The government today announced the "Roadmap for the Popularization of Electric Vehicles in Hong Kong", which will stop new registration of petrol vehicles before 2035.
In order to achieve that all newly registered vehicles will be electric vehicles after 2035, Hong Kong still has a lot of work to be done.
Cheng Jiawei, a professor of electrical engineering at the Hong Kong Polytechnic University, known as the "father of Hong Kong-made electric vehicles", believes that Hong Kong must fully use electric vehicles. In addition to the problems of charging and parking spaces that are often mentioned in the past, maintenance personnel and old battery disposal , And even the society’s knowledge of electric vehicles needs to be improved.

According to the figures of the Transport Department as of December 2020, of the approximately 570,000 licensed private cars in Hong Kong, only about 17,000 are electric vehicles, accounting for about 2.6%, while the 3,965 private cars registered for the first time in December 2020 , Only 817 are electric vehicles, accounting for about 20%.
It is still more than ten years before all newly registered vehicles are electric vehicles. Zheng Jiawei believes that during this period, different issues need to be dealt with in stages, including the maintenance of electric vehicles in the future and retraining garage mechanics.
Zheng said that gasoline vehicles use mechanical engines, but electric vehicles use electronic parts, and maintenance personnel have become electrical maintenance personnel. "Point retraining transition? Cultivate a new batch of double E graduates? In the next 30 years (The government) What to do."
Experts expect that electric vehicle maintenance personnel may need more than 10,000 people in the future to train and take time
According to the road map announced by the government, the authorities indicate that they will closely liaise with tertiary institutions to plan appropriate courses in advance.
Zheng predicts that in the future, electric vehicle maintenance personnel may need more than 10,000 people, and the training of talents will take time. It should be implemented as soon as possible. "University courses must be approved for at least two years before successful, and four years of university studies, that is, the fastest is done today, and the fastest is 6 years There are graduates first."
The roadmap also pointed out that the Vocational Training Council currently has courses covering electric vehicle expertise and maintenance technology. It will study and promote cooperation between electric vehicle suppliers and local institutions to launch more electric vehicle maintenance courses and provide retraining opportunities for mechanics. The EMSD Vehicle Maintenance Technical Advisory Committee will also ensure that the VTC courses can meet the needs of the industry.
Zheng Jiawei pointed out that some firefighters feel a headache about handling electric vehicle fire alarms.

Personnel dealing with emergencies such as the fire, police and highways departments must have relevant knowledge
At present, the original factory is mainly responsible for repairing electric vehicles. However, Zheng expects that in the future, car owners will choose to go to the garage for repairs. How to deal with the old batteries and old parts is also a problem. How to deal with it? The problem does not appear immediately. It will happen first in 10 years. Should it be dealt with first?"
In the future, in addition to electric vehicle maintenance personnel, it is necessary to master the structure of electric vehicles. Cheng Jiawei pointed out that personnel from the fire department, police and highways departments also need to learn about electric vehicles.
He said that firefighters once told him that facing electric vehicles is "a headache." Before traditional fuel vehicles are flooded with water, the firefighters will cut the car battery wires to avoid short circuits.
However, there are many types of electric vehicles. The batteries are placed in different positions, and the voltage can reach hundreds of volts, which is also a test for firefighting.
Commercial vehicles are the most difficult to deal with charging problems
There is no timetable for electrification of large commercial vehicles such as trucks and buses. The road map only refers to a comprehensive review of the situation in 2025.
Cheng Jiawei pointed out that the problem of charging commercial vehicles is the most difficult, so he has also studied whether charging facilities can be installed at traffic light positions and stops. It’s recharged again.”
To achieve zero carbon emissions in Hong Kong, Cheng Kar-wai believes that there is still a lot of work to be done. "It takes many stages for the whole Hong Kong to have electric vehicles on the street." He hopes that after the government releases a timetable, the citizens and organizations can have ideas. , There are corresponding preparations, "Don't make a deadline, people just do it lazily."
