specific Embodiment approach 1

[0025] Specific implementation mode 1. Combination figure 1 with figure 2 Describe this embodiment, the distributed wireless bus battery screening and testing system, using the distributed master-slave topology to divide the system into a processing and monitoring unit and an acquisition and testing unit; data is transmitted through a wireless local area network, and the network is constructed using ZigBee technology . The collection and testing unit is composed of several slave devices, each of which has no electrical connection, and is responsible for independently completing the task of screening and testing the single battery and feeding back the collected data. The processing and monitoring unit is composed of an industrial computer and a master device, and is responsible for sending task instructions to each slave device, receiving and processing battery parameters and data display collected by the slave devices.

[0026] The main device is composed of a wireless cont...

specific Embodiment approach 2

[0030] Embodiment 2. This embodiment is the test method of the distributed wireless bus battery screening and testing system described in Embodiment 1. The method is implemented by the following steps:

[0031] 1. Insert the master device into the USB interface of the industrial computer, the master device creates a wireless local area network through the wireless control module, and waits for N slave devices to join the network.

[0032] 2. Run the screening and testing host computer program on the industrial computer, and the program interface will display the current status of the wireless local area network and the status of the slave devices that have joined the network in real time. After the slave device is powered on, it will automatically join the wireless local area network created by the master device.

[0033] 2. After connecting the battery unit to be tested with the slave device, the slave device is ready to receive tasks. Taking the discharge characteristic cur...

Abstract

The invention discloses a screening and testing system for distributed type wireless bus batteries and a testing method and relates to the field of battery detection. By adoption of the screening andtesting system and the testing method, the problems that due to complex line connection in the existing battery detection system, the reliability, the expansibility and the flexibility of the system are reduced and the screening and testing efficiency is influenced and the like are solved. The screening and testing system is characterized in that a distributed type master-slave topological structure is adopted to divide the system into a processing and monitoring unit and an acquisition and testing unit; the processing and monitoring unit and the acquisition and testing unit transmit data by awireless local area network constructed by a ZigBee technology; the acquisition and testing unit comprises a plurality of slave devices which are respectively used for finishing screening and testingof single battery to be tested; the processing and monitoring unit is responsible for sending instructions to all the slave devices, receiving, processing, screening and testing data, acquired by allthe slave devices, of the single battery to be tested, and displaying the data; the slave devices for testing the single battery to be tested run independently without physical and electrical connection, and all the slave devices and a master device form the wireless local area network by the ZigBee technology so as to carry out data transmission.

Description

technical field [0001] The invention relates to the field of battery detection, in particular to a distributed wireless bus battery screening test system and a test method. Background technique [0002] Usually, in most applications, in order to meet the requirements of voltage and capacity, it is necessary to combine battery cells in series and parallel to form a battery pack. However, due to the difference in manufacturing characteristic parameters of the battery cells, it will affect its power in the battery pack during use. The consistency of performance reduces the overall performance of the battery pack. The battery screening test can obtain the characteristics of the single battery, and improve the consistency of the battery pack through group matching and other means. [0003] At present, most of the battery screening and testing systems are a whole cabinet equipment, which connects multiple battery cells to terminals for testing, and the equipment is physically and...
