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's cooling system. 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 the charging process.
- The ambient temperature sensor measures the surrounding temperature and sends the data to the controller.
- The controller uses the information from the high-speed charging signal and ambient temperature sensor to monitor the refrigerant amount in the cooling system.
- If the monitoring result indicates an insufficient refrigerant amount, the controller adjusts the charging power to prevent the vehicle battery from overheating.
- By controlling the charging power based on the refrigerant amount, the system prevents situations where the battery cannot be properly cooled due to a lack of refrigerant.
Potential applications of this technology:
- Electric vehicle manufacturers can incorporate this system into their vehicles to ensure efficient cooling of the battery during high-speed charging.
- Charging station operators can use this system to prevent overheating of electric vehicle batteries and improve the overall charging experience for customers.
Problems solved by this technology:
- Insufficient refrigerant amount in the cooling system can lead to inadequate cooling of the electric vehicle battery during high-speed charging, potentially causing overheating and damage.
- By monitoring the refrigerant amount and adjusting the charging power accordingly, this system prevents such situations and ensures proper cooling of the battery.
Benefits of this technology:
- Improved battery cooling during high-speed charging, leading to increased battery lifespan and performance.
- Enhanced safety by preventing battery overheating and potential damage.
- Optimal charging experience for electric vehicle owners, with efficient and reliable cooling of the battery.
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.
