Application: Dual-battery power management system and method capable of automatically determining battery type and performing charge-discharge protection (Patent ID: US20240204553A1)
The patent filed by Inventec Corp. describes a dual-battery power management system and method that can automatically determine battery types and provide charging and discharging protection. The system includes first and second battery modules, a bidirectional power converter, a voltage detection circuit, and a processing circuit. The processing circuit is designed to fully discharge the second battery module while charging the first battery module to determine the battery capacity of the second battery module. It then uses the first battery module to charge the second battery module based on a preset battery charging rate and detects the voltage of the second battery module to determine the battery type according to a comparison table. The system controls the charging and discharging of the second battery module based on the determined battery type.
The claims of the patent detail the specific functions and features of the dual-battery power management system. These include controlling the charging and discharging mechanisms based on the battery type, adjusting output voltage and current for safe charging and discharging, defining battery types such as lead-acid, lithium-ion, and lithium iron phosphate, and monitoring voltage drops to maintain battery capacity. The system also includes a method for determining battery types, obtaining safe charging and discharging information, and controlling the bidirectional power converter to ensure proper charging and discharging within safe voltage and current ranges. The predetermined battery charging rate is specified to range from 0.2 C to 0.3 C, and the system is designed to handle various battery types and charging scenarios effectively.
