Abstract: A master-slave type battery management system for accurate capacity gauge of battery packs is disclosed. It includes several battery management units linked to each other via a communication line. Each battery management unit is linked to a specified rechargeable battery set to manage the specified rechargeable battery set, detect a physical measurement data from the specified rechargeable battery set and calculates battery set capacity related value based on the physical measurement data. Each battery management unit has a unique battery ID. By assigning a battery management unit having a specified battery ID as a master battery management unit, the rest battery management units become slave battery management units. Each slave battery management unit sends the physical measurement data and battery set capacity related value to the master battery management unit via the communication line. The master battery management unit is in charge of calculating related values and transmitting them.

Abstract: A method of searching for full charge capacity of stacked battery cells in a rechargeable battery pack and a battery management system based on the method are disclosed. The method includes the steps of: predefining an end-of-discharge condition as a ratio of change of open-circuit cell voltage to change of state of charge; providing a full charge capacity for a rechargeable battery pack assembled of several stacked battery cells; charging the rechargeable battery pack until it is fully; discharging the rechargeable battery pack; measuring current values and open-circuit cell voltages periodically; processing coulomb counting based on the measured current values and zeroing a sum of coulomb counting values when a new discharging cycle begins; estimating state of charge during discharging periodically; calculating a running ratio; and updating the full charge capacity by the current sum of the coulomb counting values when the running ratio is equal to or greater than the end-of-discharge condition.

Abstract: An integrated circuit (IC) with a self-proofreading function includes a micro control unit (MCU) and a one-time programmable (OTP) memory connected with the MCU. The OTP memory includes an instruction memory region for storing instructions and a parameter memory region for storing standard parameters for proofreading. The MCU computes a measured result according to the standard parameters. The IC can operate without an external memory, therefore, the proofreading procedure using the IC is simplified, and the cost of the terminal product using the IC can be reduced.

Abstract: A method for programming a one-time programmable memory of an integrated circuit includes the following steps: writing an instruction set into the one-time programmable memory via a first programmable interface, running a programmable self-instruction of the instruction set, and writing a proofreading value of the integrated circuit into the one-time programmable memory via a second programmable interface. The present method takes full advantage of the one-time programmable memory. Manufacturers for manufacturing integrated circuits don't write various proofreading values corresponding to different applications. A producing efficiency can be increased, and a producing cost can be decreased. The present integrated circuit needs not to be communicated with an addition storing device, so the present integrated circuit has a simple construction, and the cost can be decreased. Since the present integrated circuit can write perform a proofreading self-instruction, the producing cost can be decreased.

Abstract: An integrated circuit (IC) includes a micro control unit (MCU), a one-time programmable (OTP) memory directly connected with the MCU, an electrical charge pump having an output port and an enable port connected to the MCU, and a switching circuit having a control port connected to the MCU, a first input port connected to the output port of the electrical charge pump, a second input port connected to a power source of the MCU, and an output port connected to the OTP memory to provide an operating voltage and a recording voltage for the OTP memory. Because the OTP memory can choose the operating voltage or the recording voltage, a measuring apparatus using this IC doesn't need an external power source to provide a VDD voltage being 5.8 volts. Therefore, a power consuming of the IC can be reduced.
