What happens if you don't unplug a new energy vehicle after it's fully charged?

New energy vehicle charging piles do not have power-off protection function. After the battery is fully charged, it will continue to charge, and prolonged charging can damage the battery. The following are specific hazards: Battery aging: Although electric vehicles now have safety measures in place for charging, you still need to be careful when charging them. Forgetting to unplug the power after the electric vehicle is fully charged will cause battery aging. Moreover, if the power is not unplugged for a long time, the battery's internal components will expand, damaging the surrounding parts. It's important to note that not unplugging the battery after it's fully charged will affect the battery's lifespan. Combustion phenomenon: After an electric vehicle is fully charged, sometimes internal components may get damaged. At this point, the battery's electrolyte may leak out and slowly seep into the vehicle's wiring. Continuous charging can easily ignite the electrolyte. There are many wires near the battery, and if these wires are burned, the electric vehicle may also experience a combustion phenomenon, posing significant risks to the safety of people and property nearby.

How Far Can a 72v20ah Battery Run?

72v20ah can run about 80 kilometers. 72v20ah indicates that the total voltage of the battery is 72v, using six 12v batteries, with a current of 20ah. The battery is the power source of an electric vehicle, and most electric vehicles are equipped with lead-acid batteries, whose lifespan is calculated based on charge and discharge cycles. The battery is afraid of being undercharged, and keeping it fully charged can extend its lifespan. The correct way to use the charger is: 1. Ensure that the AC power supply matches the charger's input voltage; 2. Ensure that the charger's output voltage matches the battery's rated voltage; 3. First plug in the charger's connector to the battery box, then plug in the AC power plug; 4. The charger should be used indoors, protected from moisture and vibration, and must not be covered during charging. It should be placed in a well-ventilated and heat-dissipating area.

What is the best cleaner to use for car washing?

It is best to use a dedicated car wash cleaner. Dedicated cleaners are neutral, which means they won't harm your hands or damage the car's paint during the washing process. Some specialized car wash cleaners contain natural wax components that can enhance the shine of the car's paint after washing. Avoid using laundry detergent for car washing, as it is alkaline and can cause corrosion to the paint, shortening its lifespan. Use a soft cotton brush for washing, as it has good water absorption and won't harm the car's paint. Many car owners try to save water by using only one bucket of water for washing, but this can damage the paint. Sand and small stones from the car's surface can get into the water with the washcloth, and using such water can scratch the paint. Don't wash your car too frequently just to keep the paint clean, as excessive washing can dull the paint's gloss. Generally, washing the car once a week is ideal.
