The 66200 Series Multi-Channel Programmable Battery Simulator
Description
The 66200 series multi-channel programmable battery simulator with a host plugged into 16 battery simulator boards and 2 temperature simulator boards can meet the needs of BMS (Battery Management System) battery simulation and testing of PCM (Protection Circuit Module) battery protection boards. The simulator host is designed in a standard 19-inch 2U height format, suitable for system integration testing or desktop scenarios. Channels are isolated from each other, facilitating multi-channel series connection. It boasts ultra-fast transient response capabilities and utilizes unique variable output resistance technology. Its input-output characteristics can accurately simulate the real response of batteries. Additionally, it can monitor the power consumption of the devices under test (DUT) by measuring DC current.Main Features
- The simulator adopts a standard 19-inch 2U height design. The touchscreen interface allows for both desktop and integrated testing system setups in standard test cabinets. It supports series connection simulation of multi-cell battery packs across channels, and multiple simulators can be cascaded to form larger battery matrices. A single unit can simulate a battery module, and AFE testing can be completed on a single machine.
- The host can accommodate up to 16 cell emulation boards and 2 temperature simulation boards (providing 16 channels for cell emulation and 8 channels for NTC thermistor resistance simulation). Various boards with different specifications can be combined in the channels. Optional high-precision reference voltage source boards are available for current calibration. Channels are isolated from each other, ensuring testing and outputting do not interfere with each other.
- High-performance color touchscreen operation with a main screen displaying 18 channels.
- Using a four-wire connection method in which two lines are used for outputting voltage, and the other two directly measuring the voltage of the device under test. By measuring the lines through the SENSE terminal, the voltage drop caused by lead resistance between the battery simulator and the DUT can be eliminated.
- Real battery simulation, automatic switching between charging and discharging states, internal resistance simulation, suitable for conducting charge and discharge tests on various types of batteries. It can also simulate the charge and discharge characteristics of batteries to assist in other testing tasks. This instrument serves multiple purposes, streamline testing equipment, and optimizes testing processes.
- Its current feedback has a maximum resolution of 100nA, with current accuracy of 0.1%. It can provide the precision required to monitor leakage and idle currents in today's and future battery-powered products during sleep modes.
- The standard model comes with LAN and RS232 communication ports.

The 66200 series multi-channel programmable battery simulator is applicable in BMS testing. It is capable of dynamically simulating individual/cumulative voltage conditions or standard charge-discharge curves of batteries. It can simulate the battery pack voltage of series-connected battery modules, with each cell's voltage varying between 0-6V. This includes setting conditions such as Vcell Balance, OVP (Over Voltage Protection), UVP (Under Voltage Protection), reverse wake-up, etc.
The virtual battery receives commands from the computer host to adjust its output voltage independently, completing virtual charge and discharge tests of battery voltage. This is used to test the battery balancing function of BMS. The current for each cell can vary up to -3A to 3A, enabling detection of Vcell Balance function, with a set resolution of 1mA.
The simulated battery module can read back the voltage and current of each channel, allowing comparison with the test communication data of the BMS under test. This helps determine the accuracy of BMS voltage detection, overcharge detection, under-discharge detection, and the accuracy of individual cell voltage abnormality/recovery signal response. The unit is designed with modularization, allowing expansion by adding corresponding module units as needed.
