The world's first metal-powered bus was successfully manufactured in Yunnan

Yunnan is making new energy vehicles, which is nothing new. However, the manufacture of a new energy vehicle supported by a new concept of “metal fuel” as a power system is definitely one of the highlights of the “first year of new energy vehicle development”. The reporter learned that the latest concept of "metal-powered cars" new energy vehicles, vehicle production will be completed in Kunming, Yunnan, the most critical part of the battery system will also be produced in Yunnan, can be said the world's first Metal-powered passenger cars, completely belonging to Yunnan descent. Chairman of China Zhide Group Co., Ltd. introduced that the car is ready to enter mass production. Compared with the most famous lithium battery electric car, the "metal power car" solves a series of problems such as excessive car price, short battery driving range and high cost of use.

The development of power systems for new energy vehicles is a problem that all car companies must overcome. How to find and produce efficient, stable and low-cost alternative products is the key to occupying the highlands. The insider's point of view is: In this new energy car manufacturing competition, all car companies are standing at the same starting line, and anyone who has this huge cake is likely to be divided. Naturally, Yunnan car companies are no exception. The reporter learned that the current metal-powered buses will be used in the Kunming public transport system.

Resource

Carbon-free metal fuel, rich in aluminum and magnesium

(PK results: all other metal batteries)

Tang Yougen, secretary-general of the China National Committee for Energy Storage and Power Supply and Materials, and director of the China Battery Industry Association, said that lithium batteries are among the most widely used and well-prepared products in the current research and development of electric vehicles. However, due to its high price, it is difficult to promote it in large quantities in electric vehicle power supply. This is one of the reasons why the price of electric vehicles in the auto market is too high.

In addition, lead-acid batteries are not likely to “go too far” due to low energy and secondary pollution; nickel-hydrogen batteries cannot meet the needs of electric vehicles due to battery energy density, cost and resources; Oxygen fuel cells have excellent performance and abundant resources, and there is no shortage of raw materials. However, hydrogen production, hydrogen storage difficulties, and Catalyst “platinum” have extremely low global reserves, making it difficult to commercialize in the short term.

The above is almost a new type of battery that is currently research and development, but no single battery can completely solve the contradiction between production and raw material supply. The carbon-free metal fuel used in metal-powered vehicles, magnesium and aluminum, is a kind of rich and cheap non-ferrous metal, and the price is low, which greatly reduces the cost in manufacturing and ultimately reduces the price of new energy vehicles. Installing several modules does not impose a heavy burden on the vehicle. Except for the general family car, even passenger cars and large tonnage trucks can be used. Tang Yougen said.

Cost

The cost of use is only 1/10 of the lithium battery

(PK results: cheap battery, easy to promote)

A carbon-free metal battery, like a lithium battery, needs to be recharged after it has been used up. In the interview, there is a question from the owner of the car. Charging is also a small expense. It is not necessarily cheaper than traditional cars.

Chairman Yu explained: "The first purchase cost of lithium batteries is not mentioned. The cost per kWh of lithium batteries is more than 5,000 yuan, and the cost per kWh of hydrogen fuel cells is higher. After the mass production of metal power systems is put into production, The cost of kWh can be controlled below 500 yuan, which is very competitive."

Effect

Single module driving mileage of nearly 1000 kilometers

(PK results: endurance wins, lithium battery is only 200 kilometers)

According to reports, the metal power module can support the vehicle to travel 1000 kilometers, while the lithium battery electric vehicle can only travel about 200 kilometers at a time. In terms of endurance, metal-powered batteries have obvious advantages, especially for the more complicated road conditions in China's western provinces and cities. Only 200 kilometers of endurance can not meet the needs of users.

"Because of the light weight of the battery itself, installing more modules will not impose much burden on the vehicle. Except for the general family car, even the bus and the large tonnage truck can be used." Tang Yougen said.

Environmental protection

Recycling completely carbon free

(PK results: no carbon concept, better than other products)

"Generally, reducing 1 kilogram of metal fuel requires only about 12 kilowatt-hours of carbon-free electricity, and 1 kilogram of metal fuel is equivalent to the work done by 2L diesel-powered conventional cars. It produces 2.268 kilograms of carbon dioxide per liter of diesel after burning. 12 kilowatts. When the electric energy reduction 1 kg of metal fuel can replace 2L fossil fuel diesel, it can reduce the carbon dioxide emissions by 4.536 kg, truly achieving green environmental protection and sustainable development." Tang Yougen gave the reporter an account.

In addition, aluminum used in carbon-free metal batteries is not only low-cost, but also has no toxic advantages. The metal power system keeps the power system running by directly replenishing or replacing metal fuel and electrolyte. Metal magnesium and aluminum have no negative impact on the environment, and the replaced oxidized metal fuel and electrolyte can realize the reduction regeneration cycle.
