Charging the battery of your plug-in hybrid vehicle is highly recommended to maximize efficiency and power. Without charging, all-electric driving will be limited, and power reserves for the eBoost function will be much lower. For optimized efficiency, BMW recommends regular charging overnight.
BMW plug-in hybrids can also charge while driving. Regenerative braking allows the plug-in hybrid to regain part of its energy. In addition, charging can also take place during the journey with the function known as Battery Control Mode. This mode maintains the charge of the high-voltage battery constantly at the desired level or increases it to the preset value, by having the electric motor function as a generator. In this way, for example, it is possible to use Battery Control Mode during a drive on the highway to protect or even increase the electric power reserves so that a subsequent urban route can be covered with electric driving and without any local emissions.
Even if you don’t have time to catch a charge, your PHEV will still get you where you need to go. When the battery is fully discharged, the BMW TwinPower Turbo engine automatically takes over.
