What is Toyota 48V Technology?

Published in Automotive Mild Hybrid 2 mins read

Toyota's 48V technology is a mild-hybrid system designed to enhance the performance, efficiency, and refinement of its vehicles, particularly those equipped with the 2.8-litre turbo-diesel engine. It represents a significant step towards electrification, offering a balance between traditional internal combustion engines and full hybrid or electric powertrains.

This innovative system, sometimes referred to as V-Active Technology in models like the new Toyota HiLux, is engineered to deliver a superior driving experience.

Key Components of Toyota 48V Technology

The 48-volt system comprises a synergistic combination of specific components that work together to capture and deploy energy efficiently:

Component Function
Motor Generator Acts as both an electric motor (assisting the engine) and a generator (recovering energy during deceleration).
48-Volt Battery A compact lithium-ion battery that stores energy captured by the motor generator.
DC/DC Converter Manages the power flow between the 48-volt system and the vehicle's standard 12-volt electrical system.

Benefits and Improvements

The integration of Toyota's 48V technology into vehicles like the HiLux with the 2.8-litre turbo-diesel engine brings a range of notable improvements:

  • Enhanced Driveability: Provides an immediate boost in responsiveness and smoother acceleration, especially from a standstill, leading to a more engaging driving experience.
  • Improved Performance: The motor generator offers supplemental power to the engine, contributing to better overall performance and acceleration.
  • Greater Fuel Efficiency: By assisting the engine and enabling features like engine stop-start during idling or coasting, the system helps reduce fuel consumption.
  • Reduced Noise, Vibration, and Harshness (NVH): The electric motor assistance allows the engine to operate more smoothly, leading to a quieter cabin and a more refined ride quality, particularly noticeable during engine restarts and low-speed driving.

This technology is a strategic move by Toyota to boost the capabilities of its popular models, offering a compelling blend of power, economy, and comfort.
