Chroma new battery management system power level hardware in loop test bench system, battery management system of the characteristics of the related parts and components equipment, including battery core simulation, simulated battery voltage and current, the temperature signal simulation, and provides various hardware choice for integration, such as dc power supply, digital meters, insulation measurement instrument, etc.

Chroma 8630 battery management system power level hardware in loop test system for the research and design of battery management system combined with real-time systems and open software architecture, provide flexible and powerful dynamic testing system, charge and CAN be introduced into the practical use situation, dynamic voltage and current measurement calibration, battery balance test, CAN signal measurement and control, fault injection, insulation measurement and simulation charging pile test project, related to the flexibility CAN be realized on the bench and the permutation and combination, so as to simulate verification to the environment is the most important and the failure of the riskiest composite operation situation (such as: cycle discharge of communications and the real signal failure), in does not need to actual battery pack in real vehicle or test under the condition of the battery management system for further test, improved the development efficiency.

Complete Chroma 8630 simulation system of communication and operation, to the simulation of the battery pack fast dynamic charge and discharge flow, different batteries, temperature signal, the system insulation resistance, etc., containing the various protection function test battery management system.Its configuration, high precision programmable power supply according to the actual working condition of set arbitrary or recording, cover more comprehensive complete system dynamic testing.

Chroma 8630 can simulate dynamic system for dynamic load and back filling behavior, including batteries, high voltage and high current balance current, battery, and support the Altair Activate vehicle Model and various kinds of Simulink Model - -based real-time mathematical Model of the import, realize the NEDC, WLTP, FTP - 75 international standard such as vehicle Driving Cycle.In addition, also can turn signal measurement and control, fault injection, insulation measurement and simulation charging pile each test function, such as high elasticity permutation and combination to achieve complex condition, further to test object to be tested.

Chroma 8630 battery management system power level hardware in loop test system, not only can realize the past basic required function and signal control test, also simulated batteries balance current, high battery voltage and high current actual power behavior, compared with the traditional signal level HIL, more complete coverage of EV or energy storage systems such as power components testing range.Assist users to related components in battery management system standard V development process have more validation work right, include system level function and various compound condition test, before entering into a car test can early detection of problems and correct errors, effectively reduce the development cost and improve the test efficiency.

To cover all the more to the complex behavior, the operation of the actual vehicle industry in recent years, vigorously promote the ISO 26262 as a function of road traffic safety specification of each plant and its suppliers in the product development to follow the standard, ISO 26262 by the product system down to the hardware and software, in view of safety requirements put forward the content of which should be followed (functional safety requirements to technical safety requirements, hardware security and software safety requirements), and test verification is mentioned, no matter in any function (ASIL) safety integrity level, must be hardware in the loop and fault injection experiment was carried out, in order to ensure the correctness of the security mechanisms in the vehicle level and the effectiveness of failure coverage.

Chroma 8630 integrated Fault Injection Unit (Fault Injection Unit), in view of the system under all kinds of control and communication signal any open Fault test, and can be combined with dynamic discharge, insulation impedance changes with the static charge...Behavior such as simulation, so as to simulate verify the finished product is the most important and the failure of the riskiest compound operation situation, under the condition of without actual battery module to further test of battery management system, not only improve the design of the product, also with the ISO 26262 process fault injection test content, to achieve ASIL safe level certification.

Man-machine operation Interface (UI Interface) is a very important part of the test system, a direct impact on r&d testers operation convenience and execution efficiency, Chroma 8630 system default integrate all kinds of instruments and equipment to establish control and test program development environment, available for users to write, modify, test procedure, also allow users to edit the UI images, user sustainable optimization test projects and processes.

Analyte equipment and parameter display:

Such as battery charge and discharge status, voltage, current, power, power, protect alarms, insulation degree... etc, and with digital, instrument and drawing the way of updating the value.

Test programs needed to set the control parameters of the picture:

Such as battery charge and discharge start up and shut down, charge and discharge voltage, current, insulation measurement start, fault injection signal selection, choice of test conditions, etc., and to be able to change the form of digital, towing and switch control values.
