What is the most comfortable way to charge the EV? The wall box DC charger market is booming to power both: personal and business supplies. If you are considering setting up the best EV charger for your family or company so you can start your day with a full battery every day, this article is for you.
What is a “Wall Box”?
Wall box DC charger is an electric vehicle charging station that provides direct current power to an EV battery. It is called a "wall box" because it is actually mounted on a wall or a post and designed for home or business use.
How fast are wall box chargers?
Overall, EV charging is available in different power levels or modes, ranging from 7 kW to 350 kW. The power level determines how quickly you can power an EV. Higher power levels are typically found at public charging stations or commercial locations, while lower levels are often used in homes or workplaces.
Classification of EV charging modes
There are three main classifications of EV charging modes:
● Mode 1: This mode uses a standard household socket to charge the EV. It is the slowest and least safe charging mode, not recommended for regular use. Mode 1 charging typically delivers AC power at a low rate, ranging from 1 kW to 3.7 kW.
● Mode 2: This mode uses a dedicated charging cable plugged into a standard household socket. It includes additional safety features, such as a residual current device that protects against electrical shocks. Mode 2 charging typically delivers AC power at a higher rate, ranging from 3.7 kW to 22 kW.
● Mode 3: This mode uses a dedicated charging station connected to a fixed electrical supply. It provides faster charging speeds and is the most common mode for public and private charging stations. Mode 3 charging typically delivers AC power or DC power at a rate of up to 350 kW.
● Mode 4 charging is a term used to describe DC fast charging, which provides the highest charging rate for electric vehicles. It is also known as "DC direct charging" or "pantograph charging." These are the ones commonly used for commercial and public charging stations.
Mode 4 requires a dedicated charging station connected to a high-voltage DC power supply. This setup is typically used for fast charging along highways or in other areas where EV owners need to recharge their batteries quickly.
The fourth charging mode typically delivers DC power at a rate of 350 kW and charges an EV battery to 80% in less than 20-30 minutes. It's an ideal choice for long-distance travel or EV owners who need to recharge their batteries quickly. The wall box DC Chargers are essential components of the growing electric vehicle infrastructure.
Wall box DC vs. AC chargers
There are several reasons why someone might choose a wall box DC charger over other types of EV chargers:
Wall box DC chargers provide quicker charging speeds than AC chargers, so you can spend less time waiting for your car to charge. This is especially important for people who need to charge their car quickly or are on long road trips.
Wall box DC charging stations can be installed at home or work, so you can charge your car while you go about your daily routine. This is much more convenient than driving to a public charging station every time you need to charge your car.
Direct current chargers are more efficient than AC chargers, which means you can charge your car more quickly and with less energy. It can save you money on your electricity bill over time.
Compatibility with more vehicles:
DC chargers are compatible with a broader range of electric vehicles than other types of chargers. This is because they use a standard charging protocol that most EV manufacturers recognize.
Improved performance in cold temperatures:
DC chargers can maintain a higher charging rate in cold temperatures than AC chargers. The reason? DC charging bypasses the onboard charger in the EV, which can be less efficient in cold weather.
