REFRIGERANT AMOUNT MONITORING AND CHARGING CONTROL SYSTEM FOR ELECTRIC VEHICLE AND METHOD THEREOF - A simplified explanation of the abstract
This abstract first appeared for US patent application 17898197 titled 'REFRIGERANT AMOUNT MONITORING AND CHARGING CONTROL SYSTEM FOR ELECTRIC VEHICLE AND METHOD THEREOF
Simplified Explanation
The patent application describes a system and method for monitoring and controlling the refrigerant amount in an electric vehicle during charging. The system includes a controller, a battery management module, a high-speed charging gun, an ambient temperature sensor, and a chiller with an electronic expansion valve and an evaporator.
- The high-speed charging gun generates a high-speed charging signal and sends it to the controller during charging.
- The ambient temperature sensor measures the ambient temperature and sends it to the controller.
- The controller uses the information from the high-speed charging signal and the ambient temperature sensor to monitor the refrigerant amount.
- If the refrigerant amount is insufficient, the controller adjusts the charging power to prevent the vehicle battery from overheating.
Potential applications of this technology:
- Electric vehicle manufacturers can incorporate this system into their vehicles to ensure proper cooling of the battery during high-speed charging.
- Charging station operators can use this system to prevent battery overheating and improve the charging efficiency of electric vehicles.
Problems solved by this technology:
- Prevents situations where the vehicle battery cannot be cooled due to insufficient refrigerant, reducing the risk of battery damage or failure.
- Ensures that the battery remains within the optimal temperature range during high-speed charging, improving overall battery performance and lifespan.
Benefits of this technology:
- Improved safety and reliability of electric vehicles by preventing battery overheating.
- Enhanced charging efficiency and reduced charging time for electric vehicles.
- Extended battery lifespan and improved overall performance.
Original Abstract Submitted
A refrigerant amount monitoring and charging control system for an electric vehicle and a method thereof include: a controller; a battery management module electrically connected to the controller; a high-speed charging gun connected to the vehicle when the vehicle is charged and configured to generate a high-speed charging signal during performing high-speed charging and to send the high-speed charging signal to the controller; an ambient temperature sensor electrically connected to the controller and configured to obtain an ambient temperature and to send the obtained ambient temperature to the controller; and a chiller including an electronic expansion valve and an evaporator. A situation where a vehicle battery is unable to be cooled by a refrigerant due to an insufficient refrigerant amount may be prevented by controlling charging power based on a monitoring result of a current refrigerant amount.
