How Much Difference Between Calculated and Actual Range of Electric Vehicles?

1 Answers

07/30/25 5:27am

Electric vehicle range calculation and actual difference are related to load weight, functional modules, ambient temperature, road conditions, speed, etc., making it difficult to calculate a specific value. Reasons for shortened electric vehicle range: 1. Motor issues: When motor efficiency decreases, the useless work increases, wasting power and reducing the range. 2. Tire pressure problems: At the same driving distance, low pressure increases the tire contact area, consuming more power, making it hard to move and reducing the range. 3. Controller issues: The controller is one of the core components. A faulty controller causes excessive starting current and prolonged starting time, wasting power and shortening the range. 4. Weather reasons: In winter, lower temperatures increase electrolyte viscosity, electrochemical reaction resistance, and reduce battery capacity, leading to decreased electric vehicle range.

Why Does the Engine Stall Easily When Starting in First Gear?

The reasons why the engine stalls easily when starting in first gear are: 1. Severe carbon deposits inside the engine cylinders; 2. Insufficient engine power; 3. Aging engine mounts; 4. Cylinder misfire. Precautions for starting the car include: 1. Do not look down at the mechanical parts; keep your eyes on the road ahead and both sides; 2. When starting downhill, release the brake first before pressing the accelerator and lifting the clutch; when starting uphill, release the brake when the engine sound becomes steady. The correct steps for starting are: 1. After pressing the clutch and starting the engine, press the clutch pedal all the way down with your left foot to fully disengage the clutch; 2. Shift the transmission into first gear; 3. Release the handbrake and accelerate.

What is the engine speed when starting the car?

The engine speed when starting the car is 1200 to 1500 revolutions per minute (RPM). RPM refers to the number of revolutions the engine crankshaft makes per minute. The engine speed affects the number of work cycles per unit time or the effective power output of the engine. Its function is to promptly reflect the operating condition of the engine, allowing the driver to better coordinate the transmission gear and throttle position, ensuring the car maintains optimal working conditions. Precautions when starting the car include: 1. Do not start the engine immediately after inserting the key; 2. For vehicles with a one-button start, do not press the brake pedal first when starting; 3. If the key fob for a one-button start vehicle is out of battery, bring the key close to the start button; 4. Do not use excessive force if the key cannot be turned after insertion.

How to Remove Stickers from a Car?

Methods to remove stickers from a car include: 1. Use a specialized adhesive remover; 2. Apply essential oil, alcohol, or diesel on the sticker and wipe it off with a towel; 3. Clean with soapy water; 4. Use a hot towel or hair dryer to heat the sticker for easy peeling; 5. Gently scrape off with a soft paper cutter blade. The functions of car stickers are: 1. Beautify the car body and highlight its contour lines; 2. Remind other vehicles to maintain a safe distance to prevent accidents; 3. Protect the paint from natural erosion and avoid damage from scratches; 4. Cover scratches; 5. Reflect light to attract other drivers' attention and improve driving safety.

How to Reverse Park an Automatic Transmission Car?

Steps for reversing an automatic transmission car into a parking space are: 1. Press the foot brake firmly and shift from N (Neutral) to R (Reverse); 2. Release the handbrake and check the intended reversing path through the rearview mirror; 3. Lift the foot brake while keeping ready to press it again to stop the car; 4. Once reaching the designated position, press the foot brake fully; 5. Engage the handbrake and then release the foot brake; 6. Press the foot brake and shift from R to N; 7. Release the foot brake to complete the reversing process. Automatic transmission eliminates the need for manual gear shifting by the driver, as the vehicle automatically selects the appropriate gear based on speed and traffic conditions. Precautions for reversing with an automatic transmission include: 1. Do not leave children unattended outside the car during reversing; 2. Keep the right foot on the brake when not using the accelerator; 3. Observe rear obstacles in advance.

What is the normal tire pressure for car tires?

Car tires have a normal tire pressure between 2.3 to 2.5 bar. Tire pressure refers to the air pressure inside the tire. The effects of low tire pressure are: 1. It increases the contact area between the tire and the ground, making the tire prone to overheating; 2. It causes the tire body to expand, leading to cracks on the inner and outer sides of the tire; 3. It accelerates rubber aging and increases tire wear. The effects of high tire pressure are: 1. High tire pressure increases friction between the tire and the ground, reducing tire grip; 2. It affects the car's braking performance and driving comfort; 3. It accelerates wear on the central tread of the tire, reducing its lifespan.
