135VDC~260VDC High Integrated Wireless Cell Monitoring Battery Load Discharge Capacity Tester

135VDC~260VDC Battery Capacity Tester for Battery Online Monitoring 





 System FunctionAuto-inspection function: real-time collect each single cell voltage, batterypack's terminal voltage, charge and discharge current, ambient temperature, and positive and negative bus to ground voltage.Discharge function: have constant current discharging according to batterypack capacity, when a cell voltage is lower than the set lower limit value or reaches the set discharge time, AC power loss, etc, it will terminate discharging automatically.Battery internal resistance test function: adopt DC discharge method to test battery internal resistance.Auto-balancing function: automatically online adjust the floating charge voltage of each single cell, and maintain its voltage uniformity.AC inrush DC detection function: automatically monitor whether there is AC inrush DC system in real time.Parameter setting: the user can set the alarm parameters by himself, including the upper & lower limit of single cell voltage, the upper & lower limit of the whole battery pack voltage, the upper & lower limit of current (current=0), AC inrush threshold, etc.Alarm function: 1>Over limit of whole battery pack voltage (upper and lower limits); 2>Over limit of single cell voltage (upper and lower limits); 3>Current over limit; 4>AC inrush; 5>Over limit of voltage's average deviation value; 6>AC power loss; 7>Equipment itself fault; Use sound and light alarm, and automatically save alarm records (including alarm time, alarm contents, etc.), support power-down save, can be consulted any time.Communication function: the equipment with RJ45, RS485 and USB communication ports. It can communicate with remote server through network to realize remote network centralized monitoring, and export data through USB port.With multiple expandable I/O ports, which can be used for alarm output and other information collection and control.Equipped with computer management analysis and monitoring software. Monitor and manage each terminal equipment through LAN (Storage battery pack online monitoring system). It has excellent compatibility and expansibility .With remote maintenance function.

 System FeaturesThe system adopts modular architecture, and each component is independent and electrically isolated, which is convenient for system extension and maintenance.Rich functions: storage battery voltage, current and internal resistance detection; check and discharge; balanced maintenance; positive and negative bus to ground voltage detection; monitoring alarm for AC inrush DC and remote network centralized monitoring and management.Adopt high precision A/D converter chip and optimized circuit design, high data acquisition precision and fast acquisition speed.Each cell voltage acquisition module's front and back adopt isolation technology, with good insulation performance, high reliability and safety.Discharge protection: when having check discharge, it will automatically stop discharging when the single cell voltage is lower than the set value, reaching the set discharge time or capacity, and AC power loss.With network communication function and can directly connect to LAN and realize network remote monitoring.Automatically save alarm information and test data, support power-down save and U disk export.The host storage: voltage change+timing storage.
