• Operate effectively in all climate conditions: Electric vehicles have the ability to operate stably in many different weather conditions. The Battery Thermal Management System (BTMS) helps maintain optimal battery performance in both hot and cold weather.

Daily Travel Distance

Estimating the average distance traveled per day is the first and most important step in choosing a car with the appropriate battery capacity. The range of electric vehicles has improved significantly in recent years, with many models capable of traveling over 400km on a full charge.

Examples of operating ranges of some popular electric vehicle models:

• VinFast VF e34: 285 km (according to NEDC standards).
• Tesla Model 3 Long Range: 568 km (according to WLTP standards).
• Hyundai Kona Electric: 415 km (according to WLTP standards).
• MG ZS EV: 320 km (according to WLTP standards).

Note that actual operating range may be 10-20% lower than the published figure, depending on usage conditions such as speed, terrain, ambient temperature and air conditioning use.

When choosing a car, consider a range that is 30-50% higher than your daily travel needs to ensure there is enough "backup" for longer trips or in case the battery cannot be charged. every day.

Charging System

Understanding the charging system is an important factor when owning an electric vehicle. Currently, electric cars can use three main types of chargers:

• AC Charging Level 1 (slow charging): Use a regular 220V power source at home, capacity about 2.3-3.7 kW. Charging time can take 20-30 hours for large capacity batteries.
• AC Level 2 charger (average charger): Usually installed at home or work, capacity from 7-22 kW. The battery can be fully charged in 6-8 hours.
• DC charging (fast charging): Has a capacity of 50 kW or more, can charge 80% of the battery in about 30-60 minutes. Usually installed at public charging stations.

When choosing to buy an electric vehicle, consider accessibility to the above types of charging stations, especially home charging installations and the location of fast charging stations on frequently traveled routes.

Price and Cost of Ownership

When making the decision to purchase an electric vehicle, it is necessary to consider the total cost of ownership (TCO), not just compare the initial purchase price. TCO includes vehicle price, operating costs, maintenance and incentives. Specifically:
