Talking about the problem of charging, in fact, the most difficult to master is the correct charging. Charging is divided by charging current, and there is a difference between fast charging and slow charging. From the point of view of charging, there are differences between constant current charging and pulse charging. Many people have such a problem, whether it is fast or slow charge. Let's first take a look at what is fast charging and what is slow charging, with a nominal capacity of 1C of a battery, at 0.1-0.2C charging current for slow charging, > 0.5C for fast charge, > 0.8C for ultra-fast charging.

Fast charge or slow charge is a relative concept, and the capacity of the battery itself is greatly related. Going back to the previous question, is it better to go fast or slow? There is no fixed answer.

Many people think that slow is good, that fast charging will hurt the battery, fast charging will hurt the battery. The answer is yes, but the reason is not \"high current charging hurts the battery\" as many people think. At best, the large current is an accomplice, and the real cause is the heat, the heat caused by the large current. Too high temperature has a great impact on battery life, so the high current is not terrible, the headache is how to solve the problem of heat. Speaking of this, it is necessary to introduce the concept of constant current charging and pulse charging. In the slow charge, basically all chargers use the constant current charging method, so the circuit design is relatively simple and easy to achieve.

Because the charging current is in the slow range, it does not cause the problem of overheating the battery. When it comes to the problem of charging with fast current, the constant current method can no doubt avoid the problem of overheating of the battery. Therefore, the constant current method is abandoned and replaced by a pulse mode, which can be seen from the waveform. The output of the charging current is not a straight line, but a sine wave.

At the peak of the wave, the current is maximum, and then immediately into the trough, there is almost no current. The purpose of this design is to allow the battery to have a recovery time, thereby reducing the heat generated by the large current, so that the battery heat control at an acceptable level.
The main difference between the ideal one fast charge and slow charge is the difference in charging speed.
The Ideal ONE is an extended-range model, equipped not only with a fuel engine, but also with dual motors. In terms of pure electricity, the car is equipped with a 40.5KWH battery, which supports both fast and slow charging, slow charging time is 6 hours, and fast charging can be charged to 80% in 30 minutes. So fast charge slow charge time is still quite a big difference,
A: The fast charge current of the ideal one is larger than the slow charge current
The ideal one's fast charge is fast charge, and the slow charge is slow charge.
