Swedish firm's battery simulator can help boost EV, eVTOL's range

Swedish company Aliaro has developed a Battery Cell Simulator (BCS) designed to enhance electric vehicle (EV) and electric vertical takeoff and landing (eVTOL) aircraft performance by enabling comprehensive testing of Battery Management Systems (BMS) without the need for real batteries. The simulator replicates battery cells and sensor behavior, allowing verification of communication, safety functions, cell balancing, and fault monitoring algorithms in a controlled lab environment. This approach reduces reliance on costly and complex real-world testing, accelerating development and lowering costs. Aliaro’s BCS employs a combination of electrochemical models and empirical data to accurately simulate lithium-ion battery cell behavior under various conditions, providing insights into optimal battery design parameters such as electrode thickness and porosity. The system supports both production and validation testing, facilitating a unified workflow and enabling EV manufacturers to optimize battery designs for improved range, faster charging, and greater efficiency. Demonstrated at the NI Days India 2025 event, the xVolt Battery Cell Simulator offers flexible,
