lithium-ion cell的八卦，Yahoo名人娛樂都在討論

VINFAST BẮT TAY VỚI STOREDOT (ISRAEL) - CÔNG TY SỞ HỮU CÔNG NGHỆ SẠC PIN CHỈ TRONG 5 PHÚT ĐƯỢC 80%

Ngoài thỏa thuận ghi nhớ với Gotion High-Tech (Trung Quốc) trong kế hoạch cung ứng pin Lithium-ion (LFP) cho ôtô điện, nhằm xây dựng nhà máy sản xuất cell pin đầu tiên tại Việt Nam. VinFast cho biết đang đàm phán với hai đối tác khác về pin thể rắn (SSB) và pin lithium-ion mới với khả năng sạc đầy 80% trong 4-5 phút, nhờ sử dụng các hạt nano bán dẫn thay cho graphite (than chì) 😮

Bên cạnh công nghệ pin mới, để đạt tốc độ sạc 5 phút, StoreDot cho biết cần những trạm sạc với công suất lớn hơn thông thường. Nếu sử dụng cơ sở hạ tầng trạm sạc sẵn có như hiện nay, StoreDot đặt mục tiêu mỗi lần sạc pin trong 5 phút sẽ cấp đủ điện cho quãng đường 161 km.

Kể ra cũng kinh thật anh em à. Sau này mà sử dụng xe điện của Vin sạc có 5 phút mà đi được tận 161 km thì cũng đáng để trải nghiệm đấy (tính ra còn nhanh hơn cả sạc điện thoại) 😅

The BMW Group continues to expand its electro-mobility activities. In conjunction with its partner, Brilliance China Automotive Holdings Ltd., the BMW Group opened a new “High-Voltage Battery Centre” in Shenyang, China today. The battery factory will supply the nearby Dadong plant, which is operated by the BMW Brilliance Automotive (BBA) joint venture and will produce the BMW 5 Series Plug-in Hybrid for the local market.

Oliver Zipse, member of the Board of Management of BMW AG, responsible for Production: “The innovative High-Voltage Battery Centre in Shenyang is an important step in the BMW Group’s electro-mobility strategy. It is the first battery factory of any premium automotive manufacturer in China and already the third in our production network, after Germany and the US.”

The BMW Group is integrating its battery factories into the existing international production network. Oliver Zipse: “By 2025, we expect our electrified BMW and MINI models to account for between 15 and 25 per cent of global sales. This adds up to several hundred thousand vehicles per year. It therefore makes sense for us to integrate electro-mobility into the existing production system.” Doing so will enable the BMW Group to respond flexibly to demand for electrified models.

Competitive edge through in-house know-how

Alongside the electric motor, the high-voltage battery is a central element of partially and fully-electrified vehicles. In-house production gives the BMW Group a decisive competitive advantage by securing know-how in new technologies, gaining key systems expertise and leveraging cost benefits. The company already produces electrified vehicles at ten locations worldwide. The high-voltage batteries needed for these models come from the BMW Group plants in Dingolfing, Spartanburg and now also Shenyang. The Dingolfing plant will play a leading role within the network as the centre of competence for electric drive systems.

From cell to high-voltage battery

Production of high-voltage batteries is divided into two production stages. First, in a highly-automated process, supplied lithium-ion cells, which are about the size of a paperback book, are checked and then combined into a larger unit, the so-called battery module.

The battery modules are then mounted together with the connections, control units and cooling units in an aluminium housing. The size and shape of the aluminium housing, as well as the number of battery modules used, depends on the vehicle variant. In this way, a perfectly adapted "battery pack" or high-voltage battery is created.

This combination of standardised battery modules and housings flexibly adapted to the vehicle has several advantages: It ensures uniform properties and quality standards in the production of high-voltage batteries. The modular design of the high-voltage batteries also forms the basis for a wide variety of electric drive variants. Last but not least, this modular concept is a requirement for responding quickly to customer demand and leveraging cost benefits.
