Study Notes

Tensions Between Electric Vehicle Users and Residents

In July 2022, residents of Minh Apartment in Hanoi divided into two factions over a video showing an electric bike catching fire in a garage while charging.
The "electric vehicle faction" faced pressure as the opposing group proposed banning overnight electric vehicle parking and dismantling charging stations for safety reasons.
In August, a news article was shared that reported new regulations effective from August 1, requiring high-rated apartment complexes to provide electric vehicle charging points.

Growing Popularity of Electric Vehicles

Electric vehicles are gaining popularity in Vietnam for their cost-effectiveness and environmental benefits.
Infrastructure preparation, including charging station installation, is crucial to support this growing product trend from the green industry.
Many countries encounter a shortage of charging stations, prompting European nations to integrate charging points in garages of office buildings and residential complexes.

Fire Safety Concerns

Charging stations must comply with strict safety requirements to minimize fire risks, particularly given the larger battery capacities of electric vehicles compared to gasoline vehicles.
The probability of a fire incident from electric vehicles is low (0.0012% from 2010 to 2023), but if a fire occurs, it is challenging to control.
Traditional CO2 fire extinguishers are ineffective against chemical fires from battery incidents; specialized extinguishers filled with water-based solutions and foam are needed.

Current Infrastructure and Safety Measures

The resident, Minh, noted that while his apartment complex had charging stations, they lacked appropriate fire extinguishing equipment.
The smallest electric car battery starts at approximately 22 kWh, requiring significant charging time at lower power levels (up to 22 hours with level 1 chargers).
Level 2 chargers (7 kW to 19 kW) allow for quicker charging, achieving 90% capacity in around 3 hours; however, this requires a robust household electrical system capable of handling high currents.

Challenges of Electrical Demand

The substantial electrical demand of charging stations raises concerns about potential overloads and fire risks.
The stability of the electrical infrastructure is critical, especially during peak demand periods exacerbated by adverse weather conditions.
Balancing the need for electric vehicle charging infrastructure with safety and electrical system capacity is essential.

Recommendations for Implementation

Installing electric vehicle charging stations is necessary in Vietnam but should be approached cautiously, focusing on the actual infrastructure capacity.
Regulations for building charging stations should primarily apply to rest areas, as stated in Circular 09/2024 of the Ministry of Construction.
Careful and deliberate planning and implementation are required to meet the legitimate demands of electric vehicle users while ensuring safety.
