Yes, battery charging has fast charge and slow charge.
Fast charge can reach or approach the fully charged state of the battery within 1-5 hours, which is suitable for scenarios that require rapid recharge of power, such as emergency charging or fast charging pile charging.
Slow charging is to input the AC current of the power network into the slow charging port of the pure electric vehicle through the charging interface of the AC charging pile, and convert the AC current into DC power through the battery charger inside the car, and then input into the battery to achieve charging. This method takes a long time to charge, but it can protect the battery and extend the battery life. In addition, charging speed and charging time are also one of the main differences between fast and slow charging. Fast charging uses high-power current to charge quickly, which can replenish the battery in a short period of time, but may cause a certain degree of damage to the battery. Slow charging, on the other hand, uses lower power to charge, and although the charging time is longer, it protects the battery and extends its service life.
In addition, during the charging process, the circuit characteristics of fast and slow charging are also different. If the positive and negative electrodes of the battery are mistakenly reversed, the thyristor trigger circuit is reversed off when the slow charge is used, there is no trigger signal, the thyristor is not switched on, and the output current is zero. When the fast charge is short circuited at the two output terminals, the thyristor SCR trigger circuit in the charger cannot work, so the thyristor does not conduct and the output current is zero.
In short, battery charging has fast charging and slow charging, and it is necessary to choose the appropriate charging method according to the actual situation.
.
Fast charge refers to charging the battery in a short period of time with a large current. This charging method can fill the battery in a short period of time, but it will also have a certain impact on the life of the battery. Fast charging is usually used in emergency situations, such as the need for fast charging to meet emergency usage needs.
Slow charge refers to charging the battery for a long time with a small current, which can better protect the life of the battery, and can make the battery more fully charged. Slow charge is usually used for daily charging, such as charging at night or on rest days.
Choose fast charge or slow charge depending on the user's needs and usage. If you need fast charging to meet the needs of emergency use, you can choose fast charging; If you need to better protect the life of the battery and have enough time to charge, you can choose slow charging. It should be noted that whether you choose fast charge or slow charge, you should use the charger that matches the battery, and follow the correct charging method and operating steps to ensure the charging effect and the safety of the battery.

The difference is the battery charging time, the impact on the battery, and the battery charging mode.
1, battery charging: fast charge half an hour can be charged 80%, slow charge to 6~8 hours can be full;
2, the impact on the battery: fast charging will be correct
