Smart charger or wallbox charger? And after you’ve made your choice, how do you put your charger? We respond to all of your inquiries regarding EV charging at home.
Over 80% of all electric car charging occurs at home, so it’s critical to have the appropriate equipment to make plugging in as simple, quick, and affordable as possible. This guide, which provides all the information you need on the various pricing options, was put together to make the procedure as simple as possible.
Are all chargers for electric vehicles the same?
When it comes to home charging, there are essentially two options: either utilise the sluggish charger that came with the car or have a wallbox installed. The former is easy to use and very portable, and it draws power from your household source using a conventional 3-pin connector. However, because battery sizes are constantly growing, it can take these units up to 24 hours to fully charge, which is why makers advise only using them in “emergencies.” A wallbox charger is a superior option, especially if you’re dedicated to regular EV use. It can be installed in a garage or on the side of your home to provide faster charging times in a safe and dependable manner. Moreover, it requires less cables to be run outside the house and is simpler to use.
A wallbox charger is what?
It functions essentially as an independent charger that is hooked into your residential energy supply. As the name implies, it is fixed to the exterior wall of your home and enables rapid and simple charging of your vehicle. Even better, there are “smart” units that you can remotely programme to only charge at specific times (like when your price of electricity is lowest) which may treat the battery to prolong its lifespan. These fast charging units will reduce the amount of time it takes to recharge the battery. Certain smart chargers can use this renewable energy if your home is equipped with solar panels, which will help you save money and reduce your carbon footprint.
Although there are also simpler and less expensive 3kW slow chargers available, the majority of wallbox devices are fast chargers that produce current at a 7kW rate.
If you want a wallbox, you will need a driveway, garage, or another type of off-street parking near to your home because you cannot extend the charging connection over a public pavement or road. Moreover, a skilled electrician will be required to install the wallbox.
How much does installing a home charger for electric cars cost?
This depends on the charging speed you choose and the “smart” features the charger should have. Simple 3kW slow chargers begin at about £100, while a speedier 7kW device costs about £300. Prices for “smart” appliances with wireless management through a smartphone app range from £450 to £1,000. Overall, the cost of installation is included in your purchase, but if extensive adjustments to your home’s wiring are required, there could be an additional fee. Even better, certain automakers are currently giving away a wallbox and installation when you buy one of their EVs, so it pays to look into the offers that are available.
What does a wallbox grant entail?
The government, through it’s own OZEV (Office of Zero Emissions Vehicles) division, is providing financial incentives to entice drivers to switch to EVs. Currently, if you purchase a new EV, you are eligible for a subsidy that covers up to £350 of the cost of a wallbox’s purchase and installation. For the time being, you are only eligible to apply for grants for two electric vehicles. The majority of homeowners with off-street parking, however, were no longer eligible to apply for the subsidy as of April 2022 due to amendments made by the government; now, only landlords, tenants, and small company owners were eligible.
How to create a home charging station for electric vehicles?
Arranging the assembly through the company that sells the wallbox is the simplest method. Often, the cost of installation comes with the purchase price, and the wallbox supplier uses its own network of certified installers. If you purchase the unit separately, you are free to select your preferred technician, but they must be authorised by the maker of the equipment you have selected.
It’s important to be aware that the installer will likely need to inspect your home’s electrical circuitry and your intended installation location before moving forward. Moreover, be ready to pay a little bit more for setup if you’d like the wallbox to be installed far from the fuse box or if your wiring needs to be upgraded.
How do smart chargers work and should I invest in one?
A smart charger is a wallbox which connects to several apps on your smartphone via Bluetooth or wi-fi. By doing this, it enables you to remotely customise the charging schedule for your automobile, allowing you to decide when charging takes place and the amount of electricity should be supplied to the battery. As a consequence, you can ensure that you only charge during the times when electricity is most affordable or cap the power in the battery at 80% to dissipate heat the cells and increase longevity. Although smart chargers cost more to purchase than ordinary ones, keep in mind that only this type of equipment qualifies for the government’s OZEV subsidy, making them more cost-effective to purchase in most cases.
