  • Product Introduction

ZCO-420 series battery monitoring and management system is used for real-time online monitoring and management of the operating parameters of the battery's single voltage, single internal resistance, current and ambient temperature. Avoid human interference caused by the use of hand-held equipment, and all tests are carried out automatically. Ensure that the battery is in the safest operating environment.

  • Product Parameters

ZCO-420-S data acquisition module is divided into two types, ZCO-420-S-12V and ZCO-420-S-2V. The battery system composed of 12V / 6V battery and 2V battery is tested and data acquisition respectively. Multiple ZCO-420-S can be connected through 485 interface to realize data acquisition of UPS system with different battery configuration.

  • Product Features

[Real online internal resistance measurement] The internal resistance test of ZCO-420 series battery monitoring and management system is completed automatically. There is no need to change the operating state of the battery pack. At the same time, in the process of internal resistance test, there is no need to discharge, which is a really safe internal resistance measurement method. [Modular structure design to meet various battery configurations] ZCO-420 series battery monitoring and management system adopts modular structure design. Each ZCO420-S module can connect up to 128 batteries in series. It can satisfy various battery system configurations through different module combinations. Internal resistance test method:
