Introduction: The Accelerator of EV Growth
Have you seen many EV players in the industry? Recently, Elon introduced the Tesla truck. Tesla isn’t the only one leading the charts in the EV manufacturing industry. Instead, BYD has emerged as a prominent player.
Even though many top companies, such as Geely, are also in the EV race. When selecting an EV vehicle, you must consider the EV charging stations.
But two types of chargers come into action— Ac and DC. Both are different. Have different charging speeds. For example, Ultra fast DC chargers beat the AC ones in the charging speed.
Why? Today, we will discuss the reason behind the ultra-fast charging speed of DC chargers. Let’s discuss it in detail.
Section 1: Distinct Roles of AC and DC Charging
You might wonder about the AC and DC charging systems and know the differences that lead to the speedy and slow charges. Do you want to know how AC charging is slower than DC? Let’s discuss.
AC Charging
In AC charging, the energy from the grid gets converted from AC to DC for storage in the batteries. This process utilizes the onboard charger of vehicles that have less power. Therefore, the charging speed is slower than that of DC charging systems.
Such a system is ideal for residential or workplace slow charging scenarios.
DC Charging
Fast DC chargers have revolutionized the charging game. They convert the AC into DC externally instead of relying on the internal vehicle chargers. The external conversion occurs through a powerful system with advanced technology and better charging speed.
Such a system is designed for high-speed charging on highways and commercial applications.
Fundamental differences in power transmission and technical architecture
Once you understand both charging systems, you can spot the ultimate difference in both options.
It is all about the power transmission.
- AC chargers harness the vehicle chargers for conversion. These have limited power and reduced charging speed.
- DC chargers utilize an external system with high power and advanced electronic technology. It leads to effective processing of the current and power.
The ultimate result is the high power transmission and faster charging speed.
Section 2: Why is DC Charging Faster? From Technical Principles to Practical Performance
There can be many other reasons that empower the system and favor the fast DC chargers.
Here is the list to better understand this system.
Direct Power Delivery
The power conversion from AC to DC is a big setback as it loses power. Moreover, the board chargers further lose energy due to bottlenecks.
What if you bypass the whole system? Congrats!
DC charging bypasses the vehicle’s onboard converter, delivering power directly to the battery. It minimizes the bottlenecks and offers fast charging options.
Power Level Advantage
High power means faster charging. If there are constraints, you might be unable to fetch the required charges.
AC chargers operate at 3.7–22kW. Most of the power operations are limited by the onboard chargers. Now, DC power operates from 50kW to 350kW. If you have a compatible EV, this ultra-fast DC charger can charge devices to 80% within 15-20 minutes.
Such a high power advantage allows the EV charging stations to empower vehicles with fast charging solutions.
Hardware Differences
How DC chargers support high-power transmission with advanced features:
- Liquid cooling. The high-power charging can heat the whole system. However, the DC chargers have changed this game by offering cooling systems, such as liquid cooling.
- Intelligent load management. Smart load management offers seamless load distribution across various charging stations and channels. Therefore, you get the quality handling of power without wasting it.
- High Capacity Converters. High capacity offers load handling even at higher power levels.
Section 3: Charging Needs Across Different Scenarios
Different systems require different technological aspects. As a result, charging needs are different at this point.
Private EV Owners and Public Charging Stations
Suppose you are traveling miles away. If you are in a hurry, you can’t afford to lose the battery and need faster charging. How would you cope with this situation?
Ultimately, your eyes will be on the ultra fast DC chargers. They offer quality solutions and deliver extended performance. The latest EV charging stations will deploy this technology for faster and more effective charging.
Commercial Fleets and Shared Mobility Platforms
The fleet managers need one thing— speed of charging!!
DC chargers have reduced this problem. Are you wondering how? Operational efficiency is the critical aspect. The DC charging system offers empowered solutions by reducing downtime. It also decreases the overall latency of the system and kills all the extra expenses in a minute.
Logistics and Warehousing Applications
The logistics and warehousing industry is at its zenith. Do you know why? Because of extended eCommerce operations.
Hundreds of vehicles transport products from one region to another. As a result, you have to consider EV charging for different vehicles.
Faster charging can reduce changing times and allow seamless vehicle operations.
