Do Hybrid Cars Need Charging Stations?

Whether to install a charging station for a hybrid car mainly depends on usage. If the daily driving distance is very short and the electricity consumption is minimal, there is no need to install a charging station. More information about hybrid cars is as follows: Non-Plug-in Hybrid: The conventional working principle of non-plug-in hybrid power is to convert excess engine output or kinetic energy into electrical energy through an energy recovery device during braking or high-speed cruising and store it in the battery. This energy is then converted into power during low-speed phases to replace the engine in providing power to the vehicle. Plug-in Hybrid: Plug-in hybrids require charging. When a plug-in hybrid vehicle travels long distances, it primarily uses the internal combustion engine as the power mode. Conversely, for short distances, it uses electric drive. When the battery power for the electric drive is depleted, it switches to internal combustion engine drive, which increases fuel consumption. Therefore, plug-in hybrid vehicles need to charge their batteries.
