The seven deadly sins of trams, not environmental protection ranks first?

Akio Toyoda chose to reject electric vehicles while choosing to join the electric car camp very honestly.

Choosing to cooperate with BYD is a manifestation of wanting to live, even so, Akio Toyoda will bombard the problems of electric vehicles many times in public.

One of the problems is that if there is a large-scale switch to electric vehicles, the power network will collapse, at least for the Japanese market, and the annual sales of several million will be a major test of the power network.

In addition, Akio Toyoda said that electric vehicles only transfer the environmental pollution load, not directly from the engine to the atmosphere emissions, the battery does not directly emit pollutants to the atmosphere, but the battery scrap utilization link is difficult to deal with, water sources, soil are direct pollution.

Theoretically, the tram is indeed more environmentally friendly than the petrol car, because it consumes renewable energy, the sources of electric energy are diversified, and the working mode of the battery is very low compared to the simple and crude consumption of oil.

But this only exists at the theoretical level, and the important thing is that the pollution of batteries is actually more terrible.

The European market has long discovered this problem, and the implementation is who sells and who disposes, and the scrapping and reuse of batteries must be controlled. Failure to do so poses a huge threat to the environment.

Previously, some overseas institutions said that electric vehicles actually produce higher pollutants than gasoline vehicles in many scenarios.

For example, due to the fast acceleration from the start, the wear of the tires is more severe, and the amount of suspended particles is several times higher than the pollutants emitted from the exhaust pipe.

In order to control this problem, tire manufacturers need to independently design special tires for electric vehicles, in which the wear coefficient should be strictly controlled, because the characteristics of fast acceleration of trams will occur frequently in daily use.

From the perspective of the entire process of production, manufacturing, use and scrapping, the total emission pollution of fuel vehicles is properly controlled, mainly because the industrial chain tends to be perfect, and the transformation, waste storage and sorting process is reasonable.

The improvement of the industrial chain needs to be driven by profits, and fuel vehicles have an independent and complete recycling, utilization, and remanufacturing process.

According to expectations, in 2023, new energy vehicles will produce about 150,000 tons of power batteries, and a total of 450,000 tons of power batteries will be eliminated by the end of the year.

At present, the dismantling and utilization system of power batteries is not perfect, and many power batteries are still in a state of abandonment.

In 2023, the production of new energy vehicles in the domestic market will reach 9.58 million units, a huge increase, which will be a huge gain point for the entire industry, according to the average 15-year service life of electric vehicles, the first batch of new energy vehicles that entered the official sales period in 2014 will fully enter the phase-out period after 5 years.

In addition, due to the newly built supplier system, including but not limited to charging piles, tires, motors, and power grid systems, it will be comprehensively improved with the increase of the market share of electric vehicles.

In the process of iteration of new and old technologies and hardware, due to the inability to form a complete and reasonable form of industrial chain reuse, this means that these parts will be abandoned.

Tram is an industry sector, not only need excellent electric vehicles, but also need a perfect treatment system, from production, sales, use to scrap and reuse of the entire link, all need to control pollution emissions, especially for some backward cities, how to make trams and household electricity effectively docking is very important.

Most of the community does not have the ability to charge, although the enterprise side has a strong technical performance, for example, household electricity can also be installed DC charging piles, but the premise is that the community power grid supports high-power charging piles, and many communities can not even install 7kW charging piles.

Tram sales have indeed risen, but the whole ecology is not perfect enough.
