Intelligent battery cell system with integrated monitoring and switches
The granted patent (Publication Number: US11973199B2) describes a system comprising modular battery cell devices with internal circuits that operate in defined operation modes to provide alternating current (AC) and direct current (DC) energy supplies simultaneously. These modular battery cell devices are connected to switches that link them to AC and DC terminals. Additionally, a control unit is included to manage the switches, enabling the concurrent provision of AC and DC energy supplies.
Furthermore, the system includes a control unit that facilitates the provision of AC energy supply at the AC terminal while receiving a charging DC energy supply at the DC terminal. The internal circuits of the modular battery cell devices are designed to operate in various defined operation modes, including off mode, bypass mode, positive mode, and negative mode, each corresponding to specific electric potential values at the battery cell poles. The internal circuits also feature transformers that deliver a defined DC energy supply at the battery cell poles while ensuring electrical insulation between the AC and DC energy supplies. Overall, this patented system offers a versatile and efficient solution for providing both AC and DC energy supplies simultaneously, with the ability to manage different operation modes effectively.
