Chroma's 17020E is a high precision system specifically designed for secondary battery module and pack testing. Highly accurate sourcing and measurements ensure that the test quality is suitable for performing repetitive and reliable tests crucial for battery modules/ packs, incoming and outgoing inspections, as well as performance, production, and qualification testing.
Three safety features are designed for battery testing: software for DUT communication protection, firmware for over voltage and over current protection, and multiple hardware protection circuits to ensure test procedures are performed safely.
The Chroma 17020E system is equipped with 2/4 independent channels to support dedicated charge/discharge tests on multiple battery modules/packs, each with discrete test characteristics to achieve a high utilization rate of the equipment.
The Chroma 17020E system has flexible programming functions and may be operated with Chroma's powerful "Battery Pro" software. The software can create cycling tests that range from basic charge or discharge to complex drive cycle testing for individual channels or channel groups. In the unlikely event of power or computer communication loss, the data is securely stored in the system's non-volatile memory, protecting against potential data loss and allowing for seamless continuation after restart.
The Chroma 17020E, with its high precision output and measurement specifications, ensures consistent test quality. A seamless transition function between charge and discharge allows programming a dynamic driving curve that can simulate the actual use of the battery pack on an electric vehicle.
The Chroma 17020E has a regenerative energy feature that recycles the electrical energy sourced by a battery module during discharge either back into the channels in the system that are performing a charging test or to the utility mains.
