The reason for the limited functionality of the BYD Qin DMI EV is damage to the vehicle's high-voltage system. Below are the relevant details: 1. Battery Management System Module Malfunction: A malfunction in the battery management system module can restrict the battery power output, causing the dashboard to display an EV function limitation alert. A technician will use a specialized automotive diagnostic computer to read the battery management system module data and determine if it is faulty. 2. Drive Motor Malfunction: A malfunction in the drive motor can trigger a system fault, leading to an EV function limitation alert on the dashboard. A technician will use a specialized automotive diagnostic computer to read the drive motor data and analyze it to determine if the motor is faulty. 3. Battery Overheat Protection: If the driver frequently accelerates abruptly while driving, it can cause the battery to overheat and enter a protection mode, limiting power output and resulting in an EV function limitation alert on the dashboard.

What is the Difference Between 4AT and 6AT Transmissions?

4AT and 6AT transmissions differ in the number of gears: a 4AT transmission has 4 forward gears, while a 6AT transmission has 6 forward gears. Transmissions are divided into manual transmissions and automatic transmissions. Manual transmissions consist of gears and shafts, achieving speed and torque changes through different gear combinations. Automatic transmissions are composed of a torque converter, planetary gears, and a hydraulic control system, achieving speed and torque changes through hydraulic power transmission and gear combinations. The functions of a transmission are: 1. To change the transmission ratio and expand the range of torque and speed variations of the driving wheels; 2. To enable the vehicle to reverse while maintaining the engine's rotation direction; 3. To use neutral gear to interrupt power transmission, allowing the engine to start, idle, and facilitating gear shifts or power output.
