Among most EV charging connector types, CHAdeMO stands out as a notable option, especially for certain types of EVs. But what exactly is CHAdeMO, and why should you care about it? Let’s dive into the details and explore everything you need to know about this charging standard.
CHAdeMO Level 3 EV charging, introduced by Japanese car makers in 2010, stands for “charge for moving.” It uses a special plug to deliver direct current (DC) to an electric car’s battery, bypassing the onboard charger for faster charging. The CHAdeMO standard supports up to 400 amps, with new high-power versions delivering up to 200kW.
How does CHAdeMO work?
To use CHAdeMO charging, you connect your car to a charger with a special plug. The charger sends DC power straight to the battery, cutting down charging time. Most CHAdeMO chargers can fully charge a car in less than an hour, perfect for quick stops on long trips. The CHAdeMO protocol helps the car and charger talk to each other. This makes sure the right amount of power goes into the battery based on its status. It also has safety features that stop overcharging or overheating.
In addition to its fast charging capabilities, CHAdeMO supports DC metering, which allows for precise monitoring of energy usage during charging sessions. This feature ensures that both the driver and charging station operators can accurately track the amount of electricity consumed.
Which EV Car Can Use CHAdeMO?
Many Japanese car makers use CHAdeMO EV charging. These include Nissan, Mitsubishi, Subaru, and Toyota. They have added the CHAdeMO standard to their electric cars for fast charging. Several popular electric cars use CHAdeMO EV charging. The well-known Nissan Leaf uses this standard. Other models are the Mitsubishi Outlander PHEV, the Toyota Prius Plug-In Hybrid, and the Lexus UX 300e. These cars charge quickly with CHAdeMO.
Advantages of CHAdeMO
One big advantage of CHAdeMO EV charging is its speed. It sends high power directly to the battery for fast charging. This is handy for drivers who need quick recharges and is popular where many people drive electric cars.
CHAdeMO EV charging has many safety features for both cars and users. The protocol keeps the charger and car in sync to avoid problems like overcharging. Plus, the design of the connector reduces electrical risks during charging.
What is the Maximum Voltage for CHAdeMO?
The CHAdeMO standard supports a maximum voltage of 500 volts. This high voltage capability is one of the reasons why CHAdeMO chargers are able to deliver fast charging speeds, making them a popular choice for EV owners who need a quick recharge. The 500-volt capacity allows the system to efficiently deliver power to a wide range of electric vehicles, ensuring that they can get back on the road quickly. This makes CHAdeMO an ideal option for public charging stations and busy areas where fast turnaround times are essential.
CHAdeMO vs. CCS (Combined Charging System)
CHAdeMO and CCS are used in different places. CHAdeMO is common in Japan and Asia. CCS is more used in Europe and North America. CHAdeMO only does fast DC charging. CCS can do both AC and DC charging from one port, making it more useful. CHAdeMO has a separate plug for charging. CCS uses one plug for AC and DC. CHAdeMO can charge a car to 80% in under an hour. CCS can do this in less than 30 minutes, so it’s faster. Both CHAdeMO and CCS chargers give high power for quick charges.
CHAdeMO vs. Tesla Supercharger
CHAdeMO works with cars like the Nissan Leaf and Mitsubishi Outlander. Tesla Superchargers are made for Tesla cars but adapters let other cars use them too. To use Type 1 and 2 charging with CHAdeMO, you need an adapter. CHAdeMO charges cars quickly but Tesla Superchargers are even faster, taking about 20 minutes to reach 80%. Both have safety features to stop overcharging or overheating. Tesla Superchargers have more stations, especially in North America and Europe.
Cost of Using CHAdeMO Chargers
Pricing Options
- Pay-Per-Use: Most CHAdeMO stations charge you based on the amount of electricity you use, typically ranging from $0.20 to $0.40 per kilowatt-hour, though rates can vary depending on the location and provider.
- Subscription Plans: Some networks offer monthly or yearly plans. For example, a typical monthly plan might cost around $20-$30 and offer unlimited charging sessions or significant discounts on each session, making it an economical choice if you charge frequently.
- Membership Discounts: Joining specific charging networks, like EVgo or ChargePoint, can offer discounts of 10-20% on charging sessions, helping to lower your overall costs.
Comparing Costs with Other Charging Methods
- CHAdeMO vs. CCS: On average, CHAdeMO charging costs about 10-15% less than CCS. For example, a 30-minute charging session might cost $ 5-$10 with CHAdeMO compared to $10-$15 with CCS, depending on the network and location.
- CHAdeMO vs. Home Charging: Home charging typically costs between $0.10 and $0.15 per kilowatt-hour, making it cheaper than public CHAdeMO stations. However, while level 2 home charging is slower, adding around 20-30 miles of range per hour, it’s ideal for daily use and helps preserve your EV’s battery health. For example, overnight charging at home might cost just $5-$7 to fully charge an EV.
- CHAdeMO vs. Tesla Supercharger: Tesla Superchargers can cost between $0.25 and $0.50 per kilowatt-hour, depending on the location. While they charge faster, a full charge at a Supercharger could cost $18-$25, making CHAdeMO a more budget-friendly option for many drivers, especially when considering both cost and charging speed.
Why is CHAdeMO Being Phased Out?
Despite its early success, CHAdeMO is facing a murky future. In the U.S., the shift toward the North American Charging Standard (NACS) and the widespread adoption of the Combined Charging System (CCS) are causing a noticeable drop in new CHAdeMO installations. The automotive industry’s push for more universally compatible and advanced charging options is driving this change. Yet, CHAdeMO still has a role to play, especially for older or used electric vehicles, ensuring it remains part of the landscape for a while longer.
How to Find CHAdeMO Charging Stations?
Finding CHAdeMO EV charging stations is easy with online tools and apps. Websites like PlugShare and ChargePoint show maps of these chargers. Many electric car navigation systems also help drivers find nearby CHAdeMO stations, making travel planning simple.
CHAdeMO EV charging stations are found all over the world. Japan has many because Japanese car makers helped create them. Europe and North America also have many, but CCS chargers are more common there.
CHAdeMO Chargers and Adapters
For those looking to use CHAdeMO charging, understanding the available equipment is key. CHAdeMO chargers come in various power levels, suitable for different charging needs. Additionally, adapters are available for vehicles that need to switch between different charging standards, such as from CHAdeMO to CCS. These adapters provide a practical solution for mixed-fleet scenarios or when traveling across regions with different charging infrastructures.
Summary
CHAdeMO charging is fast and reliable for electric cars. Japanese car makers created the CHAdeMO standard, which has worked well for years. But other standards like CCS and Tesla Superchargers are challenging CHAdeMO’s future. Policymakers are discussing whether they should keep supporting CHAdeMO connectors. Even so, many EV owners still find CHAdeMO useful. Using CHAdeMO gives quick and safe charging, especially where it is common.
