What are the reasons for slow charging of new energy vehicles?

The reasons for slow charging of new energy vehicles are: 1. Damage to the fuse inside the battery; 2. Poor contact between the fuse tube and fuse holder, plug and socket, charger and power source; 3. Fault in the battery's internal plug-in. The maintenance methods for new energy vehicles are: 1. Check for paint damage, functionality of lights, aging degree of wiper blades, tire wear and tire pressure; 2. Replace the air filter; 3. Check and replenish coolant, brake fluid, and windshield washer fluid; 4. Check the interface connections of the power system and the insulation protection of the wiring; 5. Check the state of the battery cells; 6. Check the chassis for scratches and whether the depth of the scratches could lead to water ingress in the chassis; 7. Check for water leakage in the chassis; 8. Check for any damage or aging in the chassis wiring harness; 9. Check the thickness of the brake pads.
I often notice how frustrating it is when new energy vehicles charge slowly. Primarily, the chemical reactions in the battery slow down in low-temperature environments, naturally reducing the charging speed—especially in winter when charging in underground parking garages, sometimes taking several hours. Additionally, the power of charging piles varies significantly; home AC charging piles have lower power and naturally charge slower, far from the speed of DC piles at fast-charging stations. Moreover, battery aging also affects performance—older vehicles with reduced battery capacity charge more slowly. The vehicle's protection system may also intentionally limit charging speed to prolong battery life and prevent overheating damage. Solutions include charging during warmer weather whenever possible or using dedicated fast-charging piles to improve efficiency, while regularly checking battery health to ensure optimal performance.
I have a deep impression of the slow charging experience when driving an electric car frequently. Personally, I think the primary issue is the inadequate charging equipment. For example, many outdated public charging piles have insufficient power, and it feels like charging overnight barely adds any significant charge. Battery temperature also plays a crucial role—summer is better, but in winter when it's freezing, the battery gets too cold, and the charging speed drops by more than half. Additionally, vehicle settings can impose limits. Sometimes, the car automatically reduces speed for safety reasons, and you have to adjust the settings to speed it up. Unstable power grids or limited electrical capacity in residential areas can also slow down the process. I recommend installing a home fast-charging device to improve efficiency or booking fast-charging stations in advance to save time. Regular vehicle maintenance shouldn’t be overlooked—these small details can make charging much smoother.
