Why Does a New Energy Vehicle Lose Power After Sitting for a Few Days?

New energy vehicles lose power after sitting for a few days due to their inherent characteristics. Generally, when the battery is not in use, it will experience slow discharge. Below are some usage tips for new energy vehicles: Regularly Check the Battery: New energy vehicles require regular battery inspections to prevent the battery from remaining in a low-power state for extended periods. If the vehicle is not in use for a long time, the battery should be fully charged before storage, and its power level should be checked monthly to ensure timely recharging. During daily use, avoid waiting until the battery is completely depleted before recharging. Avoid Sudden Acceleration While Driving: When driving a new energy vehicle, avoid sudden acceleration, as pressing the accelerator pedal hard can generate a large instantaneous current, causing the lithium battery to discharge rapidly. Based on the performance of the lithium iron phosphate batteries currently used in new energy vehicles, high-current pulse discharge can significantly shorten the battery's lifespan.

I've encountered similar situations with my new energy vehicle, usually due to the background system consuming power. Even when parked, the GPS positioning and remote control modules remain operational, drawing power to maintain network connectivity. The battery management system also works to balance the cells, ensuring safety, which consumes a significant amount of power. In high or low temperature environments, the thermal management system automatically activates to protect the main battery, adding extra power consumption. It's advisable to regularly monitor the battery status via the mobile app. If the small battery is found to be old, replace it promptly to avoid exacerbating the issue. Choosing a shaded and cool spot for parking can help save power.

Does the Radiator Condenser Need Cleaning?

The radiator condenser needs cleaning. Reasons are as follows: 1. Cooling: The principle of the car condenser is similar to that of a household air conditioner, with its main function being cooling. 2. Removing debris: The condenser is usually located at the front of the car, where dust, willow catkins, leaves, and small insects can adhere to it, leading to poor heat dissipation, reduced cooling performance of the condenser, resulting in the air conditioner not cooling properly, and even causing the engine water temperature to rise. 3. Affecting refrigeration: If not cleaned in time, it can affect the vehicle's cooling effect, increase engine load, and lead to increased fuel consumption, accelerated wear, and increased noise.

What causes the BMW BSD bus communication failure?

BMW BSD bus communication failure is mainly caused by low voltage, requiring inspection of the generator, current sensor, water pump, engine, and oil hydraulic sensor. Below is relevant information about BMW BSD: 1. Concept of automotive BSD: Automotive BSD refers to the Blind Spot Detection system. 2. Concept of the blind spot system: The blind spot detection system uses digital infrared cameras installed in the car's door mirrors to monitor traffic conditions on both sides of the vehicle. While driving, the system allows the driver to proceed without worry by monitoring the surroundings. When a car approaches or is in the blind spot, the blind spot monitoring system alerts the driver through sound and light signals. 3. Enhancing safety capabilities: The blind spot monitoring system can improve the vehicle's safety by reducing the likelihood of collision accidents during lane changes. Collisions often occur during lane changes because the car's rearview mirrors have blind spots. When another vehicle is in the blind spot, it cannot be seen through the rearview mirror, increasing the risk of an accident if the car changes lanes. 4. Preventing accidents: The blind spot monitoring system is particularly useful during lane changes, reversing out of parking spaces, driving in rain or fog when rearview mirrors are unclear, and when driving at night with headlights from behind causing glare. Especially during rainy days and nighttime driving when rearview mirror visibility is poor, the system significantly helps in preventing potential accidents.

What is the trick to never stalling when starting on a slope?

The trick to never stalling when starting on a slope is: 1. After engaging first gear, first apply throttle by pressing the accelerator until the tachometer reads 1500 to 2000 RPM, then keep your right foot steady; 2. Slowly release the clutch to the semi-engagement point, then press it back slightly—just before reaching the actual semi-engagement point—and keep your left foot steady while quickly releasing the handbrake; 3. As you release the handbrake, if you notice the car starting to roll backward, gently release the clutch with your left foot while maintaining the throttle at 1500 to 2000 RPM. Key points to remember when starting on a slope: Do not lift the clutch while pressing the accelerator, and lift the clutch slowly—doing it too quickly can cause the engine to stall.

What is the warranty period for a repaired accident vehicle?

Different types of vehicles and varying degrees of repairs will result in different warranty periods. For passenger vehicles, the quality assurance period for complete vehicle repairs or assembly repairs is 20,000 kilometers or 120 days. For secondary maintenance, the quality assurance period is 6,000 kilometers or 35 days. For primary maintenance, minor repairs, and parts repairs, the quality assurance period is 2,000 kilometers or 10 days. Below is additional information: 1. Accident vehicle: Refers to a vehicle that has been damaged due to non-natural wear and tear, resulting in decreased mechanical performance and economic value. Accident vehicles generally refer to vehicles with structural damage. Flood-damaged cars and fire-damaged cars also fall under the category of 'special accident vehicles.' 2. Methods to identify an accident vehicle: Exterior inspection, light inspection, insurance record check, and interior inspection.

Where to Check the Production Date of Tires?

The production date of tires can be found on the outer sidewall of the tire. It is a series of alphanumeric characters starting with "DOT," which stands for the certification by the U.S. Department of Transportation. The following numbers and letters represent the tire's origin information and factory code, while the last four digits indicate the production date. In addition to the production date, the tire sidewall also displays the tire width, aspect ratio, tire type, rim diameter, load index, and speed rating. Tires typically have a shelf life of 4 to 5 years. When purchasing, pay attention to the production date and try to avoid tires that have been stored for more than 3 years. Since tires are made of rubber, they can deteriorate over time, leading to reduced performance. If cracks appear, there is a higher risk of tire blowouts, which can compromise driving safety.
