The best way is to use DC fast charge.
Because DC fast charging is faster than AC charging, it can charge the battery faster, and AC charging is slower, and it takes longer to full the battery.
At the same time, the DC fast charge can automatically adjust the battery charge when charging, which is relatively safe. In addition, the lithium-ion batteries used in some vehicles have a high tolerance and can support a higher power fast charge, so the use of DC fast charge will be a faster, time-saving and labor-saving way to charge.
It should be noted that the battery needs to be protected when using fast charge to avoid damage to the battery due to long-term high-power charging. In daily use, slow charging may be more secure and can help the battery better maintain a healthy state.
