CHARGE CONTROL DEVICE FOR HYBRID ELECTRIC VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18467067 titled 'CHARGE CONTROL DEVICE FOR HYBRID ELECTRIC VEHICLE
Simplified Explanation
The patent application describes a system that manages 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.
- Engine rotational speed is increased when battery charge level is low to keep the engine operating within a stable torque region.
- Electric motor's negative torque is controlled to bring the battery charge level to the target level when the engine is within the stable torque region.
Potential Applications
This technology can be applied in electric vehicles, hybrid vehicles, and other battery-powered vehicles to optimize battery charge levels and improve overall efficiency.
Problems Solved
1. Preventing the battery from reaching critically low charge levels. 2. Ensuring the engine operates within a stable torque region for optimal performance.
Benefits
1. Improved battery management for extended battery life. 2. Enhanced vehicle efficiency and performance. 3. Reduced risk of battery failure due to low charge levels.
Potential Commercial Applications
"Optimizing Battery Charge Levels in Electric Vehicles: A Game-Changer for Efficiency and Performance"
Possible Prior Art
There may be prior art related to battery management systems in vehicles, but specific examples are not provided in the abstract.
Unanswered Questions
How does this technology impact the overall lifespan of the battery in the vehicle?
The technology is designed to optimize battery charge levels, which can potentially extend the lifespan of the battery. However, the exact impact on battery lifespan would depend on various factors such as usage patterns, environmental conditions, and maintenance practices.
What are the potential cost implications of implementing this technology in vehicles?
The cost implications of implementing this technology would depend on factors such as the complexity of the system, the type of vehicles it is installed in, and the scale of production. Further research and analysis would be needed to determine the specific cost implications for vehicle manufacturers and consumers.
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.
