Who Are Tesla's Main Suppliers?

Tesla is secretive about suppliers but here's what we know

A relative newcomer to the automotive sector, Tesla, Inc. (Nasdaq: TSLA), has made a name for itself in the electric vehicle (EV) world. Headquartered in California, this electric vehicle manufacturer and energy storage company is quickly becoming a household brand. Tesla initially received a lot of attention when it produced the first electric sports car, the Roadster. This was followed by the Luxury Model S. Both were boosted by Tesla's charismatic CEO, Elon Musk.

The Roadster was the first electric car to use lithium-ion batteries. It was also the first to have a cruising range of over 200 miles. The limited cruising range between charges has been one of the major criticisms of electric cars. Most gasoline-powered vehicles have a cruising range of around 350 miles.

Concerned about competitors either obtaining inside information or buying out necessary parts, Tesla is secretive about its many suppliers. Nonetheless, some have been uncovered by diligent researchers. Tesla manufactures the basic electric components of the car, including the electric motor, the battery pack, and the charger. It also aims to make its own batteries and microchips. Essential components that it needs come from Tesla suppliers spread across the U.S., Europe, and Asia.

Key Takeaways

  • Tesla Motors has become known for producing well-designed and innovative electric vehicles.
  • To assemble its cars, Tesla sources parts from a range of Tesla suppliers.
  • Some suppliers provide ordinary car parts, others provide electric vehicle parts. Still, others provide steel, industrial products, and minerals.
  • The transition to EVs is moving at a rapid pace and EV suppliers have room to grow.
  • As the EV market develops, Tesla suppliers may offer worthwhile investment opportunities.

Are Supplier Stocks a Better Way to Invest?

Investors watching the EV market might do well to consider EV suppliers as well as EV makers. Major car companies continue to confirm their commitment to producing EVs. That bodes well for providers of EV components and the potential investor benefits:

  • Diversification: Manage risk by spreading investments among various suppliers and makers in the EV sector.
  • Value: If an EV maker is overvalued, Tesla suppliers' stocks may offer a smart investment alternative.
  • Performance: The continued transition to EVs plus favorable government regulations and incentives can mean increased consumer demand, more EVs produced, and growth in the need for EV suppliers' products.

While supplier competition will likely intensify given the opportunities in the EV market, there's also the potential for stars to emerge and reward investors.

Who Is Tesla's Biggest Supplier?

Some of Tesla's suppliers with substantial market capitalizations include Emerson Electric, Garmin Ltd., Danaher Corporation, and Nucor Corp.

Who Are Tesla's Battery Suppliers?

Tesla has plans to make its own batteries. A large supplier of the lithium required for these batteries is China's Ganfeng Lithium Co. Ltd. Australian mining company BHP supplies needed nickel. Anglo-Swiss company Glencore provides cobalt. All three are Tesla suppliers.

Does Tesla Make Its Own Microchips?

Yes, it does. To reduce its dependence on chipmakers, avoid order bottlenecks, and improve energy efficiency, Tesla has pursued the manufacture of its own semi-conductors made from silicon carbide. Silicon carbide is more durable and energy-efficient than the standard, mass-produced silicon wafer.
