First of all, Tang DM-i supports both DC and AC charging, generally DC is called fast charging, AC is called slow charging, but the speed here is relative, not absolute. The maximum power of DC fast charge is 25 kW (that is, it can charge 25 degrees per hour), and it is backward compatible (for example, 12 kW DC charging pile can charge Tang DM-i, but the maximum power can only reach 12 kW). Ac slow charge maximum power of seven kilowatts, downward compatible.

The charging equipment delivered by the Tang DM-i car has 1.6 kW portable charging gun, 3.3 kW or 7 kW wall mounted charging pile (the wall mounted charging pile varies according to the configuration of the model) and 25 kW AC direct fast charging adapter.
< br >
The 1.6 kilowatt portable charging gun can be plugged into the plugboard at home like a mobile phone charger to charge, because the general household plugboard is 2500 watts, but the maximum power of the charging gun is only 1600 watts, which is not as big as an induction cooker. However, because this charge lasts a long time, generally more than 10 hours, it is necessary to use the regular national standard plug board and 2.5 square copper core wire, otherwise it is easy to cause overheating of the line leading to fire.

3.3 kW or 7 kW wall hanging charging pile used to be sent directly with the car, installed by yourself or find a professional electrician after going home, and now it is applied for after buying a car in BYD car app or small program, and then there is a professional master to install it free of charge (although it is free, but if the cable or door distance is too far, it will charge a certain service fee). But there are standards, don't worry about that).

The 25kW AC to direct fast charge adapter is generally used in commercial charging stations, of course, if you install your own DC charging pile like me, you can use it.

Let's talk about the charging power and charging time. Charging power is the amount of electricity rushed into the car every hour, for example, the maximum charging power of Tang DM-i is 25 kilowatts, that is, you can rush the car into 25 degrees of electricity every hour, my medium battery capacity is 21.5kWh (that is, 21.5 degrees), then the time required from completely no electricity to full is (21.5 degrees). 25≈0.86X60 is equal to 51.6) 52 minutes, in actual use, because we generally do not use up the car's power completely, and according to the instability factors such as voltage and outdoor temperature, the charging time will be deviated from the theoretical time. When charging Tang DM-i, the dashboard will give the current charging power and the estimated time required. From my use in recent years, the estimated time given is still relatively close to the actual charging time, so you can refer to it.

Whether it is DC or AC charging, the charging power can be compatible down or up. The real charging power depends on the limit value of the vehicle or charging pile, for example, my car maximum support AC 7 kW charging, if I use 1.6 kW charging gun charging, then the maximum charging power is 1.6 kW, if I use 30 kW AC charging gun charging, then the maximum power can only be 7 kW. And the car DC charging maximum support 25 kW, if I use 12 kW DC pile charging, then the maximum power will only reach 12 kW, if I use more than 25 kW DC charging pile charging (such as 60 kW, 120 kW, 240 kW), then the maximum power is 25 kW.

Finally, let me tell you about some precautions in charging.
< br >
The 1.6kW charger is mainly for emergency and convenience, so it can be used without grounding, but it is not recommended that big parents use this time without grounding, and it is not recommended that you use the so-called grounding treasure (because this thing is similar to a liar, mainly through the illusion of telling the car has been grounded, the actual ground is not grounded, so the grounding treasure has no safety protection). For long-term use of flying wire fixed charging, it is strongly recommended to ground at one end of the plugboard to solve the problem.
< br >
For the wall hanging charging pile, be sure to ask a professional master to install, if you buy your own second-hand installation, you must be correctly grounded (but not grounded seems not to be used).
< br >
For AC to DC joints are generally used in public commercial charging stations, those are standard grounding, rest assured to use.
< br >
For the waterproof and anti-theft performance when charging, it is not convenient to write, so I have a test video on the home page, you can find out.

Finally, to say an aside, for Tang DM-i, he is a hybrid car, can be charged separately, can also be used separately, and whether it is urban or rural, as long as it is connected to the place can be charged, but the charging speed is a matter of.
The difference lies in the difference in charging voltage. Byd Tang dm I car charging fast charge 60 volts, and slow charge is 58 volts, so the fast charge voltage is higher, to be used reasonably
1 The difference between fast charging and slow charging is the charging speed and charging efficiency.
2 The fast charge of BYD Tang dm can fill the battery faster, saving the user's charging time.
Fast charging technology uses higher charging power and optimized charging algorithm, which can provide faster charging speed.
3 Slow charge is a relatively low charging power, charging time is longer.
Slow charge A more gentle control of the battery charging process can extend the service life of the battery.
4 Choose fast charge or slow charge mainly depends on the user's needs and usage scenario.
If the user needs fast charging, such as when traveling or when the phone is urgently needed, fast charging is a better choice.
If the user is more concerned about battery life and safety, slow charging is more suitable. In addition, the development of fast charging technology is also improving, and there may be faster and more efficient charging methods in the future.
Users can consider the future trend of charging technology when choosing.
The fast charge and slow charge of BYD Tang DM have the following differences: Fast charge refers to the use of high-power charging equipment, which can fill the battery in a short time, usually taking 30 minutes to 1 hour; Slow charge refers to the use of low power charging equipment, charging time is longer, usually takes 6-8 hours.
Fast charge is suitable for long trips or when charging is urgently needed, while slow charge is suitable for charging at home or at work. Fast charging may have some impact on battery life, while slow charging has less impact on battery life. Therefore, according to the needs and the limitations of charging time, you can choose the appropriate charging method.
Fast charging requires a special charging pile, and slow charging only requires ordinary household electricity to complete the charging
