Charging is the daily task of every new energy vehicle owner. However, the charging of new energy vehicles is not as simple as that of mobile phones. 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? Is frequent charging harmful to the battery? Is there a positive correlation between the current and the charging speed?

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

A: Fast charge and slow charge

Pure electric vehicles can be charged using fast charging and slow charging. Hybrid electric vehicles can only use slow charging. The slow charging power is low and the charging time is long, so it is suitable to supplement power when the vehicle stops driving for a long time; The fast-charging power is high and the charging time is short, which is suitable for temporary emergency power supply.

Q: Can I charge it on rainy days?

A: Ordinary rainy days are OK. The charging port of new energy vehicles has a certain waterproof capacity and good sealing. It can be charged on ordinary rainy days. However, pay attention to shielding when plugging in and out the charging device to prevent rainwater from directly entering the charging port, resulting in a short circuit and affecting the next charging.

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

Q: Will charging all night cause the wires to heat up and catch fire?

A: First, do not charge the flying wire! Heating during charging is due to Joule's Law:

Resistance and current will generate heat. If the triangle plug is rusted or corroded, it will cause the contact resistance to increase, which may easily lead to overheating of charging. If non-standard charging equipment is used, there is also a risk of voltage instability, resulting in overvoltage and overheating.

The original genuine charging parts meet the national standards and are in good contact, which can ensure charging safety. Please feel free to use them. Moreover, after the battery is fully charged, it will automatically cut off the charging current, so there is no need to worry about the time process and cause "wire heating and fire".

Q: What should be paid attention to during charging?

A: Operate as specified

The charging is fully automatic, and no special attention is required, but the charging must be carried out in a way that meets the regulations. Charge at the regular charging point, and it is recommended that the charging point prompt "charging is over", and then unplug the charging gun. Finally, do not charge the flying wire!

Q: How to prolong the battery life?

A: If there are conditions for slow charging, try to choose slow charging as the main method. If there are no conditions for slow charging, it is recommended to charge slowly at least once a month for balancing. It's like eating slowly, but it's good for your health. Eat fast, but your stomach may be uncomfortable.

Park for a long time to maintain 50-80% of the power. When not driving for several days, try not to make the battery full or low. Just as "dieting" and "eating" are bad for the stomach, moderate power consumption is more conducive to improving the health of the battery and prolonging the battery life.

Q: Will frequent fast charging affect the battery function?

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

It is recommended to take fast charging as an emergency means and try to avoid continuous fast charging.

Q: Why can't fast charging fully charge the battery?

A: This is determined by the characteristics of the battery. When the battery power exceeds 80%, the charging speed will decrease significantly. It's like taking a water cup to collect water. When the faucet is turned on the most, the water comes the fastest, but it is always filled with dissatisfaction because it will continue to overflow. In the end, you still need to turn down the tap to make the cup full. Overflowing water will not damage the cup, but overcharging will damage the battery.

Q: Does the higher the current, the faster the charging speed?

A: It is not rigorous to say that the greater the current, the shorter the charging time. So how to judge?

There is a technical term called "charge-discharge ratio C". Therefore, the simplest algorithm can simply estimate the charging time by dividing the charging power by the power of the charging pile.

After mastering this knowledge, you will understand the charging time, charging speed, charging method, and charging safety. Of course, the most important thing is "action". In the daily charging process, remember to strictly abide by the rules.
