Volkswagen announced future battery methods: cost will drop 66%

Comprehensive foreign report, the Volkswagen Group will disclose the battery selection method of pure electric vehicles within two months, which is expected to use a single lithium-ion battery unit to cut battery costs of two-thirds. On the energy density, the new battery is expected to reach the current 5 times level. Volkswagen's new battery strategy wants to go out to the Volkswagen Group, announced that the battery selection method of pure electric cars will be announced before July 2015.

Current focus is important to get an existing lithium-ion battery upgrade version solution, as well as two directions of novel solid state battery technology. At the same time, Heinz-Jakobneusser, the board member of the Volkswagen Group, is also revealed to the media recently, and the company's future electrified vehicle may turn to a single lithium-ion battery unit design. Although the battery car model is different, the unified battery unit can use different packages and methods to meet various needs.

The Group's goal is to reduce battery cost 66% by simplifying battery cell design. Nosa said in a round table: "We clearly realize that the Group should use the battery unit, which means each product in the group, each brand uses the same battery unit, otherwise we cannot achieve cooperation during the development process. effect.

"At the moment, the public vehicle adopted a variety of lithium-ion battery units. For example, Panasonic is E-golf, golf GTE plug-in hybrid car, Audi A3 electric car supply battery, Samsung is Passat GTE, Audi other electric car supply battery. A spokesperson said that a single battery design makes it possible to assemble factory production in Braunschweig's battery modules in Braunschweig, Germany, and even use unified battery cell designs by different battery suppliers.

But Nos did not give the specific route switching time node. Is the energy density increased by 4 times? Since the battery is far from the energy density, it is one of the electric vehicles for a long time. Among the new regulations issued by many countries, only the electric vehicle single charging life will reach a certain level, and can enjoy subsidy preferential policies.

For example, in the United States, EPA, EPA, EPA, E-golf, pure electric vehicle, the average life-saving mileage should reach 83 miles (about 133 km), and the mass battery has been tested. To this end, the mass and other manufacturers have made a breakthrough in improving battery energy density. It is reported that the public is developing the next-generation lithium-ion battery unit technology, and the energy density can reach 5 times the current battery.

This will make the battery pack of the Volkswagen electric car, and the endless mileage is larger. However, the public does not explain in detail what structure is achieved. Some views guess the future will turn to the solid state battery (not confirmed whether the solid-state lithium-ion battery).

In the third quarter of 2014, Volkswagen once expressed its optimistic battery prospects, and founded to develop solid-state battery entrepreneurial companies Quantumscape, and 5%. Solid batteries have advantages over traditional lithium-ion batteries in storage capacity, and there are also advantages such as strong flame retardancy. Safety performance is stronger.

Volkswagen CEO Martin Wen Den said last November: "I think that the application of solid battery technology is huge, and it is very likely to increase the electric vehicle life mileage to 700 kilometers. ".
