Regarding the question of how much remaining battery is appropriate for recharging new energy pure electric vehicles, Hydrogen Cloud Chain's research on relevant vehicle models' reports indicates that the optimal charging range is between 20% and 90%. Charging within this range can minimize the impact on the power battery and effectively extend its service life. Power Battery: As is well known, the current domestic power batteries are mainly ternary lithium and lithium iron phosphate. Ternary lithium batteries are most afraid of overcharging and over-discharging. Overcharging can lead to fires, while over-discharging (complete depletion) can cause the entire battery to fail. Low Battery Warning: To prevent new energy vehicles from discharging completely, some manufacturers set a low battery warning at around 15%. Of course, the vehicle is not immobilized at this point and still has a certain driving range left. If you continue to drive, the vehicle's speed will be limited. Even if you press the accelerator pedal all the way down, the vehicle's speed can only be maintained at around 40 km/h.

I've been driving an electric vehicle for quite some time, and the timing of charging has a significant impact on the lifespan of a new car's battery. It's generally recommended to start charging when the battery level drops to between 20% and 30%, rather than waiting until it's almost empty to frantically look for a charging station. New car batteries are more delicate, and frequently waiting until the battery is low can lead to over-discharge and faster aging. I'm in the habit of using an app to set a reminder to charge when the battery reaches 25%, stopping at around 80%; for city commuting, charging twice a week is usually sufficient. Sticking to this routine long-term can save a lot of money on battery replacements. Whenever possible, opt for slow charging at home—it's gentler and safer than fast charging and can also make better use of the regenerative braking system to recover more energy, improving overall efficiency. Developing regular charging habits makes driving an electric vehicle both worry-free and cost-effective.

What do the PRNDS positions represent?

P stands for Parking gear, R represents Reverse gear, N denotes Neutral gear, D indicates Drive gear (forward), and S signifies Sport mode. Below is an introduction to the PRNDS gear positions: 1. P gear: Parking gear, used when parking your vehicle. The P gear automatically locks the engine, functioning similarly to a handbrake. Automatic transmission vehicles must be shifted to P gear to remove the key when turning off the engine, and some push-to-start vehicles also require shifting to P gear for ignition. 2. R gear: Reverse gear, engaged when reversing the vehicle. Typically, shifting to R gear automatically activates the reverse radar or rearview camera if equipped. 3. N gear: Neutral gear, used during brief stops or while waiting at traffic lights. However, the N gear lacks a locking mechanism, meaning the vehicle may still move under external forces such as inertia or on a slope. 4. D gear: Drive gear, the normal driving position for vehicle operation. 5. S gear: Sport mode ("S" is short for "sport"). In S gear sport mode, the transmission can shift freely but delays gear changes, maintaining higher engine RPMs for extended periods. This allows the car to operate at lower gears with higher RPMs, delivering greater torque output and acceleration.

What Causes the Steering Wheel to Make Abnormal Noises in Baojun Vehicles?

Below are the potential locations and reasons for abnormal noises when turning the steering wheel: 1. Turn signal reset sound: If the turn signal is activated while steering, the noise may originate from the rebound clip of the automatic reset mechanism for the turn signal. This requires confirmation by the vehicle owner. If confirmed, it is a normal occurrence. Sometimes, multiple clicks may be heard because the steering column has three automatic reset notches per full rotation. Turning the wheel one full rotation will produce three clicks. 2. Noise from the steering column dust cover: If the noise comes from below the steering wheel, it might be due to the steering column dust cover. Lack of lubrication in the dust cover can cause friction noises. Applying some grease inside the dust cover should eliminate the noise. 3. Noise from inside the steering wheel: If the noise comes from within the steering wheel, it is likely caused by the clock spring (spiral cable) for the airbag. Remove the steering wheel and apply grease to the clock spring. If the noise persists, replace the clock spring as it may be damaged. Handle the steering wheel gently during removal or disconnect the airbag fuse to prevent accidental deployment. 4. Noise from the strut mount bearing: If the noise comes from outside the vehicle, it might be due to insufficient lubrication in the strut mount bearing. Open the hood and listen for noises near the top of the strut mount. If confirmed, apply grease to the bearing. If the noise continues, replacement is necessary. 5. Noise from the stabilizer bar: If the noise is not from the strut, check the stabilizer bar bushings for looseness or damage. Loose or damaged bushings can cause noises not only when steering but also when driving over uneven surfaces. Loose bushings can be fixed by adding shims, while damaged ones must be replaced.

How to Test the Condition of Spark Plugs?

Spark plugs exhibit the following symptoms when they may be faulty: Difficulty in starting the car, both cold and hot starts are problematic, often requiring multiple attempts. Engine shaking, noticeable vibrations while driving the car. Lack of power, a significant decrease in performance compared to normal conditions. Increased fuel consumption. Stalling issues. Failed exhaust emissions tests. Common causes and diagnosis of spark plug failures: Several common issues can prevent spark plugs from functioning properly: Incorrect spark plug gap adjustment. A gap that is too small limits the contact area between the spark and the air-fuel mixture, and the flame kernel growth is suppressed by the electrode's flame quenching effect, resulting in weak sparks and difficult mixture ignition. Conversely, a gap that is too large may exceed the ignition system's voltage capacity, preventing spark generation. Cracked spark plug skirt. High-voltage current leaks through the crack, preventing sparks at the electrodes. Carbon buildup on electrodes, causing leakage from the center electrode to the surroundings instead of sparking to the side electrode. Excessive carbon deposits can short-circuit the spark plug, preventing sparks and damaging the insulator. Damaged electrodes. Prolonged electrical erosion from sparks or chemical corrosion from combustion gases can cause electrode breakage, preventing spark generation. Low insulation resistance of the spark plug. This reduces the ignition voltage applied to the spark gap, weakening or completely eliminating the spark. Short circuit in high-voltage wires. Leakage in the wire from the ignition coil to the distributor can prevent the entire engine from starting, while leakage in the wire from the distributor to a spark plug can prevent sparking in one cylinder. Burnt platinum contacts. This can prevent all spark plugs from firing, making the engine unable to start or run normally. Faulty spark plugs should be replaced promptly. The replacement steps are as follows: Open the engine hood, remove the plastic cover, and detach the high-voltage wires, marking each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one, ensuring the surrounding area is free of debris like leaves or dust. Insert the new spark plug into the hole, hand-tighten it first, then use the socket to secure it. Reattach the high-voltage wires in the correct firing order and replace the cover. Spark plug replacement interval: Typically, spark plugs should be replaced every 40,000 to 60,000 kilometers under normal maintenance conditions, but this may vary by brand and engine type. Always refer to the vehicle's manual for specific recommendations.
