Why can't the engine start when the BYD F3DM runs out of battery?
2 Answers
When the BYD F3DM runs out of battery, the engine definitely cannot start because the ignition system requires electricity. Below is relevant information about the BYD F3DM: 1. Positioning: As a global leader in new energy vehicles, BYD has been active in the electric vehicle sector. Following its collaboration with Mercedes-Benz, BYD officially announced that the technologically advanced BYD F3DM Low Carbon Edition dual-mode electric vehicle was launched on March 29, 2010. Official images reveal that the vehicle is equipped with a new roof-mounted solar charging system. 2. Powertrain: In terms of powertrain, the BYD F3DM dual-mode electric vehicle is powered by a BYD371QA all-aluminum engine with an output of 50KW, paired with a 75KW electric motor, resulting in a combined output of 125KW. In pure electric mode, the F3DM dual-mode electric vehicle achieves the world's longest range of 100km at that time.
For the BYD F3DM hybrid vehicle, the main reason the engine won't start is likely due to a dead small battery. Besides the large battery used for driving, this car also has a 12V small battery responsible for starting the engine and controlling the system. If the small battery is depleted, even if you press the start button, the engine won't work. I've encountered a similar situation before, and it was immediately resolved after jump-starting. Additionally, the car's intelligent protection system might also come into play. When the large battery's charge is too low, it prevents the engine from starting to avoid damaging the battery. In such cases, it's best to plug in the charger for half an hour and then try switching to hybrid mode to start. When parking, try not to drain the battery completely; keeping at least 20% charge is the safest practice.
