Common Battery Parameters Setting and Function Simulation

By combined various types of battery modelling and high-speed algorithms, BSS2000/BSS2000 Pro/BSS2000M Battery Simulation Software provide the user with real-time battery curve simulation function. No need to know the specific internal characteristics of the battery, the user only needs to select the battery type and the battery characteristic curve can be generated easily by setting a few basic parameters, parameters including full voltage, empty voltage, rated capacity, serial qty, parallel qty and battery internal resistance, etc. Thanks to the strong support of ITECH hardware, the battery simulator can simulate up to 1152kW battery packs, covering the test requests of solar PV ,energy storage, EV and other high-power fields.

User Defined Battery Characteristic

BSS2000/BSS2000 Pro/BSS2000M Battery Simulation Software provides the battery curve simulation function by importing Data to meet the needs of various simulation requests. Users can import the measured battery charge and discharge data in a csv file to simulate the battery charge and discharge characteristic curve. This function is not only suitable for the simulation of conventional batteries, but also for the simulation of some special batteries or novel batteries.

Support .mat File Import

BSS2000 Pro/BSS2000M battery simulation software provides professional battery researchers with the function of importing .mat files, through which users can simulate the corresponding battery characteristic curves under different battery mathematical models. This function is of great significance for the research on the adaptability of new batteries and products, and the application of conventional batteries in special environments. Conventional types of battery characteristic curves or mathematical models are generally based on typical conditions, and for new batteries or applications in special environments, engineers often need to construct new battery mathematical models to more realistically reflect the performance of batteries in specific application contexts . This function is specially developed for such applications. Users can build a new battery mathematical model through a third-party MATLAB * simulation platform and import .mat file into BSS2000 Pro/BSS2000M for simulation, and then verify the the battery's adaptability in practical applications.

* ITECH BSS2000 Pro/BSS2000M is the first software to allow .mat mathematical model of novel batteries, such as super capacitors.

BMS Protocol Self-Defined Function

The BSS2000 Pro/BSS2000M Battery Simulation Software can not only simulate the battery pack, but also provide the simulation function of the battery management system (BMS). The user can self-define the BMS protocol to match the application of different scenarios and realize the CAN communication with the external control unit. In the process of simulating the entire power battery system (battery pack + BMS), BSS2000 Pro/BSS2000M can regularly report major parameters such as the actual voltage, current, and remaining capacity of the battery simulator, so that accordingly the external DUT can quickly respond to different states of the battery simulator in real-time.

* ITECH BSS2000 Pro/BSS2000M is the first software that supports BMS protocol customization, enabling communication and interaction with external control units to simulate the battery in a dynamic environment.

Initial SoC Setting Function

The BSS2000/BSS2000 Pro/BSS2000M battery simulation software allows the user to set the initial capacity of the battery to study the startup characteristics or energy management characteristics of DUT when the battery is fully charged or depleted, without the need to perform real charging and discharging, and improve test efficiency

Real-time Parameter Monitoring

The BSS2000/BSS2000 Pro/BSS2000M battery simulation software provides multi-channel control function and supports preview function of edited curves. Meanwhile, during the test operation, the operating parameters and operating curves of the battery simulator are monitored in real time. In order to facilitate research and test personnel to trace the experimental data, the software provides report generation function, and the saved data includes voltage, current, power, SoC, charge/discharge status, and capacity.

Seamless Battery Charge/Discharge Simulation

In real life scenarios, such as the EV field, as the vehicle decelerates, accelerates, or brakes, the battery continuously switches between the two states of discharge and energy recovery. Therefore, the battery simulator also needs to flexibly switch between being charged and discharge status and respond in a timely manner according to external state changes. The BSS2000/BSS2000 Pro/BSS 2000M battery simulator benefits from the hardware advantages of source and load in one device, which can realize the seamless switching between charging and discharging, to simulate the characteristics of the battery more realistically.

Protection Parameter Settings

In practical applications, in order to extend the service life of the battery and prevent the battery from over-charge and over-discharge, the BMS (battery management system) in the battery pack will limit the safety range of the battery for different applications. When it is higher or lower than the protection limit value, the software cut down the circuit in time to protect the battery and DUT. BSS2000/BSS2000 Pro/BSS2000M battery simulation software supports multiple protection condition settings: SoC upper/lower alarm value setting, SoC upper/lower protection value setting; OCV upper/lower alarm value setting, OCV upper/lower protection value setting.
