Plug-in Hybrid Refuelling and Charging: Never at Once
The BYD Qin L DM-i manual says refuelling and charging must not happen at the same time. How to plan the order at a service area safely.
Plug-in hybrid refuelling and charging: why they can't be done at the same time
Scope: 2026 Qin L DM-i, China mainland; PDF p. 150; safety limits only
Saving time can't come before safety
This car's manual states clearly that refuelling and charging must not take place at the same time. Both are ways of topping up energy, but that doesn't mean they can be done in parallel. At a service area, plan the order in advance: don't have passengers operate the two sets of equipment separately, and don't ask for fuel while charging equipment is connected. [1]
Be clear about the car's status when talking to staff
We suggest telling on-site staff whether the car is connected to any equipment, and carrying out every step strictly in line with the vehicle's and the site's safety requirements. Don't assume the car is ready to refuel just because the engine is silent. Specific start/stop and equipment shut-down procedures are covered by the relevant instructions and by trained staff; this article does not repeat them. [1]
If anything is wrong, stop
If you smell fuel, see a leak or see equipment smoking, don't switch to the other kind of top-up just to finish the trip. Make sure people are safe and contact the site and emergency services. This article does not cover dealing with leaks, unplugging faulty equipment or opening the fuel tank; trained people should handle these based on the situation on site. [1]
