Embodiment Construction

[0028] Such as figure 2 shown. Its capacity division steps are:

[0029] (1) First, set the volume division section on the host computer (PC). The volume division section can be divided into multiple sections according to the needs. In this embodiment, three volume division sections are set: 1000mah-1100mah, 1100mah-1200mah, 1200mah-1300mah.

[0030] (2) At the beginning of the capacity division, through the RS485 interface communication, the upper computer sends a segment of 1000mah-1100mah to the lower computer of the capacity division device loaded with the battery; after receiving the command, the lower computer first collects and stores the battery data of the entire device Current and voltage values.

[0031] (3) Then light up the indicators of the batteries whose capacity is in this section in the first group of m batteries, and collect the voltage and current values ​​of the m batteries in this group in real time, and the voltage and current collected in step (2) ...

Abstract

Condition indication for different capacities of batteries indicates from first group to last group step by step. Procedure for separating different capacities tracks online states of being tested batteries in real time. The method gives audible and visual alarm for cases: miss fetched batteries or wrong fetched batteries. The method guarantees procedure for separating different capacities of batteries correctly and safely. The invention is suitable to batteries of nickel-hydrogen, nickel-cadmium, lithium cell in liquid state and lithium cell in polymer.

Description

technical field [0001] The invention relates to a secondary battery capacity classification method for real-time tracking and alarming for the capacity sorting process of nickel hydrogen, nickel cadmium, lithium ion batteries and polymer lithium batteries on a battery formation and detection and sorting system. Background technique [0002] In the battery formation and testing system, the capacity sorting technology is one of the key technologies related to the performance and reliability of the entire system, directly related to the accuracy of the capacity and the quality of the delivered battery. At present, the commonly used methods of manually dividing the battery capacity include the method of synchronous single-color lamp capacity division and the method of synchronous three-color light capacity division. [0003] The arrangement structure of the batteries to be tested in the battery testing cabinet is as follows: figure 1 As shown, the equipment is composed of n gro...
