VEHICLE - A simplified explanation of the abstract
This abstract first appeared for US patent application 18530325 titled 'VEHICLE
The abstract describes a vehicle with a system that charges the battery by supplying direct-current power to a neutral point of the rotating electric machine. The control device predicts the traveling time to a charging place and restrains the rise in temperature of the charging group if certain conditions are met.
- The system includes a battery, a rotating electric machine, an electric power conversion device, a charging device, and a control device.
- During charging, direct-current power is supplied to the rotating electric machine's neutral point, which is then boosted and supplied to the battery.
- The control device predicts the traveling time to a charging place and restrains temperature rise in the charging group under specific conditions.
Potential Applications: - Electric vehicles - Hybrid vehicles - Energy-efficient transportation systems
Problems Solved: - Efficient battery charging - Temperature control during charging - Predictive maintenance for electric vehicle components
Benefits: - Extended battery life - Improved energy efficiency - Enhanced safety during charging
Commercial Applications: Title: "Smart Charging System for Electric Vehicles" This technology can be utilized in the automotive industry for the development of advanced electric and hybrid vehicles, catering to the growing demand for sustainable transportation solutions.
Questions about the technology: 1. How does the control device predict the traveling time to a charging place? The control device uses algorithms and data analysis to estimate the time required to reach a charging station based on various factors such as current speed, distance, and traffic conditions.
2. What are the specific conditions that need to be met for the control device to restrain the rise in temperature of the charging group? The conditions include higher temperatures of the battery, rotating electric machine, and electric power conversion device in the charging group compared to a set criterion temperature.
Original Abstract Submitted
A vehicle includes a battery, a rotating electric machine, an electric power conversion device, a charging device, and a control device. When the battery is charged, the charging device supplies direct-current power to a neutral point of the rotating electric machine, and the rotating electric machine and the electric power conversion device boost the direct-current power and supply the power to the battery. During traveling, the control device predicts a traveling time to a charging place, and executes a control that restrains rise in the temperature of a charging group in a case where the predicted traveling time is equal to or shorter than a criterion time and where a condition is satisfied, the condition being a condition that temperatures of the battery, the rotating electric machine and the electric power conversion device that are included in the charging group is higher than a criterion temperature.
