And this kind of private reform behavior, not only can not enter the fast charging station, but also lead to the loss of vehicle warranty, the most serious is related to safety issues. Does not meet national standards, does not have reliability for the modification principle, the business is also directly clear: modified plug mixed electric port, that is, through a DC charging controller, directly connected with the power battery. As for the power input method, it is the same as the kinetic energy recovery principle of the vehicle, and DC-DC step-down recharge is used. The slow charging port harness is too small, and the charger has voltage limits, and the direct replacement of the fast charging port is not reliable, but the battery kinetic energy recovery system can withstand, and the charging voltage and current can be higher.
A: Kinetic energy recovery is safer than fast charging, but relatively not fast enough.
1. Kinetic energy recovery refers to converting kinetic energy generated during vehicle braking into electric energy, so as to realize energy recovery and saving. Since no external energy input is required, kinetic energy recovery is safer than fast charging.
2. However, compared with fast charging, the recovery time of kinetic energy is relatively long, and it takes a period of riding to obtain more electric energy. Therefore, fast charging is more convenient and fast when it is in urgent need of charging.
Although kinetic energy recovery can store the kinetic energy generated during braking in the battery, there will be a certain amount of energy loss in this process, and fast charging will cause higher temperature and pressure inside the battery, resulting in shorter battery life, and there are safety risks. Safe charging methods can better maintain the health and safety of the battery. Of course, if there are no clear requirements for battery life and safety, you can also consider using kinetic energy recovery to charge fast
