TESTING BATTERY MANAGEMENT SYSTEMS (BMS) WITH THE BATTERY CELL SIMULATOR (BCS)

WE ENSURE THAT YOU GET YOUR BMS RELIABLE, SAFE AND ROBUST. Test and optimize your algorithms for active or passive balancing with the comemso BCS to enlarge the EV range and optimize health and aging of the battery cells.

We offer a large mix of modules with scalable variants and different functions: with their modular design, comemso’s battery cell simulators  offer a wide range of tailored solutions in combination with standard components. Thanks to this flexibility, we can implement systems in different sizes to best meet the needs of our customers.

We offer portable tabletop systems with 12 to 36 cells. These systems are ideal for chip manufacturers, start-ups or entry-level research. We also supply mid-sized systems with 24 to 60 cells that are of interest to developers of battery management systems or active and passive balancing systems. And we can also provide big racks with more than 204 cells in accordance with customer requirements.

With all comemso systems, battery management systems can also be tested from cell level to pack level. By using them you ensure that you develop a safe, energy-efficient and long-lasting product with long-range and reliable range indication. Regardless of their size, all of our systems can be configured as end-of-line variants for continuous operation.

AVAILABLE MODULES AND FUNCTIONALITIES

comemso Battery Cell Simulator

Latest Software / Firmware:
Gen 7: Rev. 12.1.0 / Gen 8: 8.1.0

BATTERY CELL SIMULATOR (BCS)

The BATTERY CELL SIMULATOR builds the core of any BMS test system. Each module contains 12 virtual bat­tery cells which behave just like real cells in electric vehicles. These can be parameter­ized in all their properties and can thus provide the battery management system with all the necessary states at cell level in a highly precise and dynamic manner. The electrical emulation of virtual battery cells enables the user to perform safe, reproducible and fully automated tests of the BMS.

comemso power supply

POWER SUPPLY

A Power Supply Unit (PSU) is the unit within a system that supplies the battery cell modules with the appropriate voltages and currents. By regulation and stabilization of the voltage it ensures the required currents at any given load state. Beside the modules also other components can be supplied.

comemso failure simulation unit

FAILURE SIMULATION UNIT

The Failure Simulation Unit (FSU) simulates a damage of the cable connection as well as faulty electrical connections between the battery management system (BMS) and the batteries. This failure case can be set and simulated individually between 1 or up to 120 cells. Thus it is possible to simulate a verification for the detection of a different sum of cell voltages to the pack voltage.

comemso NTC / PTC

NTC/PTC

The NTC/PTC is used to simulate a temperature-dependent resistance in the value range from 0 Ω up to 8.1 MΩ, with a high resolution. It allows to simulate the thermal behavior by changing the resistance. In addition, it is optionally possible to simulate the fault case of a short circuit and a cable break. Thus, the behavior of the battery management system at different simulated temperatures can be represented.

comemso Resistor-ISOlation card or device

R-ISO CHECK

The Resistor-ISOlation card or device simulates a drop of the insulation resistance in the high voltage range between DC+ and PE and DC- and PE. The resistance value can be set in the range of 20 kOhm to 65 MOhm. This function is important because the BMS has to detect a possible leakage/connection of the battery with the chassis or other components outside the battery.

comemso SwitchBox

SWITCHBOX

The SwitchBox distributes the power to the individual components of the test system and is suitable for 1 or 3 phases, 110/230V – 220/400V. There are many versions with different safety features like insulation monitoring, emergency chain or remote chain to meet any requirements of each customer. In case of an emergency the SwitchBox will stop voltage supply immediately to prevent injury of a person or damage to the system itself.
