Title: Myung-Sang Lee: Battery Protection Inventions

Introduction

Myung-Sang Lee is an inventor based in Yongin, South Korea. His work includes battery protection technologies, and he is associated with Samsung SDI Co., Inc. Lee is credited with 2 patents.

Latest Patents

Lee’s listed patents focus on controlling charging and protecting batteries from potentially harmful electrical conditions.

The patent titled “Battery Protective Circuit” describes a system with a battery controller, a charging control transistor, and a protection circuit. The protection circuit monitors voltage at a terminal connected to a load. When it detects voltage at or above a specified threshold, it signals the charging control transistor to turn off, regardless of the charging control voltage. This design provides an additional means of interrupting the charging connection when a potentially unsafe voltage is detected.

“Battery Protection Circuit” describes a circuit that uses a voltage source, resistors, a charging controller, a charging transistor, and a current-to-voltage converter. The converter controls the electrical connection between the voltage source and the transistor’s gate according to the charging control current. This arrangement supports control of the charging transistor as part of the battery protection system.
