Electrical systems of hybrid vehicles
Hybrid vehicles combine a traditional internal combustion engine (ICE) with one or more electric motors. The electrical system is an integral part of a hybrid vehicle, providing additional power, improving fuel efficiency and reducing emissions.
Battery
The battery is the main source of electricity for electric motors. Hybrid vehicles typically use high-voltage lithium-ion batteries that can store and release large amounts of energy. They provide power to the electric motors during electric-only operation and help regenerate energy during braking.
Electric motor
Electric motors convert electrical energy from the battery into mechanical energy that powers the wheels. Hybrid vehicles typically feature one or more electric motors that work in conjunction with the combustion engine to provide optimal performance and fuel economy.
Inverter
The inverter converts direct current (DC) from the battery into alternating current (AC) for the electric motors. It can also convert AC generated by electric motors during regenerative braking into DC to recharge the battery.
DC-DC converter (DC-DC)
The DC-DC converter converts the battery voltage to a lower voltage to power the car’s electronic components, such as the headlights, power windows, and stereo.
Power Management Module (PCM)
The PCM is the central computer of the hybrid vehicle’s electrical system. It controls the flow of energy between the battery, electric motors and internal combustion engine. The PCM also optimizes battery performance and ensures system safety.
Regenerative braking
When the driver brakes, the car’s kinetic energy is converted into electrical energy using electric motors that act as generators. This energy is stored in the battery, improving fuel efficiency.
Electric mode
Many hybrid vehicles can operate solely on electric power for short distances. This allows you to drive with zero emissions and save fuel in city driving.
Charger
To recharge the battery, most hybrid cars are equipped with built-in chargers. They plug into a regular outlet and can fully charge the battery within a few hours.
High voltage electrical system
The electrical system of a hybrid vehicle operates at high voltage, typically 300-600 volts. This requires special insulation and safety components.
