Use battery simulator BCS system to accelerate your BMS development and testing. For over a decade, we have been at an excellent level in battery management system (BMS) testing. We ensure that your BMS is optimized, safe, and robust. Use battery simulator BCS to test and optimize your active or passive balancing algorithm to expand the range of electric vehicles, optimize battery health and aging.

We provide a large number of module combinations for BMS testing, with scalable variants and different functionalities: with its modular design, the battery simulator BCS is combined with standard components to provide a wide range of customized solutions. Due to this flexibility, we can implement systems of different scales to best meet customer needs.
We offer portable desktop systems with 12 to 36 units. These systems are highly suitable for chip manufacturers, startups, or entry-level research. We also provide medium-sized systems with 24 to 60 batteries for developers of battery management systems or active and passive balancing systems. We can also provide large racks with 204 or more batteries according to customer requirements.
For all battery simulator BCS systems, the battery management system can also be tested from battery level to battery pack level. By using them, you can ensure the development of a safe, energy-efficient, long-lasting product with remote and reliable range indication. Regardless of their size, all of our systems can be configured as line end variants to achieve continuous operation and high precision (less dynamic).
The battery simulator BCS is the core component of the BMS testing system. Each module contains 12 virtual batteries that simulate real batteries in electric vehicles. All of their characteristics can be parameterized and therefore provide all necessary battery level states to the battery management system in a highly accurate and dynamic manner. Static testing can be conducted to extensively validate balancing algorithms and security mechanisms, including combinations of multiple errors. In addition, integrated and differently parameterized Comemso battery models can be used for dynamic testing on each battery or connected Matlab model. Through dynamic testing, the charging status (SOC), health status (SOH), and historical logging function of BMS can be checked. The electrical simulation of virtual battery cells not only enables users to conduct extensive, safe, repeatable, and fully automated testing of BMS. With the open interface of various software toolchains, we provide flexible choices for different customer needs and offer a powerful and easy-to-use testing system with very short training time.
A power supply unit (PSU) is a unit in the system that provides appropriate isolation module voltage for battery cell modules. By regulating and stabilizing the voltage, it can ensure the required current under different load conditions. According to the size of the test bench, there are two variants of power supply size. In addition to modules, other components of Comemso can also be provided.
SwitchBox has many tasks. On the one hand, it is a safety distribution box for testing various components of the system, suitable for 1 or 3 phases, 110/230V-220/400V. It is equipped with a main switch, emergency stop switch, and various safety mechanisms, which comply with safety guidelines, making it an important component of the entire test bench safety. There are different versions with different security features, such as isolation monitoring, emergency stop chains across multiple systems, or remote control, to meet the needs of each customer.
The fault simulation unit (FSU) simulates a broken wire in the cable connection between the battery management system (BMS) and the simulated battery unit. This error situation can be separately set and simulated for each FSU module between 1 or up to 120 cells simultaneously. This allows for checking the BMS's response to broken wires in battery cell measurements and balance lines, as well as simulating the "bonding" between BMS and battery cells - with different sequences and arrangements.
NTC/PTC temperature sensors are used to simulate temperature related resistors in the range of 0 Ω to 8.1 M Ω with high resolution. It allows simulating thermal behavior by changing the resistance. In addition, it is also possible to simulate fault situations such as short circuits and cable breaks. Therefore, it can represent the behavior of the battery management system under different simulated temperatures and electrical faults.
The dual channel R-ISO detection card simulates the insulation resistance within the high voltage range between DC+to PE and DC - to PE. The resistance value can be set within the range of 20 kiloohms to 65 megaohms. This function is very important because the BMS must detect potential hazardous isolation faults/connections between the battery and the chassis or other external components of the battery to predict lifespan and limb.
