Intelligent parameter sensor for battery

Device Overview
The intelligent parameter sensor for batteries is the first module in China that measures the internal resistance of batteries using a small DC discharge method based on individual batteries. It can also accurately measure the voltage and temperature of batteries simultaneously. It is mainly developed for online monitoring of valve regulated sealed lead-acid batteries, lithium batteries, gel or fixed batteries. The sensor is equipped with a communication interface and communicates through a dedicated communication bus and proprietary protocol. It can be widely used in fields such as power, military, aviation, railway, fire protection, and electric vehicles, and is the preferred device for "condition based maintenance" of batteries.

Model Description

Technical Features
1. Small size (80 * 49 * 24mm);
2. Low current DC discharge technology;
3. The accuracy of internal resistance measurement data is high, and it can be compared with the Cellcord Alber CLC-200 from Alber and the CTU-6000 from Midtronics for measurement of the same battery.
4. Good measurement consistency is an important technical feature that distinguishes the AC injection method.
5. High measurement accuracy.
6. Temperature measurement takes samples from the battery terminals, providing a more objective reflection of the temperature inside the battery.
7. Communication supports cascading communication, suitable for battery pack measurement.
8. Strong anti-interference ability.