Which wall charger can I buy for wattage?
The amount of current your charger can deliver will depend on both the wiring in your home and the on-board charging adaptor in your automobile. The cheapest option is the 3kW slow charger, that even with a small 40kWh battery vehicle like a Nissan Leaf can take 12 hours to fully charge, while larger vehicles like an Audi E-tron will take longer than 24 hours.
Compared to 3kW devices, the average wallbox provides 7kW of fast charging, which cuts the time in half. This rate of charging will be compatible with almost all electric vehicles, making it perfect for usage at home where most charging happens at night.
Additionally, there are 11kW and 22kW variants, however they need a three-phase power source, which is more common in commercial and industrial buildings than in residential settings. You can update your house, but it’s doubtful that the added expense would be worth the faster charging times.
Can I use a standard outlet to charge my electric car?
Most electric vehicles are equipped with a handheld slow charger that plugs into a domestic power outlet using a 3-pin connector. This is the slowest method of charging, with certain larger EVs needing and over 24 hours to fully charge. It charges at about 3kW. The majority of manufacturers now advise installing a wallbox for household charging and only utilising the 3-pin charger in an emergency. It’s also important to confirm that a cable comes as a standard, as some manufacturers don’t.
What is the rate of home electric car charging?
Most of the time, the fastest way to charge at home is using a 7kW rapid charging wallbox. With this unit, a MINI Electric could be fully charged within as little as three and a half hours, but a Nissan Leaf 40kWh would require more like six.
While household wiring is often single-phase, switching to a three-phase system can allow 22kW charging, which is even faster charging. A Nissan Leaf with a 40kWh battery could be charged up in as little as two hours if charging proceeds at this rate.
How do you tell if your connection is three-phase?
To determine whether your house has a three-phase electrical supply, the best course of action is to hire a qualified electrical expert to examine the wiring in your home. Yet, occasionally a short visual examination can indicate whether additional research is required. Since this is where the power supply enters the house, finding your fuse box and metre is typically the best course of action. A single big system fuse, a metre and a fuse box with circuit breakers for the different rooms and devices of the house are typically present with a single phase supply, as well as a single big system fuse. Three of such larger system fuses, normally each rated at 100amps, will be present in a three-phase supply.
What distinguishes a tethered charger from one that is untethered?
Simply put, this describes the kind of charging cable that is linked to the wallbox. If you only have one EV, a tethered unit is the best option because it makes charging easy—just park up and plug in. It has a permanently installed cable with a Type 1 or Type 2 connector.
While using an untethered unit, you connect it to the EV using the charging cable that came with the vehicle. This is a more flexible option since it lets you rapidly switch between Type 1 and Type 2 cables if, for example, you want to operate two distinct electric vehicle models with different connectors, like a Nissan Leaf and a Peugeot e-208.
Vehicle to Grid (V2G): What is it?
V2G (Vehicle to Grid) recharging combines an EV with national grid in a way that is currently only accessible to enterprises and a small number of retail customers. Energy suppliers can use the combined battery capacity for storing energy or connect their electricity for additional power during peak times when several vehicles are connected for extended periods at specialised V2G chargers (such as when stationed overnight or throughout the day even as their owners are at work). There are financial advantages for EV users and owners because the energy supplier pays for the power it consumes.
The next phase is vehicle to house (V2H) charging, whereby your car becomes a source of energy for your home. With renewable energy, this system could be very helpful because it will let you store electricity produced by solar or wind energy that would otherwise go wasted, for instance during the day when there’s a reduced need for lighting and warmth. The sole drawback is that only automobiles equipped with the CHAdeMO charging port can currently use this two-way energy flow. That essentially implies just Nissan products, including the Leaf and the EV200 van. But, a number of companies are almost ready to offer comparable technologies for the more well-known CCS charging method.
