Chroma 17010H 배터리 신뢰성 테스트 시스템은 고전류/고전력 성능 테스트를 위해 특별히 설계된 고정밀 충전 및 방전 테스트 장비입니다. 이 시스템은 대형 리튬 이온 배터리 셀(LIB 셀), 전기 이중층 커패시터(EDLC) 및 리튬 이온 커패시터(LIC)의 성능 평가, 수명 주기 테스트 및 제품 선택에 적합합니다.
The 17010H's energy recovery circuit architecture offers a marked improvement over traditional switching power supply equipment. It features high measurement accuracy and precision, high-speed current response, zero-crossover time for charge/discharge conversion, as well as multiple current ranges. These characteristics enhance the accuracy of battery cell capacity tests, improve performance parameter validation, and facilitate realistic dynamic current and power testing. In addition, Chroma 17010H features a powerful 30-second 200% pulse current output function. For instance, a unit with a single-channel continuous current of 300A can produce a 30-second 600A pulse current. This provides a highly cost-effective and space-saving solution for applications such as power capability and DC internal resistance testing, which require short but high-rate test currents.
고전류 수명 주기 테스트는 장비의 에너지 변환 효율성 테스트의 중요성을 강조합니다. 그 이점으로는 전력 수요 감소 뿐만 아니라 열 생산의 큰 감소도 있습니다. 제어 회로는 상대적으로 낮은 온도에서 작동하여 효과적으로 열 드리프트를 억제하고 부품의 수명 주기를 연장합니다. 이러한 방식으로 17010H는 정확하고 안정적인 테스트 성능을 달성합니다. 선형 회로 제품에 비해 에너지 변환 효율이 높고 전력 밀도가 높으며, 실험실의 전력 분배 요구 사항이 감소하고, 운영 전력 및 공조 비용이 절감되며, 공간 활용도가 향상됩니다.
Designed with the diversity of battery cell products and experiments in mind, Chroma 17010H features a channel parallel function with a continuous current up to 2400A and a pulse current up to 4800A. The performance of paralleled channels remains unchanged, with the exact same precision specifications and no response delay, significantly enhancing the equipment's applicability.
안전성과 관련하여 각 채널에는 레벨 2 V 보호 기능이 추가로 장착되어 있으며, 단일 부품이 고장 날 경우 독립적인 측정 루프가 배터리 과전압을 방지하여 테스트 안전성을 향상시킵니다. 또한 시스템의 제품 유지보수 설계가 개선되었습니다. 회로 장치는 모듈화 되어 있으며, 개별적으로 빠르게 조립하고 분해할 수 있어 유지보수 및 채널 백업이 편리합니다.
테스트 표준을 충족하는 정확한 출력 기능
Run power capability tests and driving simulations to test compliance of vehicle batteries with international standards. Test parameters for high-rate current and power are based on battery operating conditions (such as BEV, PHEV and HEV) with an output time of 30S, which makes purchasing full-power equipment unnecessary. Chroma 17010H not only provides up to 200% rated pulse current and power output capability, but can also effectively save equipment costs and space.
Chroma 17010H는 방전 중에 방출된 DC 전기 에너지를 AC로 회생하여 AC 전원 계통으로 다시 공급하여 열 발생을 크게 줄이고, 탄소 배출량이 적은 친환경 에너지 제조를 실현하며, 전력 분배 요구 사항을 줄이고, 운영 전력 및 공조 비용을 절감합니다.

정확도는 서로 다른 채널 데이터를 비교하는 데 중요한 요소입니다
Battery products often require multi-channel experiments for comparative analysis. High accuracy ensures that the data's baseline deviation between different channels is minimal, making comparisons more objective.
높은 정밀도는 데이터 분석 효율성 향상
배터리 내부는 복잡한 전기 화학 구조이며, 그 특성은 전류, 온도, SOC, SOH 및 기타 실험 조건에 의해 변경됩니다. 초기 변경은 미묘하며 장비의 측정 안정성에 쉽게 영향을 받습니다. 높은 정밀도는 측정 재현성을 보장하고 측정으로 인한 데이터 누락을 감소시키며, 이는 테스트 데이터 해석에 매우 유용합니다.
