How Does the Ideal Home EV Charging System Look Like?
When buying a gasoline-based car, it has become commonplace to make sure you don’t buy one with fuel consumption that is too hard on your wallet and too harmful to the environment. In the same way, choosing the right home EV charging system is key to becoming cost-efficient and sustainable when it comes to electric mobility for individuals.
The multitude of different home car charging solutions for electric cars can be quite intimidating. It is worth taking a closer look to find the best EV home charging station for your needs. Learn about the details of electric car charging at home, including different types of EV home chargers, how to install a car charging point and how to charge EV at home.
Charging at Home
Home charging can be with a conventional domestic three pin plug or a dedicated charger, which is much more efficient. In the later case, charging is usually done via plug & play or RFID authentication.
EV Charger Installation
An EV charger installation at home needs to be done by a certified electrician and is completed within one working day. Most countries offer grants to cover part or all of the installation cost.
EV Charging Cables
There different types of EV charging cables and you have to make sure that it is compatible with your EV or buy an adaptor. Type 1 and Type 2 plugs are the most common plugs in EV home charging devices.
Best EV Home Chargers
There is a wide range of different types of EV home chargers, each with their own strengths and optimal conditions. We have determined the best home EV charging points in four different categories.
How to Charge Electric Car at Home
Home EV Charging - Quick Facts
- EV home charging is usually done via Plug & Play or RFID card.
- Domestic sockets charge EVs with 3kW.
- Single phase chargers deliver charging rates of up to 11kW.
- Three phase AC level 2 chargers are capable of 22kW charging.
- Smart chargers help to optimize energy flow and reduce electricity costs.
Generally, electric vehicle charging is a fairly simple process. As opposed to commercial EV charging solutions with different payment options, home EV charging systems almost exclusively use either the “Plug & Play” of RFID method.
There are important differences between a domestic charger and a dedicated EV home charger. Although both are fed by the public electricity supply, they differ radically in terms of charging rate.
Domestic Home EV Charging Systems
Most electric cars have a portable slow charger with a 3-pin plug for a domestic power socket. With 12 miles of range per hour at 3kW, this is the slowest form of charging. A full charge can take more than 24 hours with for EVs. Most manufacturers now recommend to get a wallbox installed for domestic charging, only using the 3-pin home electricity charger as emergency back-up.
INFO: Extreme charge/discharge cycles are problematic for lithium-ion batteries, which are used in EVs. Charging a battery to 100% and exhausting it down to zero will reduce battery capacity in the long term.
Therefore, EV manufacturers recommend charging to only 80 % of battery capacity. It doesn’t have to be exactly 80 percent; as long it doesnt reach the full 100%, the battery will be fine.
Why Dedicated Home Chargers Are Worth It
A 3.5kW charger usually suffices for home EV charging at reasonable speeds. However, the most popular chargers have a charging rate of 7kW. At this rate, you can fully charge a Nissan Leaf in just under six hours at this rate.
For charging speeds of 11kW or more, your home must have a three-phase power supply. However, most homes in the UK are only equipped with single-phase power, which is they can’t use three-phase chargers. You can apply for a three-phase upgrade through your grid operator, but this is very expensive, costing between £3,000 and £15,000.
EV charging at home can drastically raise electricity bills. There are options to mitigate this effect and smart home chargers offer effecive methods to keep electricity costs to a minimum.
Most electricity providers offer cheaper rates at certain times (called time of use tariff), so you can save money by properly timing your car charging. For our UK visitors, we provide a comparison of the best time of use tariff UK providers.
Smart Charging Through Intelligent Metering
Depending on the capacities of the chargepoint and EV, sustained high loads can quickly damage the circuits of either device. To avoid any damage to the main fuse, high-quality smart home chargers automatically balance the power drawn from the chargepoint with the energy flow of the house. This way, overloads to the charger will be prevented.
EV Charging Cables
There are different types of EV charging cables and plugs. Make sure you have the correct cable to charge your car. If your EV charger has a different plug than your car, you can use an EV charging adapter.
Types of EV Charging Cables
- Household socket: Standard 3-pin socket (max. output: 3kW).
- Type 1: Single-phase plug (max. output: 7.4kW).
- Type 2: European standard plug (max. output: 43kW).
- CCS/CCS2: DC fast charging plug. (max. output: 50 kW).
- CHAdeMO: Rapid charging plug (max. output: 400 kW).
What is the Best Electric Car Charging Station for Home?
Many electric car owners end up paying more than necessary because they did not precisely define their specific needs for their home EV charging system. User requirements should be the key factor when buying an electric vehicle charger while keeping the EV home charging cost to a minimum.
We sorted out the most common criteria for EV home chargers and compare EV chargers in the following categories:
- Best Home Car Charger – Overall
- Fastest Home Car Charger
- Cheapest Home Car Charger
- Best Hybrid Car Charger
Note that these are general recommendations that do not replace a detailed EV charger comparison that take your personal needs and cicumstances into account.
