As battery technology continues to develop, electric vehicles (EVs) are increasingly becoming our daily means of transportation. When purchasing an EV, one of the key considerations is how you will charge it and which appropriate charging device to choose.
The first decision usually revolves around whether to install a home charging station or rely on public charging infrastructure. Home charging stations offer comfort: you can charge your EV overnight to ensure it’s ready for daily commutes to work. A portable EV charger will be your best companion when traveling.
To select the right charging device, you need to consider parameters such as AC charging power, plug types, home socket type, charging distance (wall-mounted or portable), and other features.
1. AC Charging Power
Different car manufacturers offer various capacities for maximum AC charging power. Please first read through your vehicle’s user manual to obtain information on the maximum AC charging power. Typically, cars can accept charging powers in four steps:3.5 kW, 7 kW, 11 kW and 22 kW.
When selecting a charger, it is advisable to choose one that matches the maximum power your car can absorb. If the charger's power rating is lower than your vehicle's capacity, the maximum charging power will be limited by the output power of the charger. Conversely, if the charger's power rating exceeds your vehicle's capacity, the maximum charging power will be constrained by your vehicle's reception capability.
2. The type of charging connector (plug types)
Automotive AC charging connectors are typically divided into three types:
Type 2: European standard, vehicles manufactured in the EU use this standard charging connector
Type 1: American Standard. Vehicles imported from the USA usually use this standard charging connector.
GBT: Chinese Standard. Cars manufactured in China will use this standard charging connector.
Please open your car's charging port and check the type of your car's charging connector. When ordering a charger, please choose the appropriate type.
3. Socket Type
Chargers with different power ratings require different types of sockets. In the following, we only present the four common types of sockets.
3.5-kW charging device: 220 V, 16 A, EU Schuko socket, single-phase
7 kW charging device: 220V 32A CEE32A blue plug, single-phase (three holes)
11 kW charging device: 380V 16A CEE16A red plug, three-phase (five holes)
22 kW charging device: 380V 32A CEE32A red plug, three-phase (five holes)
It is recommended to choose a charging power according to the type of socket in your home or company. However, you can also use a high-power charging device with a low-power socket by adding an adapter. In the next blog post, we will provide a detailed introduction to selecting the appropriate accessories for the charging device.
4. Charging Distance
Please select the length of the charging cable according to the distance between the parking spot and the outlet.
Most buyers choose the standard cable length of 5 meters, which covers most daily charging scenarios.
If your car is parked in the garage, you can opt for a cable length of 3 meters, which is sufficient.
If the parking space is located outside the garden, you can select a wire length of 10 meters or 15 meters.
5.Wall-mounted or portable
The installation type of the charger can be divided into wall mounting (Wallbox) and portable.
We typically refer to a charger mounted on the wall as a Wallbox, which needs to be installed by a professional electrician, is fixed on the wall and cannot be transported in the car. The advantage of this type is that the power plug does not need to be pulled out, making it suitable for users who charge their vehicles at home for longer periods.
Another option is a portable charger that can be used at home and carried in the car to recharge the vehicle while working or traveling. And through the installation of fixed mounting accessories, it can also be used as a Wallbox.
Each charger has its own advantages, and we recommend purchasing a charger according to actual needs.
6 additional features
When purchasing a charger, we also consider other factors, such as whether it supports Wi-Fi/WLAN connectivity. By installing the app on your mobile phone, you can remotely control the charging data in real time. Since the charger has an input voltage adaptation function, different charging currents can be selected for various cars and socket types. And some chargers offer a charging light reservation feature.
