According to the changes of The Times, more and more people are now using new energy vehicles, and electric vehicle charging is also divided into fast charging and slow charging modes, so electric vehicle fast charging and slow charging, which is better for the car?
Compared with fast charging and slow charging, slow charging is better for the car. Mainly because fast charging, it is easy to appear electrode concentration polarization, fast charging of the vehicle will cause battery damage. Generally, fast charge can fill the battery within one or two hours, but fast charge can choose fast charge in the case of emergency recharge, if we are not in a hurry to use the vehicle, it is recommended to choose slow charge.
Slow charging can fill the vehicle in about 8 hours, and the current and power are relatively small during the charging process, which can protect the battery and extend the service life of the battery. The current and voltage of the fast charge itself are relatively high, and the battery will be in a high temperature state when charging, which is very damaging to the battery. In contrast, the safety factor of slow charging is very high, our charging habits try to slow charge, fast charge as a supplement, and try not to fast charge in emergencies.
Slow charging and fast charging are both relatively safe ways to charge, but safety is still different.
Slow charging is safer because it charges the battery over a longer period of time, the charge gradually accumulates, and the heat dissipation is more uniform, which will not cause overheating. At the same time, the voltage and current of the slow charge are also relatively stable, and will not cause excessive pressure on the battery, and the damage to the battery life is less.
The safety of fast charging should be relatively paid attention to. Although fast charging can fill the battery in a short time and improve the charging efficiency, due to the large fast charging flow and relatively large voltage fluctuations, it will accelerate the heat accumulation of the battery. This requires electric car owners to pay attention to the fast charging power of the electric vehicle and the rated charging power of the battery when choosing a fast charger to avoid excessive heat accumulation damage to the battery.
In general, whether it is slow charging or fast charging, users need to pay attention in daily use, comply with the correct charging method and charging time, so as to ensure the safety and life of electric vehicles.
Compared with fast charging, slow charging is safer than fast charging. The current and voltage of fast charging are higher, and the battery will produce a high temperature state when charging, which will be purely unsafe factors.
