What can Silicon Carbide Devices Bring to New Energy Vehicles?

The European Commission has submitted to member states a new draft of sanctions against Russia, including an oil embargo. Some member states that rely heavily on Russian energy sought exemptions.  

Western media reported that the European Commission draft of the sixth round of sanctions against Russia includes within six to eight months gradually banning oil imports from Russia, but allowing Hungary and Slovakia to extend the transition period for several months; The Russian Savings bank and other large financial institutions on the sanctions list.  

The European Union has imported 44 billion euros of fossil fuels from Russia since Russia launched its special military operation against Ukraine in late February, according to Finland's Energy and Clean Air Research Center.  

The Institute for European and Global Economics in Brussels estimates that the European Union currently consumes about $450 million worth of Russian oil a day.  

Among EU members, landlocked Hungary and Slovakia, which import most of their oil from Russia, cannot quickly find alternative supplies.  Slovakia says the transition will take years.  Some officials believe Bulgaria and the Czech Republic may also seek to opt out of oil sanctions against Russia.

Affected by the ever-changing international situation, the supply and prices of international bulk silicon carbide powder are still very uncertain.

What is Silicon Carbide SiC?
Silicon carbide (SiC) is a hard compound containing silicon and carbon. A semiconductor, it is found in nature in the form of the extremely rare mineral moxanite. 
It has been mass-produced in powder and crystal form since 1893 for use as an abrasive.  Silicon carbide particles can be sintered together to form very hard ceramics that are widely used in applications requiring high durability, such as ceramic plates in car brakes, car clutches, and bulletproof vests. Large silicon carbide single crystals can be grown by the Lely method, and they can be cut into gemstones called synthetic mossanes. 
 
What can Silicon Carbide Devices Bring to New Energy Vehicles?
Silicon carbide power devices have been used in critical power systems inside electric vehicles, including traction inverters, on-board chargers (OBC), and DC-DC converters.  Key advantages over traditional silicon devices include higher voltage and higher frequency features, resulting in higher system efficiency, faster switching, lower losses, and better thermal management. Compared with silicon-based devices, silicon carbide devices have the following advantages:
 
Lift acceleration 
The use of silicon carbide devices can make the driving motor bear more input power at low speed, and because of its high thermal performance, not afraid of the thermal effect and power loss caused by excessive current. When the vehicle starts, the driving motor can output more torque and obtain stronger acceleration ability. 
 
Increase mileage 
SiC devices can reduce the loss through two dimensions of conduction/switching, so as to achieve the purpose of increasing the range of electric vehicles. The results show that the turn-off loss of sic-MOS is about 20% of that of Si-IGBT at 25°C junction temperature. At 175°C junction temperature, the turn-off loss of sic-MOS is only 10% of that of SI-IGBT.  In general, the use of SiC devices in new energy vehicles can increase the driving range by 5-10%, and the average driving range is more than 600 kilometers. 
 
High rated voltage 
Silicon carbide MOSFET has a higher voltage rating, making the technology suitable for EV applications and EV quick charging infrastructure. More importantly, the SiC can be replaced directly without major changes, enabling rapid development while keeping the BOM low. 
 
Lightweight 
To achieve lightweight thanks to the superior performance of SiC, SiC devices can achieve the effect of reducing the volume in the following aspects: 
1, the package size is smaller, and the average weight is reduced by 150 to 200 kg; 
2, reduce the use of filters and passive devices such as transformers, capacitors, inductors, etc.; 
3, reduce the radiator volume. 
 
Economical
At present, the price of SiC devices is 4-6 times that of silicon based devices, but the use of SiC devices to achieve a substantial reduction in battery cost and the improvement of the range, reducing the overall cost of the vehicle.
 
Silicon Carbide Price
The price is influenced by many factors including the supply and demand in the market, industry trends, economic activity, market sentiment, and unexpected events.

The report by the Finland-based Center for Energy and Clean Air comes as Ukraine urges the West to cut off all trade with Russia to stop funding the Kremlin's war chest.

The European Union recently decided to impose a gradual embargo on Russian oil imports, with some exceptions, according to reports. Russian gas, on which it relies heavily, is currently unaffected.

In the first 100 days of the Conflict between Russia and Ukraine (February 24 to June 3), the EU accounted for 61 percent of fossil energy imports, or about 57 billion euros, according to the Energy and Clean Air Research Center.

Russia's revenue came first from crude oil sales (43.87 billion euros), followed by pipeline gas (22.89 billion euros), then petroleum silicon carbide powder, please feel free to contact us and send an inquiry.
