Tesla Model 3 teardown

  Tesla surpassed Jaguar in the global sales of luxury vehicles in 2018, coming in ninth. This report introduces the features of the electric components that were revealed in Munro's teardown survey of the Model 3, which is Tesla’s best-selling model.

  According to a Nihon Keizai Shimbun (Japan Economics Newspaper) article dated February 19, 2019, the global sales volumes of the 12 luxury car brands (e.g., Mercedes-Benz, BMW, Lexus) reached a record high of 9.48 million units, up 2% y/y. The highest increase was at Tesla, whose sales increased 2.4 times y/y to 245,000 units. Of the total 220,000 unit increase for the 12 brands, 140,000 units were for the best-selling EV in the world, the Tesla Model 3.

  Tesla received orders for over 300,000 units of its affordable flagship EV compact sedan, the Tesla Model 3, which was announced in 2016 and started to be delivered from 2018. Tesla managed to hit its target of producing 5,000 Model 3 vehicles at the end of June 2018, achieving stable production volumes from the third quarter of 2018. Sales volumes of the Tesla 3 model was 1,770 units in 2017, increasing to 145,610 units in 2018.

  The motor used for the Model 3 has been changed from that of the conventional AC induction motors used in all Tesla products to date to an interior permanent magnet synchronous motor (IPMSM), and the cooling method has been changed from that of a water cooled system to an oil cooled system, resulting in an electric powertrain that is smaller and highly efficient. The inverter has been made smaller by adopting a new power module that is probably made of SiC (silicon carbide) steel material. For the battery, a new cell configuration has been adopted, and the battery is characterized by a number of unique connection methods and technical features to make it a highly reliable battery with a high capacity.
