Song requires approximately 18 kilowatt-hours for a full charge. Below is an extended introduction: Powertrain of BYD Song: The BYD Song is equipped with a hybrid system consisting of a 1.5T engine and two electric motors. The two motors are positioned on the front and rear axles respectively, enabling all-wheel drive functionality. Additionally, the BYD Song has a pure electric range of 70km and can accelerate from 0-100km/h in 4.9 seconds. Interior of BYD Song: The interior of the BYD Song features some diagonal line designs and chrome accents, creating a dynamic atmosphere. The steering wheel bears a red "Song" character at its base, highlighting the vehicle's identity.

















I've been driving the Song DM-i hybrid for two years now, and a full charge typically uses around 18.5 kWh. From 0% to 100% battery display, the charging station shows an actual consumption of over 19 kWh, as there's always a 5%-10% loss during conversion, which is quite common. I remember my first full charge took three hours with a home slow charger, and the cost was really low—just 0.5 RMB per kWh, totaling less than 10 RMB for 110 km of pure electric range. For my daily city commute, charging once a week is enough, but in winter, using the heater drains the battery faster, while summer is better. I’d advise beginners to avoid frequent fast charging—it’s quick but affects battery lifespan; slow charging is more reliable. Also, battery capacity varies by model configuration—some versions of the Song have slightly larger batteries, around 20 kWh, so check the manual or app before purchasing to calculate.

After driving the Song for a few months, I've calculated several charging records. On average, a full charge uses about 19 kWh, while the charging station shows an actual input of around 21 kWh, which is normal due to energy loss. In terms of cost, public charging costs 1.2 yuan per kWh, totaling around 24 yuan for a full charge, which can cover over 100 kilometers—much cheaper than refueling. I save several hundred yuan on fuel each month. Charging at home is even more economical, with off-peak rates as low as 0.3 yuan per kWh, bringing the total cost down to just over 6 yuan. I've developed a habit of starting to charge when the battery drops to 20% to avoid deep discharge, which can harm the battery. A reminder: don’t forget that running the AC or entertainment system during charging consumes extra power—optimizing habits can improve range. In the long run, this kind of electric vehicle is both eco-friendly and cost-effective, making it worth trying.

From a technical perspective, the Song's battery capacity typically ranges from 18 to 20 kWh. The DM-i model requires this amount of electricity for a full charge. However, the actual charging input is slightly higher, approximately 19 to 21 kWh, due to conversion efficiency losses. Depending on the model configuration, a larger battery provides a longer pure electric range. For example, a 20 kWh battery can cover about 120 kilometers. Charging time depends on the power output: slow charging takes around three hours, while fast charging can be completed in under an hour. For daily driving, it's advisable not to wait until the battery is completely depleted before recharging. Maintaining the battery charge between 20% and 80% helps protect the battery. Calculated this way, the electricity cost per kilometer is just a few cents, making it extremely cost-effective.

I've been using the Song for over half a year now, and it's normal to consume 18 kWh for a full charge. Each time the app shows the battery charging from 0% to full, the actual electricity consumption is around 20 kWh. Charging at home with slow charging takes a little over two hours. The electricity cost is very cheap, averaging about 0.7 yuan per kWh, with a total cost of around 14 yuan to cover a week's commute. My daily habit is to charge when the battery reaches 30% to avoid too frequent charging, which helps extend the battery life. Once during a long summer trip, the high air conditioning usage caused faster power consumption, but it was quickly replenished. Overall, charging this car is convenient and worry-free, and it's easy for beginners to get used to.

After purchasing the new Song, I quickly familiarized myself with the charging capacity. The salesperson mentioned that the 18.3 kWh battery requires about 19 kWh for a full charge in actual consumption. During my first test charge from empty to full, the charging station showed an input of 18.5 kWh, indicating some wastage. Now, I make it a habit to check the battery level weekly and use slow charging when the battery is low, avoiding fast charging when not in a hurry to save money and protect the battery. I calculated the cost at about 0.5 yuan per kWh, totaling less than 10 yuan, saving several cents per kilometer compared to a gasoline car. Beginners should note not to charge during high temperatures as it affects efficiency. With time and practice, you'll get the hang of it.
