Product Components
BattLink
One BattLink can monitor the voltage, internal resistance and negative pole temperature of a single battery to provide continuous 24/7 monitoring of your battery infrastructure.
SensorLink
One module with an additional CT per battery string will intelligently analyze thermal runaway trends and effectively produce alarms for battery thermal runaway.
CurrentLink
One module with an additional CT per battery string will monitor the charge/discharge current and ambient temperature of a string.
Nexus
It can manage up to six groups of batteries, each group has a maximum of 300, and the total number is up to 960, with display and buttons.
Battery Health Indicators
The CurrentLink module monitors a variety of battery health indicators of a given battery string and reports back to the Nexus module. When combined with the other modules of the battery monitoring system, it ensures uptime with 24/7 monitoring of batteries in all applications.
