CHARGE & DISCHARGE TESTING

Let every megawatt of power and every
megawatt-hour of energy be verified against real operating curves

Under a 10–90% SOC window and 1.25 MW operating condition, verify capacity, efficiency, power response, rack consistency, thermal state, and time synchronization—and bind all results to one metering boundary and test-evidence chain.

Performance is not a nameplate number—it is a repeatable, reconcilable, and traceable closed-loop test.
