How many kilometers can a 72V 20Ah lithium battery run?

About fifty to sixty kilometers. For a 72V 20Ah battery, a 1000W motor consumes power too quickly, which means it can run fast but not far. Of course, this is under full-speed conditions. If the throttle is only slightly turned to maintain a speed of 20-30 km/h and moves at a constant speed, it can still run quite far, with seventy to eighty kilometers being quite normal. Additional content: Lithium battery maintenance methods: 1. Do not replace the charger arbitrarily: Do not change the charger at will or remove the speed limiter on the controller. 2. Protect the charger: To reduce costs, most current chargers are not designed for high shock resistance. Generally, chargers should not be placed in the trunk or on the frame of the electric vehicle. In special cases where movement is necessary, the charger should be packed in foam plastic to avoid shock and vibration. 3. Charge in time: Sulfation begins after the battery is discharged, with significant sulfation occurring within 12 hours. Timely charging can eliminate minor sulfation. If not charged in time, these sulfation crystals will gradually accumulate and form coarse crystals. Ordinary chargers are ineffective against these coarse crystals, leading to a gradual decrease in battery capacity and shortened battery lifespan.

How to Use the Car Tire Pressure Monitoring System?

Press and hold the setting button on the display for about 3 seconds until you hear a click, and the left front wheel will flash; at this time, bring the display close to the sensor, and the display will automatically receive the sensor's ID. After the display shows the identification, click OK to confirm; then press SET to proceed to other tires, approach the other sensors one by one, and debug them sequentially. Tire Pressure Monitoring: Tire pressure monitoring is the real-time automatic monitoring of tire pressure during car driving, and it alerts for tire leaks and low pressure to ensure driving safety. Direct Tire Pressure Monitoring: The direct tire pressure monitoring device uses pressure sensors installed in each tire to directly measure the tire pressure. It uses a wireless transmitter to send the pressure information from inside the tire to a central receiver module, which then displays the tire pressure data for each tire. When the tire pressure is too low or there is a leak, the system will automatically alert. Indirect Tire Pressure Monitoring: When the pressure of a tire decreases, the weight of the vehicle will cause the rolling radius of that wheel to become smaller, making it rotate faster than the other wheels. By comparing the rotational speed differences between the tires, the system monitors the tire pressure. The indirect tire pressure alert system actually relies on calculating the rolling radius of the tires to monitor the pressure. Introduction to the Tire Pressure Monitoring System (TPMS): It combines the advantages of the two systems mentioned above, equipping direct sensors in two diagonally opposite tires and a 4-wheel indirect system. Compared to using a full direct system, this composite system can reduce costs and overcome the defect of the indirect system not being able to detect when multiple tires have low pressure simultaneously. However, it still cannot provide real-time data of the actual pressure in all four tires like the direct system does.

How to Fully Lower the Rear Window of a Passat?

Press the button to the first position and release it when the desired position is reached. Briefly press the switch to the second position to automatically open the window. Push the button upward to the first position and release it when the desired position is reached. Pull the button forcefully to the second position, and the window glass will automatically rise and close. Simply hold the unlock button on the key for about 3 seconds, and all four window glasses will synchronously lower.

How to Legally Install a Tow Hook?

First, locate the position as indicated in the vehicle's user manual, which is typically covered by a round or square cap. Press repeatedly around the edges of the tow hook cover to find an angle to pry it open. Use a small stick with a diameter smaller than the tow hook cover, wrap it with a cloth, and gently poke around to open it. After connecting the tow hook, you also need to connect the electrical circuit. Once the towing vehicle and the towed vehicle are connected via the tow hook, attach the safety wire to the steel ring next to the tow hook.

How to Use Turn Signals in a Manual Transmission Car?

When starting the vehicle, turn on the left turn signal. When parallel parking, turn on the right turn signal. At intersections and forks, turn on the left turn signal when turning left, and the right turn signal when turning right. When changing lanes to the left, turn on the left turn signal. When entering a roundabout, no turn signal is needed; when exiting a roundabout, turn on the right turn signal. When overtaking, first turn on the left turn signal, and after maintaining a necessary safe distance from the overtaken vehicle, turn on the right turn signal.

How to drive when one side of the double yellow line is solid and the other is dashed?

Lane changes are allowed with dashed lines. Only the side with the dashed line can cross into the lane with the solid line, and the lane change must be completed within the dashed section. There is another type of line called longitudinal deceleration lines, which are commonly seen on overpasses, toll stations, and other places. Longitudinal deceleration lines also consist of one dashed and one solid line.

How to Inspect a Repaired Accident Vehicle?

Request a written checklist and confirm the repair timeline with the repair shop. When picking up the vehicle, verify each item on the list to ensure the repairs were completed correctly. A clean exterior helps the owner spot issues during inspection. A reputable repair shop must deliver the vehicle in a spotless condition. More detailed and professional inspections are essential. This is the key focus when accepting a repaired accident vehicle—checking whether the repaired areas truly meet expectations. For some accident vehicle repairs, issues may only become apparent months later.
