It has voltage and current measurement and monitoring capabilities, providing 0~5V voltage regulation and 0~5A bidirectional current function per channel with simulation of voltage variation for 480 battery packs (2000V/4.2V) connected in series. The equipped output voltage control is convenient in testing upper and lower limits of battery operating range. It supports active and passive balancing circuit tests in 0~5A and 0~500mA two current ranges with measurement accuracy up to 0.02%F.S. For 0~5A range (power increase when paralleled), the accuracy is up to ±1mA with resolution up to 100uA that can meet the active balance design circuit test requirements. For 0~500mA range, the accuracy is ±100uA (0.02%F.S.) with resolution up to 10uA that can meet the passive balance design circuit test requirements. It is suitable for BMS circuit boards for measuring battery cell current consumption.

Significantly Reduce BMS Verification Costs

Certainly, the battery management system can also be used to verify the battery cell; however, it cannot maintain the same characteristics for repeated tests due to the influence of temperature, charging and discharging speeds, aging degree, and efficiency, etc. Moreover, setting up too many battery cells in the laboratory could raise safety concerns. In the past, the engineers connected several DC power supplies in series on their desk to test the cell supervision circuit (CSC) by manually adjusting the voltage and parameters, which took time and space, and the functions can be tested were limited. Using the Chroma 87001 Cell Simulator for testing became the better solution.

High Voltage Grid Simulator Adds PV Inverter’s HVRT Test Function

As photovoltaic industry policies continue its growing support for distributed solar power systems, commercial power generation equipment demands for 20kVA-100kVA inverters increase as well. With the development of grid-connected high-voltage 600Vac-800Vac (VLL) systems to reduce cost and increase power generation efficiency, an important challenge to manufacturers is the inverter’s stability in high-voltage grid connections. The newest high-voltage 1385Vac (VLL)/120kVA regenerative grid simulator released by Chroma meets the specifications for inverter quality verification and grid performance tests, such as LVRT, HVRT, harmonics, waveform distortion, 3-phase unbalance, voltage dips, short interruptions, and voltage change immunity tests.

mf00001048-01-en

61800_ac_load_4_tc

The latest UL1741 SA specification for inverter design must be able to run under HVRT test without off-line operation. In addition, it must have the capability to continuously adjust the power and infuse reactive current into the power system during high voltage ride through. So, when the inverter is designed for a normal rated voltage of 690Vac (VLL), it must be tested for rated grid voltage (over 897VLL) which is raised 1.3, 1.2, or 1.1 times respectively as it has to run uninterruptedly at dozens of test points during voltage rise and recovery. Moreover, it has to respond normally and issue a proportioned capacitive reactive current according to the standard during HVRT, which can effectively stabilized the grid voltage and ensure the demand for the quality of electricity.

Chroma’s high-voltage power grid simulator can output voltage up to 1385VLL (800VLN) without using a step up transformer. Besides up to 1.5V/us output voltage transient capability, it has flexible, cost-effective and space-saving features. For example, when testing an inverter below 50kVA, it can be used as two 60kVA power grid simulators; and if high power and high voltage 60-100kVA inverters are required for testing, two 60kVA power grid simulators can be connected in series for up to 1385VLL (800VLN).
