Tesla’s chassis protection mainly includes aluminum deflectors used to push away foreign objects and titanium shields to protect the battery from foreign objects. The fatal weakness of the Tesla Model 3 chassis design is the front and rear There was no protection left or right. The battery and other parts are on the same level. The ground clearance of the chassis itself is only 13 centimeters, which is relatively low. There is no protection around it. As a result, if any foreign matter enters the vehicle while driving, it can directly hit the battery at the bottom, greatly damaging the battery. Increases the possibility of battery damage and combustion.
Features of Tesla Model 3
The powertrain structure of Tesla Model 3 is to install a motor on one side of the reducer and an inverter on the other side. The structure of the Model s remains the same, but the inside of the motor is completely different. It is worth noting that Model 3 uses "embedded permanent magnet synchronous motor (IPMSH-interior permanent magnet synchronous motor)" and "oil cooling".
Tesla’s Roadster, Model S, and Model X all use induction motors, but Model 3 uses an embedded permanent magnet synchronous motor for the first time. The size of the permanent magnet synchronous motor has more advantages. The permanent magnet synchronous motor focuses on efficiency in the small and low-medium speed fields, while the induction motor focuses on efficiency and large torque in the high-speed field.
