ENERGY STORAGE SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 17555223 titled 'ENERGY STORAGE SYSTEM
Simplified Explanation
The energy storage system described in this patent application consists of a battery and a battery management system. The battery stores electrical energy in the form of direct current and can also output the stored energy. The battery management system controls the battery and includes various components.
- Sensing unit: This unit comprises multiple sensors that measure the voltage, current, and temperature of the battery.
- Memory: The system has a memory that stores two important parameters. One is the charge/discharge cycle count, which increases each time a charge or discharge cycle is executed. The other parameter is the under voltage protection level, which is a reference value that protects the battery from discharging below a certain voltage.
- Microcomputer unit: This unit is responsible for increasing the under voltage protection level when the charge/discharge cycle count reaches a specific number of times.
Potential applications of this technology:
- Renewable energy systems: The energy storage system can be used in conjunction with renewable energy sources like solar or wind power to store excess energy and provide a stable power supply.
- Electric vehicles: The system can be utilized in electric vehicles to store and manage the energy required for propulsion.
- Grid stabilization: By storing excess energy during low demand periods and releasing it during peak demand, the system can help stabilize the electrical grid.
Problems solved by this technology:
- Battery protection: The under voltage protection level ensures that the battery is not discharged below a certain voltage, preventing damage and extending its lifespan.
- Efficient energy management: The battery management system optimizes the charge/discharge cycles based on the cycle count, ensuring efficient utilization of the battery's capacity.
Benefits of this technology:
- Extended battery lifespan: By implementing under voltage protection, the system prevents excessive discharge and extends the battery's overall lifespan.
- Improved energy efficiency: The battery management system optimizes the charge/discharge cycles, maximizing the energy utilization and efficiency of the system.
- Enhanced safety: The sensing unit and battery management system monitor the battery's voltage, current, and temperature, ensuring safe operation and preventing potential hazards.
