Can the Song Plus DM-i Run Without Charging?

[DelHolden]

The Song Plus DM-i can operate without charging. As a plug-in hybrid, the Song Plus DM-i's engine will charge the battery when it's depleted, though this is less efficient and will increase fuel consumption. Introduction to Plug-in Hybrids: A Plug-in Hybrid Electric Vehicle (PHEV) is a type of new energy vehicle that bridges the gap between pure electric vehicles and traditional fuel-powered cars. It features both the conventional car components like the engine, transmission, drivetrain, fuel system, and fuel tank, as well as electric vehicle components such as the battery, electric motor, control circuit, and a larger battery capacity with a charging port. Advantages of Plug-in Hybrids: PHEVs combine the benefits of pure electric vehicles (EVs) and hybrid electric vehicles (HEVs), enabling zero-emission driving in pure electric mode while also extending the vehicle's range through hybrid operation.

I've been driving the BYD Song PLUS DM-i for a while now. This car is designed as a plug-in hybrid, and when the battery runs low, the engine automatically charges it to keep you going. Simply put, it can keep running without ever needing to be charged, no problem. The system has a strategy called SOC retention, which basically maintains the battery level between 20%-30% to prevent complete depletion. However, fuel consumption increases—averaging around 4 liters per 100 km when charging, and 5-6 liters when not charging. When the engine kicks in more frequently, the noise level also rises. I've also noticed details like significant fuel consumption fluctuations in city traffic jams, potentially costing an extra 10% in fuel. In the long run, occasional charging is necessary to keep the power delivery smoother.

I've been using the Song PLUS DM-i for commuting to work for almost a year now, with plenty of highway driving on weekends. I'm usually too lazy to charge it, but it can still run for hundreds of kilometers without issues. The acceleration and startup are great, but the fuel consumption data on the dashboard shows a noticeable increase. A single charge gives over 100 kilometers of pure electric range, saving a lot on electricity costs. However, when not charging, the engine works harder, and the fuel gauge drops quickly, adding a few hundred yuan to monthly fuel expenses. The comfort level is a bit lacking, and the engine noise during acceleration is quite annoying. Overall, I tried not charging it for three consecutive months, and the car didn't break down, but it feels less economical than occasionally charging it.

Is it economically worthwhile? When charging, the fuel consumption is low, costing just a few cents per kilometer for electricity; if not charging and relying solely on fuel, it consumes an extra 1-2 liters per 100 kilometers. Based on driving 2000 kilometers in the city, that's an additional two to three hundred yuan in fuel costs per month. I usually calculate expenses carefully—charging saves money, while not charging offers convenience but empties the wallet faster. The fuel-saving potential of hybrid vehicles is wasted if not utilized, so it's better to charge occasionally.

Regarding battery maintenance, I've seen many vehicles that haven't been charged for extended periods, resulting in decreased lithium battery health. The BYD Song PLUS DM-i's battery requires regular charge-discharge cycles, as consistently low charge states can lead to premature aging and reduced lifespan. It's recommended to charge it at least once a week to above 80% to maintain optimal performance. Based on my experience, daily driving isn't an issue, but preventive maintenance can save you from costly major repairs.
