CHARGE CONTROL DEVICE FOR HYBRID ELECTRIC VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 20240174214 titled 'CHARGE CONTROL DEVICE FOR HYBRID ELECTRIC VEHICLE
Simplified Explanation
The patent application describes a system for managing the charge level of a battery in a vehicle by adjusting the engine rotational speed and controlling the negative torque of the electric motor to ensure the battery is maintained at a preset target charge level.
- The engine rotational speed is increased when the battery charge level decreases to a predetermined value, keeping the engine operating within a stable torque region.
- The electric motor is used to control the negative torque, allowing the battery to be brought back to the target charge level.
Potential Applications
This technology could be applied in electric vehicles, hybrid vehicles, and other battery-powered systems where efficient battery management is crucial.
Problems Solved
This technology addresses the issue of maintaining optimal battery charge levels in vehicles, ensuring that the battery is not depleted beyond a safe threshold.
Benefits
- Improved battery longevity - Enhanced vehicle performance - Increased energy efficiency
Potential Commercial Applications
- Automotive industry for electric and hybrid vehicles - Energy storage systems for renewable energy sources
Possible Prior Art
One potential prior art could be the use of regenerative braking systems in electric vehicles to recharge the battery while driving.
Unanswered Questions
How does this technology impact overall vehicle efficiency?
This technology can improve overall vehicle efficiency by optimizing battery charge levels, but the exact impact on efficiency metrics such as fuel consumption or energy usage needs further investigation.
What are the potential limitations of this system in extreme operating conditions?
It is important to consider how this system performs in extreme weather conditions, high-speed driving, or other challenging scenarios where battery management is critical. Further testing and analysis are needed to determine the limitations of this technology.
Original Abstract Submitted
when the remaining charge level of the battery decreases to a predetermined first determination value or less, the engine rotational speed increase control unit increases the target lower limit rotational speed of the engine or of the motor to the target lower limit rotational speed so that the operating point of the engine falls within a predetermined engine torque stable region. then, in a state where the operating point of the engine is within the engine torque stable region, the charge control unit controls the negative torque of the electric motor so that the actual charge level by the electric motor becomes a preset target charge level. the battery can thus be recovered from an insufficient charge level.
