Abstract

The invention discloses a lithium battery equipment parameter acquisition circuit and system. The system comprises a measuring circuit, a switching circuit, a reading circuit and a main control circuit. The measuring circuit is connected with at least two lithium batteries, measures the working current and the working voltage of each lithium battery one by one, and outputs corresponding voltage measuring values and current measuring values to the switching circuit; the switching circuit is provided with at least two voltage measuring channels and two current measuring channels, sequentially gates the voltage measuring channels and the current measuring channels to drive the measuring circuit to work, and transmits each voltage measuring value and each current measuring value to the readingcircuit; and the voltage measuring values and the current measuring values are displayed by the reading circuit and fed back to the main control circuit, and the main control circuit stores the voltage measuring values and the current measuring values. According to the lithium battery equipment parameter acquisition circuit and system, the voltage measuring values and current measuring values ofa plurality of lithium batteries can be measured at a time, the operation is convenient and fast, the detection efficiency is high, the consumed time is short, and the problem of high error rate caused by multiple times of manual detection is avoided.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, and in particular relates to a lithium battery equipment parameter acquisition circuit and system. Background technique [0002] Usually, a battery sorting cabinet is used to divide the capacity of multiple lithium batteries, that is, to perform performance screening on multiple lithium batteries. Among them, operating current and operating voltage are two important performance parameters of lithium batteries. At present, the traditional measurement method is to connect the measurement fixture corresponding to each lithium battery in the battery sub-container with the current gear / voltage gear of the multimeter through the measurer, and then perform single-point measurement to collect the working current and voltage of each lithium battery. Operating voltage to analyze the performance of the battery separation cabinet and to calibrate the battery separation cabinet. Assuming that each ...
