As the demand for more fuel-efficient and eco-friendly vehicles continues to grow, automobile manufacturers are constantly developing innovative technologies to meet these demands. One such technology is the mild hybrid system, which Volvo has implemented in many of its vehicles. In this article, we will explore how Volvo’s mild hybrid system works and the benefits it offers to drivers.
What is a Mild Hybrid System?
A mild hybrid system, also known as MHEV (Mild Hybrid Electric Vehicle), is a type of hybrid system that combines the internal combustion engine with a small electric motor. Unlike a full hybrid or a plug-in hybrid, a mild hybrid system cannot operate solely on electric power. Instead, it assists the combustion engine by providing additional power during acceleration and reduces the load on the engine during deceleration and braking.
How Does Volvo’s Mild Hybrid System Work?
Volvo’s mild hybrid system comprises three main components: a 48-volt battery pack, an Integrated Starter Generator (ISG), and a DC/DC converter.
1. 48-volt Battery Pack:
The 48-volt battery pack is significantly larger than the standard 12-volt battery found in traditional vehicles. It stores the electrical energy captured during regenerative braking and provides power to the ISG to assist the combustion engine.
2. Integrated Starter Generator (isg):
The ISG is a compact electric motor located between the engine and the transmission. It serves multiple functions:
- Assist the engine during acceleration: The ISG provides an extra burst of power to assist the engine during acceleration, resulting in improved performance and reduced fuel consumption.
- Regenerative braking: When the driver applies the brakes or slows down, the ISG captures the kinetic energy and converts it into electrical energy, which is then stored in the 48-volt battery for later use.
- Engine start/stop functionality: The ISG enables the engine to shut off automatically when the vehicle comes to a stop, such as at a traffic light, to save fuel. When the driver releases the brake pedal, the ISG quickly restarts the engine.
3. Dc/dc Converter:
The DC/DC converter is responsible for converting the 48-volt power from the battery pack to the traditional 12-volt power required by the vehicle’s electrical system. This ensures compatibility with the existing electrical components.
The Benefits of Volvo’s Mild Hybrid System
Volvo’s mild hybrid system offers several benefits to drivers:
- Improved fuel efficiency: The mild hybrid system helps reduce fuel consumption by assisting the engine during acceleration and enabling engine start/stop functionality.
- Reduced emissions: The electric motor in the mild hybrid system helps reduce emissions by providing additional power and reducing the load on the combustion engine.
- Enhanced performance: The extra power provided by the mild hybrid system improves the overall performance of the vehicle, resulting in better acceleration and a smoother driving experience.
- Seamless integration: Volvo’s mild hybrid system seamlessly integrates with the existing vehicle architecture, requiring minimal changes to the design and manufacturing process.
- No range anxiety: Unlike fully electric vehicles, mild hybrids do not rely solely on electric power. Thus, drivers do not have to worry about finding charging stations or having limited range.
