The e-charger system is an innovative hybrid bolt-on solution created to improve vehicle performance, decrease fuel consumption, and minimize emissions. By integrating electric motor technology with conventional internal combustion engines, this system offers drivers a sustainable and economical method to enhance their vehicle's efficiency. It is particularly well-suited for hybrid vehicle conversions, making it an intelligent option for individuals seeking to switch to more eco-friendly transportation without compromising on power.
Technology Overview
Stored Energy and Regenerative Braking
The heart of the e-charger system is its ability to harness and store energy. This energy is captured during deceleration or braking, known as regenerative braking. The system stores this energy in a battery pack, which is then used to assist the internal combustion engine when additional power is needed. This process not only improves fuel efficiency by up to 25% but also reduces strain on the engine, resulting in smoother and more responsive acceleration.
System Components
Key Components of the E-Charger System
The e-charger system consists of several key components:
- Electric Motor: A 50 kW AC motor connected to the engine via a Gilmer belt drive. This motor provides additional torque when required, improving vehicle performance without increasing fuel consumption.
- Battery Pack: A 10 kW lithium-ion phosphate battery pack stores the energy captured during regenerative braking. This battery can be recharged using standard EV charging stations.
- Controller: The system's controller manages the power distribution between the motor and the battery pack, ensuring the vehicle operates efficiently under various conditions.
