Embodiment 1
[0052] Combining the above-mentioned inventive ideas of the technical solution of the present invention, an on-line monitoring system for storage batteries, such as figure 1 and image 3 As shown, it includes: battery detection unit 100, current sampling unit 200, centralized monitoring unit 300, on-site display unit 400, data export unit 500, host computer monitoring unit 600, networking routing unit 700 and equipment charge absorption unit 800.
[0053] The battery detection unit 100 can adopt the battery monitoring module in the prior art. The battery detection unit 100 is connected in parallel with the storage battery and connected with the centralized monitoring unit 300 for electrical signals, and is used to collect the voltage, temperature and internal resistance of each storage battery in the storage battery pack. A detection signal is generated and sent to the centralized monitoring unit 300 .
[0054] The current sampling unit 200 adopts a current sensor connected t...
Embodiment 2
[0063] Combining the above-mentioned inventive idea of the technical solution of the present invention, a battery online monitoring method, such as Figure 5 shown, including the following steps:
[0064] Step S1: Collect the voltage, temperature and internal resistance of each battery in real time.
[0065] Step S2: collecting the charging current and discharging current of the battery pack.
[0066] Step S3: Transmitting the above-mentioned voltage, temperature, internal resistance, charging current and discharging current to the centralized monitoring unit 300 through the RS485 bus.
[0067] Step S4: The centralized monitoring unit 300 calculates the partial internal resistance of each battery and the total internal resistance of the battery pack by using the setting calculation method of the AC injection method.
[0068] Step S5: The centralized monitoring unit 300 determines the battery status data of the battery according to the internal resistance of each battery an...

Abstract
The invention discloses a storage battery online monitoring system and a method thereof. The system comprises a battery detection unit, which is connected to the storage battery in parallel to generate and send out a detection signal outwards; a current sampling unit, which is electrically connected to the storage battery set, and generates and sends outwardly a sampling signal; a centralized monitoring unit, which is in electric signal connection with the battery detection unit and the current sampling unit, and is used for determining battery state data of the storage battery and sending outa detection signal, a sampling signal and battery state data outwards; a field display unit, a data export unit and an upper computer monitoring unit, wherein the field display unit, the data exportunit and the upper computer monitoring unit are electrically connected with the centralized monitoring unit; a group network routing unit, which is in electric signal connection with the centralized monitoring unit and the remote monitoring network. The centralized monitoring unit sends a battery state data network to the remote monitoring network, the monitoring personnel of the remote monitoringcenter can obtain the battery state data through the remote monitoring network, so that remote monitoring of the storage battery is realized; manual inspection staff do not need to be arranged for manual inspection.
Description
technical field [0001] The invention relates to the technical field of storage battery monitoring, and more specifically, it relates to an online storage battery monitoring system and a method thereof. Background technique [0002] As an important part of the power system, the backup power system composed of batteries and battery monitoring systems plays a key role in storing electric energy, coping with power grid abnormalities and special working conditions, and maintaining the normal operation of the system. It is the last line in the field of high reliability power guarantee. line of defense. [0003] The battery monitoring system in the prior art can only detect the battery in real time offline. The battery monitoring system monitors, displays and records the battery pack voltage, charge and discharge current, each cell voltage, and the internal resistance of the cell during operation. It can configure temperature, The connection resistance between batteries and the co...
