Is NIO et7 a heat pump air conditioner?

Nio et7 is not a heat pump air conditioner.

In order to reduce blind spots and improve forward visual redundancy, ET7 uses a "watchtower"-style lidar/camera, so its roof will have three eye-catching "little corners". It can be regarded as its "postcard".

The screen, shift paddles and other components of Weilai ET7 all continue the family-style design, but the control lines and air-conditioning outlets have been simplified. The benefit brought by this simplification is visual On the road, the entire vehicle has a stronger sense of technology and future.

The highlights of NIO ET7 are also the smart cockpit based on the third-generation Qualcomm Snapdragon digital cockpit platform; the standard NAD NIO autonomous driving platform that is "stacked" with sensors and computing hardware; by the end of 2022 It can provide a 150kWh solid-state battery with a comprehensive cruising range of more than 1,000km.

Recently, Weilai officials learned that the C sample of the first 180kW silicon carbide electric drive system of Weilai ET7 was officially rolled off the assembly line at the Nanjing Advanced Manufacturing Technology Center.

This means that the silicon carbide electric drive products equipped with NIO ET7 have completed the development and engineering verification of all key technologies. The molds and production lines have fully completed pre-mass production preparations and have entered the stage of verifying the production process. and PV production verification stage of the process, and gradually optimized to mass production status.

Silicon carbide technology is mainly used in the core power electronic devices of the ET7 permanent magnet motor controller. The function of this component is to convert the DC power from the battery into the AC power required by the motor.

After using silicon carbide (SiC) power modules, they are more resistant to high temperatures than traditional silicon-based modules (IGBT), and the maximum current capacity is increased by more than 30% in the same volume.

In addition, this module has a wider voltage range, better expansion compatibility and faster switching speed, which can greatly reduce the overall loss and effectively increase the battery life by about 4-6.

ET7 is equipped with a 180kW front permanent magnet synchronous motor with a maximum torque of 350Nm, an efficiency of up to 97.2, and a controller power density that exceeds 36kW/L.

ET7 is the first model in the NIO product family to adopt the second-generation high-efficiency electric drive platform. The dual-motor system consisting of a 180kW front permanent magnet synchronous motor and a 300kW rear induction asynchronous motor has a 0-100km acceleration capability of 3.9 seconds.

With a 150kWh solid-state battery, it can achieve a cruising range of 1,000km, taking into account high performance and long-lasting performance.
