Higher integration and better functions

SAT-AG Stationary battery comprehensive tester is a kind of product introduced according to the market demand, which integrates the
three major functions.

Online monitoring for battery string

When the battery string is under the state of online discharge, uniform charge and floating charge, perform real-time online monitoring
for all cells.

Discharge function

Perform discharge of constant current taking advantage of intellectualized dummy load after the battery pack is removed from system,
set up the parameters,the tester could carry out discharge function automatically, when the string reaches the conditions to stop
discharging or manual final operation could stop discharge test.

Quick capacity test function

Under the state of offline state, it just takes 5 20 minutes to measure the actual capacity of all cells.

Powerful PC management software function

Create test report automatically. Zoom in and out the graphs

of voltage, inner resistance and capacity.

OXX Version testing equipment can connect to our SAT-AM Stationary battery data Logging Devices to quickly run the constant current
discharge, capacity and internal rsistance function.
