德国博世：300毫米晶圆厂，10亿欧元投资：SiC器件生产
独ボッシュ：
既存の工場ﾃﾞ､SiCデバイスを生産します。
EVの走行距離を､SiCパワー半導体を採用することで、従来比6％増加できると見ている。
日産自動車：「リーフ」の例
バッテリー容量62kWhのモデルの走行距離がWLTCモードで458kmです。
SiCパワー半導体の採用で､走行距離が485kmに伸びる計算です。
SiCパワー半導体：
- 熱損失を抑え、動作可能な温度の引き上げで、冷却機構コストを削減。
- また､バッテリーの容量を縮小することも可能。
EVのコストの大部分を占めるバッテリーのコスト低減が図れ、車両価格を抑えることにつながる。

Bosch ：Claims Better Chips Can Increase EV Range
Now Bosch
has announced it is building a factory in Dresden, where it will use 300 millimeter silicon carbide disks to make a new kind of semiconductor.
What’s the big deal?
Using larger discs
drives down the cost of manufacture and the new chips transmit electricity about 6% more efficiently than conventional chips.
Greater efficiency
has several benefits for electric cars. It means a car can travel about 6% further on a single charge.
That can make consumers happy — 6% more range means 265 miles for a car currently rated at 250 miles —
or it can allow companies to decrease the size of the batteries they need to get the range their cars need to be competitive.
Smaller batteries also cost less, which means companies can lower the selling price of their electric cars to boost sales.
Greater efficiency means less electricity is lost to heat during charging and driving.
Less heat means smaller cooling systems, which can also save manufacturers money.
According to SlashGear, the new silicon carbide semiconductor design
has better electrical conductivity than existing chips, thanks to more carbon atoms being packed in during the manufacturing process.
That means
the electronics can achieve higher switching frequencies while also losing less power in the form of heat.
