EV Wall Chargers


Firstly, do you charge every day? Consider a wall charger for charging at home. Electricity-thirsty vehicles increase the wear and tear on your wiring and a wall charger is designed for daily use. Using a wall charger with 32 Amp rating allows for a quicker charge. For charging times see our Charging Guide.

It depends on the distance you drive every day and on the time you have to charge your car.

You can either use a cable (Mode 2) with either a 3-pin plug or a caravan plug, or we recommend using a wall charger/home charging station (Mode 3). Both options simply deliver household electricity to the car. Electronics on board the car transform the domestic power supply (AC) into the proper form (usually DC) to charge the battery. The car also has a maximum power rating which means, depending on the wiring it can only take 15 amps as an example with a Nissan Leaf.

Please note: Not all charging cables are created equal. OEM Audio only sell EV Power EVSE which has safety features to help protect your car and property from, for example, fluctuations in the supply. All instructions must be followed for safe use. All EVSE should be purchased from a supplier who has met all the accreditation requirements as set out by WorkSafe. 

We reckon the first step before buying EVSE is to determine which option suits your needs best. Take a look at our EV Charging Products Finder, call us or pop in. Our reception staff will greet you in our showroom and our Technical Manager will help you choose the right product for your car. We've been selling EV charging products since 2016 and stand by our products and reputation.

We recommend that you engage a registered and licensed electrician to check your household wiring.

We don't charge for a phone call and welcome your call for advice. 


Wall Chargers have a few different names around the world. You'll see Home charging stations/home chargers/home charge points or wall boxes advertised. These all refer to the same thing.

EV home charging stations are generally firmly mounted on the wall. The electricity goes through a box and a cord that improves safety by waiting to send power to the plug until it’s plugged into an EV. A home charging station/Wall Charger is preferred over constant use of your 3 pin plug outlet and will require wiring a dedicated circuit to have safe charging. 

Charging Safety

Constant charging from a power socket at home can lead to wear and tear and possible overheating. Also note that many manufacturers, such as Nissan, recommend using a Wall Charger.

An OEM Audio EV Power Wall Charger offers peace of mind with many safety features and the initial expense should be factored into the cost of the car. OEM Audio stocks the EV Power 16 Amp, 11kw Wall Charger, Three-phase, RFID Tags, supplied with DC detection. This means you can avoid purchasing a Type B RCD separately. Standards New Zealand website states "...Where an EVSE is installed at a residential installation, the charging final sub-circuit shall be protected by a Type B RCD and the sub-circuit shall originate from a MEN switchboard." See more about safety standard SNZ PAS 6011:2021 for EV Charging here.

Charging Time

EV Power Wall Chargers will enable higher powers than the EV Power charger cables, supplying 240V, (like what an electric dryer or oven uses). Consequently, the charging time is faster. On average, an EV Power or EO Wall Charger can reduce charging time in half. Understanding the time you need to charge your vehicle will help you select the right EVSE.

Charging challenges

EV Power and EO Wall Chargers also solve a number of charging problems.

If you will have two rechargeable cars in the household in the future or want to be able to have your friends recharge at your house when they visit then OEM Audio have the solution. 

A basic Wall Charger has no user authentication. These are best for use where only you have access to the Wall Charger. Controlling access to the power supply can be achieved by using the EV Power 16 Amp, 11kw Wall Charger, Three-phase, RFID Tags, supplied with DC detection tags. This Wall Charger will only operate for approved users with a matching access card. 

Once you find a charger that best fits your needs, we recommend contacting a licensed electrician to install your charging station. The licensed electrician will need to know what amperage panel needs to be installed, to support the power requirements of your charger. Chargers deliver a high level of electricity for many continuous hours every day. Therefore, it is extremely important that it is installed correctly.
