BHPian IloveVolvo07 recently shared this with other enthusiasts: At present, by restricting our domain of discussion to the Indian automotive industry, self-charging systems have tasted immense success in the C1 and D1 segments. The popularity of that system can be attributed to high efficiency values and reasonable pricing. However, it is important to iterate and improve upon the currently available power-train to ensure that hybrid power-trains can tap into a larger spectrum of the market. The current system could be improved by focusing on three major pillars of any power-train technology: efficiency, expenditure, and emissions. The new hybrid system being discussed here is called the “Dual-Battery Hybrid System.”System Overview: The power-train comprises an internal combustion engine that is connected to an electric generator to charge a dual-battery setup. The dual batteries are interchangeably responsible for either accepting charge from the generator or powering the electric motor. The role of the battery is determined by an algorithm that takes into consideration the state of charge (SOC).Efficiency: The engine of a self-charging hybrid is the source of energy for the vehicle, and it is responsible for charging the battery and powering the vehicle. The efficiency values could be substantially improved by ensuring that the engine runs at its rated RPM (the RPM at which an ICE achieves its maximum efficacy) throughout the vehicle’s period of operation. Please refer to the oversimplified graph attached below for easier understanding. Expenditure: The cost of such a system may be significantly brought down by using simpler and fewer components. The engine is always being run at its peak efficiency, it allows for a smaller-sized ICE. The power-train does not require a gearbox as the prime mover of the vehicle is an electric motor, and the engine is never required to power the wheels directly. The torque range of an ICE and electric power-train systems are vastly different, and the all-electric version eradicates the requirement of a transmission entirely. Here, the size of batteries can be reduced to a reasonable extent as one of the packs is always accepting charge from the generator, and at no stage does the system experience a deficit of stored energy as long as the vehicle is fueled accordingly.Emissions: The system has the potential to reduce the emission levels of a hybrid powertrain further. The improved efficiency figures allow the engine to run less intensively for the same magnitude of work done. The image above represents the circuit diagram of the aforementioned power-train. Overall, I would love to receive critical feedback from the experienced and enthusiastic Team-BHP community. Additional Information: The system discussed in this thread is patented (patent number: 530688) in India by Mr.Narsing Rao Surnilla. I have worked alongside him to reach this stage of theoretical development. Thank you for reading! Check out BHPian comments for more insights and information.
