A dual power control system for electric vehicles refers to a system that allows the vehicle to be operated using two different power sources or modes of propulsion. Typically, this system enables the vehicle to switch between an electric power mode and another power mode, such as a combustion engine or a hybrid powertrain. Here are two common types of dual power control systems for electric vehicles:

Plug-in Hybrid Electric Vehicle (PHEV) System:

A PHEV system combines an electric motor and a combustion engine. It allows the vehicle to operate in electric-only mode for shorter distances, relying solely on the electric motor and the energy stored in the battery. When the battery charge is depleted or additional power is needed, the combustion engine engages and provides propulsion to the vehicle. The system intelligently switches between electric mode and hybrid mode based on factors such as battery charge level, power demand, and driving conditions.

Range-Extended Electric Vehicle (REEV) System:

An REEV system is similar to a PHEV system but with a primary focus on electric propulsion. It includes an electric motor and a smaller combustion engine, typically used as a generator. The combustion engine doesn't directly drive the wheels but acts as an onboard generator to charge the battery and extend the vehicle's overall range. The electric motor remains the primary means of propulsion, with the combustion engine providing additional power when needed.

The dual power control system in these vehicles typically includes sophisticated control algorithms and sensors to manage power flow, optimize energy efficiency, and ensure seamless transitions between different power modes. The system may also incorporate regenerative braking, which converts kinetic energy into electrical energy and stores it in the battery for later use.

The purpose of these dual power control systems is to offer the benefits of electric propulsion, such as reduced emissions and improved fuel efficiency, while providing the flexibility and extended range associated with other power sources. These systems cater to drivers who may have limited access to charging infrastructure or require longer driving distances beyond the electric range.

It's important to note that specific implementations of dual power control systems may vary between different vehicle manufacturers and models, each with its own unique features and capabilities.
