Basic Architecture of Hybrid Drive Trains
Below, we show the Basic Architecture of Hybrid Drive Trains and describe various parts of this Hybrid Drive Train –
A hybrid drivetrain uses a variety of power sources to move a car forward. The core architecture of hybrid drive trains is made up of various essential parts –
The Internal Combustion Engine (ICE), which is usually powered by petrol or diesel, is the first type of engine. This is the main power source since it burns fuel to produce mechanical energy.
Secondly, the drivetrain incorporates electric motors. These motors supply additional power and are run on batteries or other energy storage devices. They can function both independently and in conjunction with the ICE, which is especially useful when accelerating or travelling at a slow speed.
For the vehicle’s wheels to get power from the ICE and/or electric motor, the gearbox system is essential. A specialized gearbox can accept both power sources in certain configurations.
Regenerative braking or the internal combustion engine (ICE) can refill the electrical energy stored in a battery pack, which is then used by the electric motor(s). Depending on the intended electric-only range and hybrid configuration, its size and capacity change. It is the most important part in the architecture of hybrid drive trains
Power transfer between the ICE, electric motor(s), and battery pack is controlled by the Power Control Unit (PCU). It controls how electric motors operate and makes it easier to switch between electric and hybrid modes smoothly.
When braking, kinetic energy is captured by a regenerative braking system and transformed into electrical energy to replenish the battery pack. By recycling energy that would otherwise disperse as heat, this improves efficiency overall.
A hybrid control system keeps an eye on a number of variables, including driver inputs, battery level, and vehicle speed. It maximises fuel efficiency and performance by optimising drivetrain operation and figuring out how best to use available power sources.
When combined, these parts provide automobiles with internal combustion engines better performance, lower emissions, and increased fuel efficiency. Depending on the brand and kind of car, certain configurations may change.
