Description

Chroma 87001 Battery Cell Simulator is a highprecision,programmable, and bidirectionalDC power source with both voltage sourceand current source functions. In addition, themodel can be used as a multi-channel DCpower supply or an electronic load as well. Asingle simulator has 16 channels and each ofthem can set voltage and current respectivelyvia Chroma software.

The Chroma 87001 Battery Cell Simulatorcan be used in place of lithium-ion batteries to provide a reliable and safe testing environment . The equipped battery management system (BMS) and its subsystemscan test the battery cells used in electricvehicles and energy storage batteries, etc.

APPLICATION ARCHITECTURE DIAGRAM (Master/lave Architected Battery Management System)

The Chroma 87001 Battery Cell Simulator can be applied to high-voltage battery cell isolation units to simulate a variety of battery cellstrings scenarios. With bidirectional voltage and current source function, it can simultaneously simulate the battery cells connected inseries and the loading of external power devices to UUT. The architecture diagram shown below is an example of an integrated battery cellsimulator test system that provides a battery management unit (BMU) with subsystem Cell Supervising Circuit (CSC).

BATTERY CELL STATUS IN PARALLEL AND SERIAL OPERATION MODE

When multiple battery cells are required, the battery cell simulators can be connected in series for use. The simulator supports both serialand separate channel parallel connection modes that can simulate the battery cell status up to 480 cells. The parallel function with automaticcurrent sharing design makes the operation quick and easy allowing for greater simplicity to the user’s operating procedure. The 87001 isequipped with an Ethernet standard interface that can be used for remote control and other automated test applications.

PRECISION VOLTAGE/CURRENT MEASUREMENT

The Chroma 87001 Battery Cell Simulator has voltage source and bidirectional current source modes with a built-in 16-bit high-precision A/Dconverter. The voltage measurement accuracy is up to ±1mV (0.02%FS) with resolution up to 0.1mV.

For the market trend of active and passive balance design, the current measurement is divided into 0~5.2A/0~520mA two ranges with0.02%FS accuracy. For 0~5A (power increased in parallel connection) range, the accuracy is ± 1mA, which meets most of the industry’srequirements for testing the actively balancing designed circuits with a current measurement resolution up to 100uA.

For 0~500mA range, the accuracy is ±100uA (0.02%F.S.), which can meet most of the industry’s passive balance designs, and themeasurement resolution is up to 10uA. In addition to the passive balance for current measurement, it can also be used for cell supervisingcircuit to measure the current consumption of each battery cell (> 10mA for general consumption).

PROGRAMMING SEQUENCE AND APPLICATION

The battery cell simulator has 16 channels that can set the voltage and current limit respectively; programthe rise and fall of output voltage, and synchronize the start-up between channels via software. When thelow output noise features presents the DC characteristics of a battery cell without any ripples during dynamicload changes, it can quickly provide a steady DC output. Meanwhile, it reduces the surge voltage causedby the load change that could damage the UUT. For non-static products or test applications, it can supply astable DC voltage source in time.

The Chroma 87001 Battery Cell Simulator provides a high-speed, programmable, dynamic, and bidirectionalload mode with less than 100us load change capability, simulating a variety of different true load currentwaveforms.


SYSTEM INTEGRATION AND SUPPORT

The Chroma 87001 Battery Cell Simulator allowsusers to develop application software using theprovided SCPI commands, Labview drivers, andLabWindow drivers, or to integrate into the BMStest system with assistance from Chroma.

REMOTE CONTROL FUNCTION

A Chroma exclusive softpanel is provided to control the battery cell simulator allowing the user to :

  • Individually adjust the voltage of each string battery
  • Access the battery cell curve loading function to view voltage status changes
    according to the voltage compared with SOC.
  • Set the voltage change procedure: OVP/UVP/OVP release /UVP release test
