Latest Patent Applications

Chuanjun Liu has submitted several notable patent applications. One of his latest inventions is a voltage balancing system designed for controlling the voltage of battery cells. This system includes a high-side analog front end (AFE) connected to a first set of battery cells and a low-side AFE connected to a second set of battery cells. A microcontroller facilitates communication between the high-side and low-side AFEs, while a communication isolating module interconnects them. Additionally, a balancing module is included to equalize the voltages output by both AFEs, effectively reducing the voltage difference between the two sets of battery cells.

Another significant application is for a battery charging circuit, battery pack, and battery pack charging system. This circuit features a first control switch, a switch control unit, and a power supply unit. The first control switch, which is an NMOS transistor with a body diode, is strategically placed between the charging terminals and the battery pack electrodes. The switch control unit manages the on-off state of the first control switch by sampling the voltage between its source and drain. The power supply unit provides necessary power to the switch control unit.

Conclusion

Chuanjun Liu is making strides in the field of battery technology through his innovative patent applications. His contributions may lead to significant advancements in energy storage solutions.
