I. System Overview

The 1000V200A series power battery performance testing system is an independently developed, high-precision AC/DC power processing system with bidirectional single-channel and multi-channel capabilities, controlled by a computer-based remote monitoring and processing platform. Utilizing the bidirectional nature of electrical infrastructure (capable of both transmitting and receiving electrical energy), the system meets the requirements for unidirectional and bidirectional load power transmission, enabling precise grid-fed control of load energy. The feeding process involves no power consumption by resistive loads, significantly reducing energy losses associated with traditional resistive discharge methods. This product is suitable for electrical performance testing of various battery types—including lithium-ion batteries, lead-acid batteries, and special liquid batteries—for applications such as capacity testing, cycle life evaluation, operational condition simulation, and overcharge/over-discharge tolerance testing. It also supports aging tests for electronic loads, including charger aging assessments.
