What does RD mean on an electric car?

Electric vehicle's RD button is the parking safety lock. Below is relevant information about electric vehicles: 1. Introduction: Electric vehicles (BEV) refer to vehicles that use onboard power sources as their energy, employ electric motors to drive the wheels, and comply with all road traffic and safety regulations. 2. Types: There are mainly three categories of electric vehicles: pure electric vehicles, hybrid electric vehicles, and fuel cell electric vehicles. 3. Power source: Provides electrical energy to the drive motor of electric vehicles, and the motor converts the electrical energy from the power source into mechanical energy. The most widely used power source is lead-acid batteries, but with the advancement of electric vehicle technology, lead-acid batteries are gradually being replaced by other types of batteries due to their low energy density, slow charging speed, and short lifespan.
I just started driving an electric car not long ago. Every time I see 'rd' on the dashboard, I guess it probably stands for 'Range Display', which shows how many kilometers the car can still run. This is crucial as it indicates the remaining driving range. When I'm driving, especially before long trips, I always take a glance at it for peace of mind. The range is affected by many factors. For example, when the weather gets cold, battery efficiency drops, and that number plummets rapidly. Using air conditioning or driving fast also consumes a lot of power. I've also noticed that insufficient tire pressure can shorten the range, so it's important to develop a habit of regular checks. To optimize, I try to maintain steady driving and avoid sudden acceleration to squeeze out a bit more mileage. Overall, it's been a great help, but I also need to pay attention to its fluctuations to ensure I don't run out of power and get stranded midway.
