Whether a hybrid car can continue to be driven after its battery is damaged depends on the specific technical type. Plug-in hybrid electric vehicles (PHEVs) such as models from BYD, BMW and other brands have engines and motors that can operate independently. In case of battery failure, they can switch to pure fuel mode, though fuel consumption may increase by 30%-50%. For instance, a model with normal consumption of 4L/100km may rise to 6-8L/100km. Conventional hybrid electric vehicles (HEVs) such as the Toyota Prius or Honda Accord Hybrid cannot operate if the battery is completely damaged since their ECVT transmissions require battery participation in power distribution. However, when battery power is insufficient, they can still be driven by the engine with only a 20%-30% power reduction. Range-extended hybrids like certain Nissan models depend entirely on battery power. Battery damage would render the vehicle inoperable, requiring towing for assistance. The 48V mild hybrid system, as seen in the Mercedes-Benz C-Class, only affects the automatic start-stop function, allowing normal operation with a marginal 5%-10% fuel consumption increase. Owners are advised to regularly monitor battery status and prioritize brands offering 8-year/160,000-kilometre battery warranties to mitigate risks.
