Embodiment Construction

[0008] The technical scheme of the present invention is described in detail below in conjunction with accompanying drawing, in conjunction with figure 1 , a novel semi-automatic lithium battery protection board function analyzer, including a simulation center, an MCU, and a host computer. The host computer is connected to the simulation center in communication, and the host computer is connected to the MCU, and the MCU is connected to the simulation center in two-way communication. The analog center described above is mainly composed of high-precision resistors, low-impedance MOSFETs, high-precision digital programmable power supplies, and high-voltage-stabilized switching power supplies. The high-precision resistor controls the entire battery pack by dividing the voltage of the switching power supply, and simulates the change of a single cell in the entire battery pack by dividing the voltage of the digital programmable power supply. Throughout the system, high-precision ...

Abstract

The invention discloses a novel semi-automatic lithium battery protection panel function analyzer which comprises a simulation center, an MCU and an upper computer. The upper computer is in communication connection with the simulation center, the upper computer is in double-direction communication connection with the MCU, and the MCU is in double-direction communication connection with the simulation center. The simulation center mainly comprises a high-precision resistor, a low-impedance MOSFET, a high-precision digital programmable power supply and a high-stabilization-degree switch power supply. The function analyzer has the advantages of being capable of well adapting to practical production situations and being used, clear in function and capable of carrying out tests quickly and conveniently, and facilitating simple operations for workers.

Description

technical field [0001] The invention relates to the technical field of lithium batteries, in particular to a novel semi-automatic lithium battery protection board function analyzer. Background technique [0002] Since Sony successfully developed the first commercial lithium-ion battery in 1992, lithium batteries have been widely used in portable electronic products due to their high energy ratio, long life, high platform voltage, and environmental protection. In recent years, its market share in the field of power batteries has also increased year by year. Although lithium-ion batteries have many advantages over other secondary batteries, they are not resistant to overcharge and overdischarge, and require peripheral protection circuits to protect them, which is what we usually call protection boards. The quality of the protection board determines its ability to protect the lithium battery, so it is particularly important to detect it. The traditional protective boa...
