　　When charging new energy vehicles, is it better to charge quickly or slowly?

　　The issue of charging new energy vehicles has always been the focus of people's attention. After all, charging is also a core of the car, and it also determines the driver's experience of using the vehicle. For current new energy vehicles, it is There are two charging methods provided, one is fast charging and the other is slow charging. Fast charging, as the name suggests, uses a large current to fully charge the battery in a specific time, while slow charging means that the charging time is slow and the battery is charged through a constant charge. Current is charged into the battery. For vehicles, is it better to charge quickly or slowly? No matter which charging method is used, it actually does no harm to the vehicle. As for whether fast charging or slow charging is better, it depends on what kind of car usage scenario it is in, and it also depends on the size of the battery capacity. To decide, although fast charging is used as an emergency charging method for vehicles, DC charging is used, but for the battery, the current of regular charging continues. Therefore, if the battery capacity or energy density is limited, use fast charging One situation that easily occurs when charging is that the battery becomes hot, which will directly affect the service life of the vehicle's battery. Just like a mobile phone, under the impact of large current, the battery will become hot, which will directly cause the battery to become hot. Internal aging is accelerated, and if the battery capacity density is high, then there is basically no problem. At the same time, for this kind of thing, it also depends on the management of the vehicle's battery BMS. For slow charging, it is charged with household electricity. In fact, simply speaking, what is the input voltage of the battery? He will send as much voltage as possible, so this is like when a faucet is discharging water, slowly discharging water, and then until the water is filled in the water storage container, that is to say, no water will appear during the process of discharging water. Splashing, so in terms of slow charging, it is only suitable for power batteries with the same battery capacity. At this point, you can basically understand some of the advantages and disadvantages of fast charging and slow charging. At the current charging level of the battery, fast charging takes about 30 minutes. When the battery is charged to 80%, it becomes slow charging. In order to ensure the safety of the battery, the charging current will become smaller until it is charged to 100%. The charging technology of electric vehicles It has been gradually improved since the development, especially after the implementation of the national standard. Charging, whether it is mite charging or fast charging, is very strict. At the same time, the charging process is also monitored in real time, so whether it is fast charging or slow charging, only Only by choosing a charging mode that suits your vehicle's battery can you better protect your vehicle.
