“东风.俊风”新能源车辆提供快充模式："Dongfeng. Junfeng" new energy vehicles provide fast charging mode:

快充和慢充是相对概念，一般快充为大功率直流充电，半小时可以充满电池８０％容量，慢充指交流充电，充电过程需６小时－８小时。Fast charging and slow charging are relative concepts. Generally, fast charging is high-power DC charging, which can fill 80% of the battery capacity in half an hour. Slow charging refers to AC charging, and the charging process takes 6 hours to 8 hours.

 电动汽车充电快慢与充电机功率、电池充电特性和温度等紧密相关。当前电池技术水平下，即使快充也需要３０分钟充电到电池容量的８０％，超过８０％后，为保护电池安全，充电电流必须变小，充到１００％的时间将较长。此外，在冬天气温较低时，电池要求充电电流变小，充电时间会变得更长些。 快充是一种应急充电方式，用的是直流充电，这个直流充电的电压一般都是大于电池电压的，需要通过整流装置将交流电变换为直流电，对动力电池组的耐压性和保护提出更高要求;充电电流大，是常规充电电流的十倍甚至几十倍。 刚才说了，能量密度是有理论上限的，超了这个上限基本相当于你当造物主重新创了一个世界，这事一听就不靠谱。既然想把能量密度踏实做上去是比较难的，那么大家更多地选择了去突破功率密度。

The charging speed of electric vehicles is closely related to the power of the charger, the charging characteristics of the battery and the temperature. At the current level of battery technology, even fast charging takes 30 minutes to charge to 80% of the battery capacity. After exceeding 80%, in order to protect the battery safety, the charging current must be reduced, and the charging time to 100% will be longer. In addition, when the temperature is lower in winter, the battery requires less charging current and the charging time becomes longer. Fast charging is an emergency charging method. It uses DC charging. The voltage of this DC charging is generally greater than the battery voltage. It is necessary to convert the AC power into DC power through a rectifier device, which improves the voltage resistance and protection of the power battery pack. High requirements; the charging current is large, which is ten times or even dozens of times the conventional charging current. As I said just now, there is a theoretical upper limit to energy density. Exceeding this upper limit is basically equivalent to re-creating a world as a creator, which is unreliable at first sight. Since it is difficult to make energy density practical, everyone chooses to break through power density.

一来功率密度算是没有理论上限的（其实也不完全见得），As a result, the power density has no theoretical upper limit (in fact, it is not completely seen),

二是功率密度做好了很容易就演变成X分钟X秒钟充满电的大新闻，再加上锂电表兄弟超级电容的掺和（这个本来就是只为了快充放而生的，能量密度特别低，用它全装车走不了多远就要一充，希望大家明白），很容易炒出一片欣欣向荣的革命形式一片大好的一颗赛艇的景象。The second is that the power density can easily evolve into a big news of being fully charged in X minutes and X seconds, plus the addition of the supercapacitors of the lithium battery cousins (this is originally only for fast charging and discharging, and the energy density is very special. Low, you need to recharge it before you can go far with it, I hope everyone understands), it is easy to stir up a thriving revolutionary form and a great scene of a racing boat.

条件许可，我们提倡多用慢充。这样电池寿命可延长20%-30%。Conditions permitting, we advocate multi-use slow charging. This can extend battery life by 20%-30%.
