Charging is the daily life of every new energy vehicle owner. However, charging a new energy vehicle is not as simple as plugging and unplugging the mobile phone. Mastering the correct charging method is particularly important to prolong battery life and avoid accidents.

What are the correct charging methods for new energy vehicles? Does frequent charging damage the battery? Is the current size positively correlated with the charging speed?

Today we will learn about the charging of new energy vehicles~

1. Q: Can it be charged in rainy days?

A: Ordinary rainy days are fine, same with using adapter. The charging port of the new energy vehicle has a certain waterproof ability and is well sealed. It can be charged in ordinary rainy days. However, when plugging and unplugging the charging gun, pay attention to shielding to prevent rainwater from directly entering the charging port, causing a short circuit and affecting the next charging.

In addition, in case of heavy rain, it is recommended to suspend charging first. Because many charging cables are relatively long, if they are damaged and soaked in water, it may cause a short circuit or fire, which is a safety hazard.



2. Q: What are the charging methods for new energy vehicles?

A: Fast charging and slow charging

Pure electric vehicles can be charged by fast charging, slow charging and other methods. Hybrid cars can only use slow charging. The slow charging power is low and the charging time is long, which is suitable for recharging when driving for a long time; the fast charging power is high and the charging time is short, which is suitable for temporary emergency recharging.


3. Q: Will charging the battery overnight cause the wires to overheat and catch fire?

A: Flying line charging is prohibited first! The heating during charging is due to Joule's law:

If there is resistance and current, heat will be generated. If the triangular plug is rusted or corroded, the contact resistance will increase, which will easily lead to overheating during charging. The use of non-standard charging equipment also has the risk of voltage instability, resulting in over voltage and overheating.

The original authentic charging parts meet the national standards and are in good contact, which can ensure the safety of charging, please rest assured to use. Moreover, the charging current will be automatically cut off after the battery is fully charged, so there is no need to worry about "wire heating and fire" caused by the time process.



4. Q: What problems should be paid attention to during the charging process?

A: Just operate according to the prescribed method

Charging is fully automatic and does not require special attention, but charging must be done in a manner that complies with regulations. Charge at a regular charging pile, and it is recommended to unplug the charging gun after the charging pile prompts "charging is over".


5. Q: How can I prolong the battery life?

A: If there are conditions for slow charging, try to choose slow charging as the main option. If there is really no slow charging condition, it is recommended to slow charge at least once a month for balancing. Just like people eat, chew slowly and eat slowly, but it is good for the body. Gobble your food fast, but may upset your stomach.

Keep 50-80% of the battery when parked for a long time. When not driving for several days in a row, try not to let the battery power be too full or let the battery power be too low. Just like "dieting" and "eating" are not good for the stomach, moderate power is more conducive to improving the health of the battery and prolonging the life of the battery.


6. Q: Will frequent fast charging affect the battery function?

A: Frequent fast charging will have a certain impact on the life of the battery, but there are many differences between the power battery of an electric vehicle and the lithium battery of a mobile phone in terms of functional quality, and it will not decay as quickly as a mobile phone.

It is recommended to use fast charging as an emergency measure and try to avoid continuous fast charging.
