV chargers which charge at rates between 7kW – 22kW AC. The process simply involves putting more electricity into your car’s battery at a faster rate. Where a typical 3 pin 13amp plug socket in the home would charge at the rate of 2.3kW, fast chargers charge at more than three times the speed. 22kW in comparison charge at more than nine times the speed.

• 2.3kW 3 pin plug socket (known as granny charging) – would take around 24 hours on average to fully charge from 0 – 100% (dependent on vehicle – note most Hybrids have very small batteries when compared to full EV’s)

• 3.5kW chargers (know as slow chargers) – would take around 16 hours on average to fully charge from 0 – 100% (dependent on vehicle – note most Hybrids have very small batteries when compared to full EV’s)

• 7kW chargers (known as fast chargers) – would take around 8 hours on average to fully charge from 0 – 100% (dependent on vehicle)

• 22kW chargers (known as fast chargers) – would take around 3-4 hours on average to fully charge from 0 – 100% (dependent on vehicle)

Fast chargers are not to be confused with rapid chargers or super chargers, which are the types of charger you’d use on longer journeys when you require a full charge in less than an hour.
