Chroma 87001 battery core simulator is a two-way multi-channel and high precision, and programmable dc power supply, at the same time have a voltage source and current source function, it is a multi-channel dc power supply or the electronic load is used.Every machine has 16 channels, each channel can be set respectively through the software interface of voltage and current.

87001 battery core simulator can accurately simulate the lithium ion battery core, replace the battery in the condition of reliable safe core test battery management unit (BMU) or subsystem of the battery core measurement unit (CSC), suitable for application in the field of electric vehicle and energy storage battery related.

Section 87001 simulator can simulate 480 battery (< 240 s2p, voltage 1000 V) series battery core voltage isolation channels, so as to simulate the power of the battery core can provide the energy absorption and features;At the same time have the ability to monitor voltage and current measurement, each channel with 0 ~ 5 v voltage regulation ability and 0 ~ 5 a bidirectional current function, has the function of series and parallel between channels, can be in accordance with the current growth in the number of channels in parallel.

87001 battery core simulator for independent architecture of battery management unit (BMU), separate collocation software interface used;Also in view of the master-slave architecture battery management system (BMS), integration in BMS automatic test system, to fully automated tests, quickly complete product validation.

Tie-in customization Chroma BMS automatic test system, 87001 simulator can provide temperature sensor for each battery core, high-precision temperature simulation, each battery core temperature state to the battery management system (BMS) for testing.

Chroma 87001 battery core simulator with multiple protection function, such as: overcurrent protection (OCP) composition among, overvoltage protection (OVP), the lower voltage protection (UVP), fan abnormal protection (FANFail), and output voltage loop compensation, etc, to provide users a safe testing environment.

Chroma 87001 battery core simulator can simulate various battery core, current, voltage, and temperature changes below for built-in subsystem measurement unit of battery management system, shows the battery core simulator integration and demonstration of BMS automatic test system architecture diagram.

• When users need more than 16 series of battery core, core simulator can string more than one battery, support sets limit of 15 units of 87001
• Users can also through the Ethernet HUB 87001, independent connecting the upper controller in Ethernet bandwidth enough state, remote synchronization control applications, to more than 87001 voltage modulation orders at the same time, the single voltage control response time < 10 ms
• Hardware configuration limit can be configured 240 series 2 and voltage (< 1000 V), the simulator can support the channels in series and parallel coexistence, parallel state, battery core simulator with automatic flow design

Note: the control voltage response time (phase delay time) = upper controller command sending time + 87001 processing time + voltage rising/falling time

Chroma 87001 battery core simulator, provides the voltage source model and bidirectional current source, built-in 16 bits of high precision A/D converter, voltage measurement precision of plus or minus 1 mV F.S. (0.02%), voltage measurement resolution can reach 0.1 mV.

For the balance design of market trends, initiative and passive measurement current is divided into 4 files: 0 ~ 9 a (< 500 ms), 0 ~ 5 a, 0 ~ 500 ma, 0 ~ 250 ua, its power flow measurement accuracy of 0.02% f.s., 0 ~ 5 a gear (can increase the power parallel) precision of plus or minus 1 ma, conform to the requirements of the active balancing design line testing, electrical flow measuring resolution of up to 100 ua;0 ~ 500 ma precision for + 100 ua F.S. (0.02%), conform to the requirements of the passive balance design circuit testing, electrical flow measurement resolution can be as high as 10 ua.In addition to the passive balance design of the electrical flow measurement, can also be applied to the BMS PCB, consumption of electricity for battery core flow test (typically consume current > 10 ma).

• Chroma respectively with two commands (through network intersection SCPI and CANbus interface CANbus command), Labview driver, Labwindow driver, such as language, let users to develop applications to control 87001 battery core simulator
• Chroma system integration ability can provide customization system integration automatic test system, used for BMS functional testing

Note: the SCPI command is used to support 1 ms information sampling, verify the passive balance switch state
