Motor Expo 2026

Before getting excited about the range of an EV or rapid charging in just a few minutes, whether it's the BYD Dolphin, Aion Y Plus, Aion V, HYPTEC HT, or other models, before walking into a showroom or pressing the compare specs button, you must know these 3 things. Otherwise, you might fall into the trap of attractive numbers and be disappointed when driving in reality.

1. Understanding Testing Standards: NEDC, WLTP, EPA, and CLTC

NEDC (New European Driving Cycle)

Is an old standard tested in a laboratory with everything controlled, including speed, ideal weather conditions, no air conditioning used in the car, and no urban traffic. This results in figures that are higher than reality. Many Chinese car manufacturers still prefer to use this standard because the figures appear impressive.

WLTP (Worldwide Harmonised Light Vehicle Test Procedure)

Is a standard that simulates driving conditions closer to real life. It covers driving in large cities, suburbs, inter-provincial routes, and expressways, as well as changing seasonal weather conditions. This makes the figures closer to actual usage in Thailand.

EPA (Environmental Protection Agency)

Is a rigorous standard from the United States that covers urban driving, highways, acceleration, and fluctuating weather conditions. This results in figures 10–22% lower than WLTP but closest to actual driving. If you want conservative and reliable figures, EPA is the most trustworthy standard.

CLTC (China Light-duty Vehicle Test Cycle)

Is a standard from the People's Republic of China, introduced around 2021. It is designed for driving in heavily congested Chinese cities, focusing on stop-and-go testing at an average speed of 29 km/h. This results in range figures 15–25% higher than WLTP and 30–35% higher than EPA. Chinese car brands like Aion V and HYPTEC HT commonly use CLTC.

2. How AC vs DC Charging Differs

AC Charging

• Uses alternating current. Convenient, suitable for overnight charging at home.
• Typical power 3.7–11 kW (Wall Box 7–11 kW).
• Full battery charge 0–100% takes approximately 6–10 hours.
• Electricity cost is cheap, economical, around 4–5 Baht/unit. A single installation provides long-term use.

DC Fast Charging

• Uses direct current. High power, fast charging, typically public chargers.
• Power 50–150 kW (some models, such as HYPTEC and BYD, support up to 120–150 kW).
• Charges battery 10–80% within 25–45 minutes.

If you have private parking at home, it's recommended to invest in a Wall Box installation from the start. It saves 30–50% per charge compared to public charging and is much more convenient.

3. V2L (Vehicle to Load)

V2L is a feature that transforms an EV into a large backup power source, releasing energy from the battery through sockets in the car or an adapter in the charging port to directly power external devices.

Examples of V2L Usage

• If there's a power outage, you can immediately connect fans and refrigerators.
• For camping, conveniently charge laptops, connect speakers, or use an electric kettle.
• For construction work requiring electricity or selling goods at a market, you can connect electrical appliances directly.

EVs with V2L in Thailand (2026)

• BYD Dolphin and BYD Atto 3 (V2L cable included free in some promotions)
• Aion Y Plus and Aion V
• Neta V and Neta X
• HYPTEC HT (maximum power output 3,300 watts)
• ORA 5 EV (maximum power output 6 kW)

Before signing the contract, check if V2L is included as a standard feature or if an adapter needs to be purchased separately. Some brands include it for free, while others charge an additional 5,000–10,000 Baht.

Summary: To Choose the Right EV, You Must Understand These 3 Things First

Once you understand the differences between the various standards, AC and DC charging systems, and the V2L feature, you will be able to confidently choose a car that meets your actual usage needs, whether you're visiting the Motor Expo or a car showroom.
