Question 1: How to choose between fast charging and slow charging?
Too much concern about battery health
Let’s first introduce AC slow charging
The vehicle obtains AC power through AC charging equipment, which is then converted into DC power by the on-board power supply to charge the battery. Depending on the charging equipment used and the vehicle configuration, the main power levels are 1.8kW, 3.5kW and 7kW. The charging power is small and the charging is slow, so it is called AC slow charging.
Let’s talk about DC fast charging
The vehicle directly obtains DC power through the DC charging pile to complete the battery charging. DC charging has high power and fast speed, and is generally expressed in multiples. The current average multiple is generally above 1C, and it takes less than 1 hour to fully charge. The higher the multiple, the shorter the time,
especially in the range of 30%~80%, the charging speed is faster, generally reaching an average of about 2C, that is, it only takes 15 minutes to charge 30%~50%. Because charging power = charging rate x battery power, the charging power is generally larger and the charging time is shorter during DC charging, so it is called DC fast charging.
Those who are entangled in whether fast charging will affect battery health do not need to worry. BYD batteries were designed with battery safety and durability in mind. Battery management technology is used to maximize battery life and performance. But developing good charging habits will help make the battery more durable. Long-term use of fast charging may cause voltage imbalance of each battery cell in the battery pack and inaccurate power display. At this time, it is necessary to use an AC charging pile to fully charge once, which will help improve the available capacity of the battery pack and the accuracy of SOC display.
Question 2. Sometimes charging is a whole night. Will the charging gun not be unplugged in time after full charging cause overcharging?
No, the vehicle has a complete battery management system, which will automatically end after charging is completed, which will effectively prevent overcharging. Abnormal power outages during charging will also automatically recover, and the power will be replenished in time, so that it can be fully charged the next day.
Question 3. Will the battery be damaged if the gun jumps when charging sometimes?
No, a single charge that is not fully charged will not affect the battery performance, but long-term continuous charge that is not fully charged will affect the accuracy of SOC. At this time, you need to use AC slow charging to correct it.
Question 4, can I charge outdoors in rainy weather?
In order to ensure the charging safety of the car, the car charging port and charging pile have taken into account various harsh environments in advance during the product design and manufacturing process. The charging port and charging gun have a certain rainproof function and can withstand normal rainfall. However, if you find that the socket has been flooded when plugging the gun, you cannot plug the gun to charge at this time. In heavy rainstorms, you should try to avoid charging in the open air; in thunderstorms, it is recommended not to charge the vehicle outdoors.
Question 5, what is the SOC balance point? Why set the soc value?
The SOC balance point is the target value of the vehicle’s power balance, which indicates the power state that the owner expects the vehicle to reach during driving. When the vehicle’s power is higher than the set value, the system power distribution will give priority to electricity to reduce fuel consumption; when the vehicle’s power is lower than the set value, part of the power will be used to generate electricity when the vehicle is driving to increase the power and ensure the vehicle’s power demand.
Question 6: When driving at high speed, should I choose intelligent power conservation or forced power conservation? Do I need to fully charge the battery?
When driving on high-speed roads and there is no charging condition, if the mileage is greater than the pure electric range, it is recommended to set the hybrid model to force power conservation + medium SOC to facilitate more complex road conditions and take into account power and fuel consumption. If the mileage is long and there is no charging condition in the middle, it is recommended to set off after fully charging.
Question 7: How to set the SOC when you need to use external discharge during camping on the weekend?
It is recommended to adjust the SOC value to a higher or maximum value to reserve power in advance, avoid on-site power generation, and improve economy.
