Remove the buckle of the box to open the battery protective cover. All operations on the battery should be performed with the engine off. Take one jumper cable, connect one end to the positive terminal of the dead battery and the other end to the positive terminal of the live battery. Ensure the positive and negative terminals do not come into contact to avoid the risk of a short circuit. Take another jumper cable, first connect it to the negative terminal of the live battery, then connect the other end to the engine block or body of the dead vehicle. After connecting the cables, start the live vehicle to provide a reliable voltage to the dead vehicle. This completes the jump-start process for a car with a dead battery.

I remember jump-starting my friend's Qin several times. The operation is actually quite simple, but safety is key. First, park another car with a normal battery close by, turn off the engine, and put it in neutral. Then, take out the jumper cables—make sure they're of good quality to avoid sparks. Start by connecting the positive terminal of the BYD Qin, usually under the red cover, to the positive terminal of the rescue car. Next, connect the negative terminal of the rescue car to a metal part of the engine as a ground, avoiding direct connection to the BYD's negative terminal to prevent accidents. Wait a minute or two for the current to stabilize, start the rescue car's engine, and let it run for a while. Then, gently press the BYD's accelerator to try starting it. Once it starts, first disconnect the negative ground cable from the BYD, then disconnect the positive cable. Avoid touching any metal parts during the process to prevent electric shock. The BYD Qin is a hybrid, so the auxiliary battery might be in a different location—check under the hood's lower left corner and refer to the manual for confirmation. It's best to keep an emergency kit in the car and regularly maintain the battery to prevent aging.

Last time my Qin ran out of battery, I was so anxious that I had to ask a colleague for help with jump-starting, and that's how I learned this skill. The key points are: turn off the engine and engage the handbrake, then find a sturdy jumper cable. Open the hoods of both cars, connect the red positive clamp of the BYD to the positive terminal of the rescue vehicle, and attach the negative clamp to a metal point on the engine instead of directly to the battery terminal. After starting the rescue vehicle, wait for about a minute before attempting to start the BYD. Once successful, remove the cables in reverse order: first the negative clamp, then the positive. The whole process takes less than ten minutes, but be careful not to let the clamps touch each other or cause sparks. I later checked the BYD manual, which mentioned that hybrid systems might be more sensitive, so extra caution is needed. Now I always carry jumper cables when traveling, just in case of emergencies on the road.

When I first learned to drive, jump-starting was quite nerve-wracking. Later, I found out that jump-starting a Qin isn't difficult. First, prepare another car with a good battery and park it close, then turn off and secure all power sources. Use high-quality jumper cables: connect the red clamp to the positive terminals of both cars, and the black clamp to the negative terminal of the rescue car and a clean metal point on the BYD's engine as a ground. Start the rescue car's engine and let it run for half a minute, then try to start the BYD. After success, remove the connections in the reverse order of how they were connected. The whole process should be quick and steady—avoid dragging it out to prevent short-circuit risks. If it doesn't start after several attempts, there might be other issues, like poor contact or a damaged battery, requiring professional inspection. Regularly avoid frequent discharging to extend battery life.

The jump-start process was actually quite smooth, and I've used it a few times for emergency situations with my Qin. First, find another car with its engine turned off and park them close together. Check that the jumper cables aren't damaged. Connect the red clamp to the BYD's positive terminal first, then to the rescue car's positive terminal. Next, attach the black clamp to the rescue car's negative terminal and connect it to a clean metal part of the BYD's engine as a ground—avoid connecting directly to the terminal. Start the rescue car and wait for about 30 seconds for the current to stabilize, then try starting the BYD. Once successful, immediately remove the black clamp first, followed by the red clamp—don't mix up the order. Wear gloves during the operation to prevent accidents. The BYD is a hybrid, so its battery might be easier to locate as it's positioned toward the front. Regular maintenance, like checking terminals for corrosion, can make jump-starting smoother. Stay calm and don't rush.

Having decades of driving experience, jump-starting is a routine operation, but extra caution is needed when jump-starting a Qin. Ensure both vehicles' engines are turned off and parked at an appropriate distance, and use a reliable set of jumper cables. First, connect the red positive clamp to the battery terminals of both vehicles, then attach the black negative clamp to the metal grounding point on the BYD's engine. Start the assisting vehicle's engine and let it run for about a minute to charge the battery, then attempt to start the BYD to see if it works. After a successful start, disconnect the cables in reverse order without rushing. As a new energy vehicle, the BYD's auxiliary battery is prone to wear, so avoid touching any high-voltage components during the connection to prevent accidents. Regular maintenance and battery voltage checks are recommended to minimize the need for jump-starts, ensuring safer and more reliable driving.
