N8330 Series Ultra-high Accuracy Multi-channel Battery Simulator

Product Introduction
N8330 is a programmable battery simulator with low-power, multi-channel and high-accuracy. N8330 standalone supports up to 24 channels. Each channel is isolated. Users can set voltage & current for each channel on application software, which is easy to use and can meet the needs of multi-channel, multi-parameter and complex test environments. N8330 application software supports multi-channel batch operation. Data and graphs for each channel can be displayed. At the same time, data analysis and report functions are supported.

Ultra-high integration, single device with up to 24 channels
N8330 series adopts a standard 19-inch 2U size, with up to 24 channels in a single device. Each channel is isolated. One
Device can support 24-station test simultaneously, which greatly reduces the instruments used and improves test efficiency.

Ultra-high accuracy, supporting static power consumption and protection Parameter test
N8330 series is with high accuracy and resolution. the voltage resolution is as low as 50μV, and current resolution as low as 0.1μA. in standby mode, there is still μA-level current existing in electronic component. this condition requires the test instrument with current resolution of at least 1μA. Meanwhile, the protection parameters test of charging board also has extremely high demand on the test instrument accuracy. for example, the overcharge protection test requires to emulate voltage accuracy of the battery cell as low as mV-level.

Application -BMS Test
System Introduction
BMS (battery management system) is a device used to conduct safety monitoring and effective management of battery packs, and improve battery service efficiency. for electric vehicles, BMS can effectively control the charging and discharging of the battery pack, which can increase the endurance mileage, extend the service life, reduce the operating cost, and ensure the safety and reliability of power battery pack. BMS has become one of the essential core components of electric vehicles. In order to ensure the proper operation, it is necessary to test BMS comprehensively.

System Architecture
NGI BMS test platform adopts the modular design. It consists of high-accuracy battery simulator, temperature simulation unit, charge & discharge current simulation unit, high voltage power supply, IO detection unit, insulation detection unit, BMS signal and switch detection unit, CAN communication unit, software control system, etc. the system can provide customization on Li-on battery strings according to customers' needs and generate data reports. the system is highly integrated, convenient and efficient, supporting expansion and upgrade.
