Home charging solutions

Home charging stations are usually categorized as level 2 chargers. Level 2 chargers have higher power levels and charging speeds compared to level 1 EV chargers. But using a level 2 charger is more complicated than using a level 1 charger.
With a level 1 EV charger, you only need to connect a normal household socket, whereas before using a level 2 EV charger, you need to consider whether you want to install another socket. Therefore, you need to hire a professional electrician when installing a level 2 home electric car charger to ensure that the charging station is safely integrated into your home's electrical system.

1. Communication protocols:
The charging station communicates with the electric vehicle through a communication protocol. This protocol ensures the safety and compatibility of the charging process. For example, SAE J1772, CHAdeMO, and GB/T20234.2-2021.

2. Charging authorization and authentication:
Some charging posts require charging authorization and identity verification. This can be done through R, mobile apps or other means of authentication to ensure that only authorized users can use the charging post.

3. Charging process:
When an electric vehicle is plugged into the charging station, a communication protocol is initiated between the charging station and the vehicle. This communication protocol acts like a command to indicate that the electric vehicle charging station can be turned on in power supply mode. The charging process is then initiated via the vehicle's on-board control system or the charging station's user interface. Once charging begins, the home charging station delivers AC power to the electric vehicle. For this reason, home level2 EV charging stations are called AC EV chargers.
During the charging process, the charging post typically continuously monitors the EV's battery status and makes adjustments as needed. Some charging posts are also equipped with a remote monitoring feature that allows users to remotely monitor the charging process through a mobile app or web interface.

4. Completion of charging and disconnection:
When the battery of the EV is full or reaches the target set by the user, the charging pile will stop supplying power and complete the charging process. Users can also monitor the charging situation through the app or stop charging in advance.

Charging at home is potentially more cost-effective than using public electric vehicle chargers. The economic differences between charging at home and using public charging stations involve considerations such as electricity costs, equipment expenses, and additional fees.

There are two main expenses associated with charging an electric vehicle at home: the cost of purchasing a home electric vehicle charger and the electricity charges. Firstly, electricity costs need to be taken into account. If your residential area offers time-of-use (TOU) plans, you can take advantage of charging during non-peak hours to reduce electricity costs. For instance, utilizing the scheduling feature of a home electric vehicle charger allows you to charge during the late night or early morning when rates are lower.

Installation costs are another factor to consider. Home charging involves the purchase and installation of charging equipment, while public charging stations are provided by operators, eliminating the need for individual equipment purchases. However, in the long run, consistent use of public EV chargers may accumulate charging fees that surpass the cost of purchasing a home electric vehicle charger.

Charging service fees are also worth noting. Some public charging stations may impose additional service fees, whereas charging at home typically does not incur such extra charges. Understanding these factors is crucial for a comprehensive assessment of the economic differences between home charging and public charging stations.

The common types of home electric car chargers are level 1 and level 2 electric car chargers.
Electric vehicle chargers are mainly divided into two types: alternating current chargers (AC chargers) and direct current chargers (DC chargers). According to the use purpose, electric car chargers are divided into home electric car chargers and commercial electric car chargers.
AC chargers (level 1, level 2 EV charger):

AC EV chargers are divided into level 1 EV chargers and level 2 EV chargers.

Level 1 EV chargers:
Voltage: typically operates at standard household voltage, 120 volts AC in North America.
Charging Power: Provides a slow charging rate, typically charging about 2 to 5 miles per hour.
Application: Level 1 chargers are typically used in residential environments for nighttime charging or where extended charging times are acceptable.

Level 2 EV chargers:
Voltage: typically 240 volts AC.
Charging Power: Level 2 EV chargers typically have a power output in the range of 3.3 kW to 22 kW, with 7.2 kW and 11 kW being more common.
Application: Level 2 chargers are typically installed in residential environments, but are also common in public charging stations, workplaces and commercial locations. They are suitable for every day charging needs and can significantly reduce charging times compared to Level 1 chargers.

Level 3 EV chargers (DC fast chargers):
Level 3 chargers are designed for fast charging in commercial and public places. They are often used as public EV chargers and deployed in scenarios such as motorways, petrol stations, fleets, etc. to meet people's fast charging needs.

Choose the right home electric car charger.
When you buy an electric car charger, you will find that there are many types of electric car chargers, and they have different power, charging speed and smart features. Therefore, you need to choose the right electric vehicle first, making sure to buy a charger that is fully compatible with your electric vehicle model. You can consult an EV charger dealer for this step and they will be happy to assist you.

Know your home electricity system:
In general, electric vehicle chargers typically require 240 volts of power, while data from the U.S. Energy Information Administration (EIA) shows that the typical American home has a power capacity of 200 amps. Therefore, before installing electric chargers, you need to consult a professional to ensure that your home electricity system supports the operation of electric vehicle charging stations.

Properly install home electric car charger:
Follow the installation guide provided by the EV charger supplier for the installation steps to properly install your home EV charger. Having a professional electrician install it is a good choice.

Check the condition of electric car charger and cable regularly:
You need to check the condition of the charger and cable regularly to make sure they are not malfunctioning. Keeping your electric car charger in good condition will help extend its service life and ensure a safe charging process.
