EV Wallbox: A Guide to Choosing Your Home Charging Station in Germany
As more and more people in Germany are opting for electric vehicles, having an EV wallbox at home is becoming essential for EV owners. There are many different types of EV charging stations available, each with varying charging speeds and connectivity options. In this guide, we'll walk you through everything you need to know to choose the right charging station for your needs.
What is an EV Charging Station?
An EV charging station, also known as a charging point or EVSE (Electric Vehicle Supply Equipment), is a device that supplies electric energy to charge an EV. It is similar to a petrol station but for EVs. EV charging stations come in different types and charging speeds, so it's important to choose the right one for your needs.
Why is Choosing the Right Charging Station Important?
Choosing the right charging station is crucial for a smooth charging experience. The right charging station should provide enough power to charge your EV in a reasonable amount of time. It should also be user-friendly and come with features like connectivity and an app to monitor and control charging. Choosing the wrong charging station could lead to longer charging times, higher electricity bills, and even damage to your EV's battery.
Why you should get a Level 2 Home Charging Station
If you're looking for a quicker way to charge your electric vehicle (EV) at home, a Level 2 charging station might be the way to go. These charging stations are a bit more complicated to set up and must be installed by an electrician, but they come with a Type 2 charging cable in Europe and plug into a 240V outlet.
With a Level 2 charging station, you can charge your EV 3 to 7 times faster than with a Level 1 charging station, depending on your car and the charger. For example, a Level 2 charger can add 25 miles of range to a Nissan Leaf in just one hour of charging.
It's important to keep in mind that a Level 2 station is more expensive than a Level 1, but it's faster and more convenient, making it a great option for overnight or daytime charging. Just remember that 22Kw chargers require a three-phase power supply.
However, it's worth noting that Level 2 charging stations are not the fastest option available. Level 3 charging stations, also known as DC fast chargers, can charge an EV up to 80% in as little as 30 minutes, but they are much more expensive and are usually not suitable for home use. Level 2 charging stations are a good compromise between charging speed and cost, making them a popular choice for home charging.
Key Features of Level 2 Charging Station:
- Offer faster charging times compared to Level 1 charging stations.
- Equipped with a Type 2 charging cable, it ensures compatibility with most European EVs.
- Ideal for daytime or overnight charging.
Cost and Installation of Level 2 Charging Station:
- Pricier than Level 1 charging stations.
- Require professional electrician services for installation, adding to the overall cost.
Portable EV Chargers vs. Wallboxes
Portable EV Chargers:
- Designed for portability and convenience.
- Lightweight and compact for easy transportation.
- Come with a universally compatible plug for connection to any power outlet.
Wallboxes (Electric Vehicle Supply Equipment or EVSE):
- Provide a more permanent charging solution.
- Typically installed at home or in the neighbourhood and connected to a dedicated circuit.
- Offer faster charging rates than portable chargers.
- More expensive but provide unmatched convenience.
Wallboxes come with different connectivity options that allow you to connect the device to the internet and access features like remote control and monitoring, status updates, and firmware updates. Some models (Wallbox Pulsar Plus, Heidelberg Wallbox Home Eco and others) ****come with Wi-Fi connectivity, which allows you to connect the device to the internet. Some of the wallbox come with an Ethernet port for wired internet connectivity, while some come with cellular connectivity, allowing them to connect to the internet without Wi-Fi or Ethernet. Wallboxes with Bluetooth connectivity let you connect the device to your smartphone or another Bluetooth-enabled device for remote control. Some wallboxes come with RFID (radio-frequency identification) capabilities, which allow for contactless access control for authorized users.
The simplest wallboxes let you charge your vehicle at a fixed power level and might not do much more. Cheaper versions do not have a fixed cable with a plug but only a socket where the user must plug in their cable. One of the crucial features of a wallbox is connectivity (by hardwiring, WIFI or 4G). Most importantly, this enables switching the charger on remotely either instantly or by scheduling charging sessions. It might also enable you to adjust the power level, see charging statistics and open charging for anyone via different authorization options. Having an app for all these functions eliminates the need for a display on the wallbox.
