Brogen Delivering Electric Bus Battery Systems for 8-Meter and 12-Meter Battery Electric Buses (BEBs) in Türkiye
Project Overview
- Project Start Time: 2022
- Project Vehicle Types: 8-meter and 12-meter battery electric buses
- Country: Türkiye
- Systems Supplied: electric bus battery, PDU (with BMS), BTMS, EVCC
Project Introduction
In response to Türkiye’s growing environmental initiatives, a well-established Turkish commercial vehicle manufacturer embarked on an electric bus project, focusing on 8-meter and 12-meter models. Leveraging our expertise in electric bus battery systems, we delivered a tailored solution that included a 282 kWh battery system, a customized BMS, PDU, and a BTMS cooling unit, engineered to match the bus architecture and meet European certification requirements. This case study outlines our approach to overcoming technical challenges and providing comprehensive support throughout the project.
Client Background
The client, a prominent commercial vehicle manufacturer in Türkiye, has a strong reputation for producing traditional fuel-powered buses. In 2022, motivated by Türkiye’s environmental policies, the company shifted its focus to electric buses, initiating a new product for 8-meter and 12-meter electric models. Given our history as their supplier of EHPS and air brake compressors, they entrusted us with developing a high-quality electric bus battery system for their new fleet.
Key Challenges
- Custom Electric Bus Battery System Design: The 8-meter and 12-meter electric buses required different energy capacities, battery layouts, and installation architectures, demanding a fully customized solution for each model.
- Uncommon High-Voltage Architecture: The buses used a high-voltage e-powertrain, which is not a mainstream specification for electric bus battery packs. This required careful component matching, safety validation, and specialized system design.
- Space Constraints and System Integration: The battery packs needed to fit within limited chassis space while still delivering the required energy, cooling performance, and safety compliance.
How We Designed the Electric Bus Battery Solution
- Requirement Analysis & System Simulation
- Conducted detailed simulations and calculations based on the client’s vehicle specifications, including speed, range, and certification requirements.
- Designed custom battery packs with different capacities to meet the distinct needs of the 8-meter and 12-meter buses.
- Engineering Development
- Developed a specialized BMS tailored to the buses’ specifications.
- Created circuit diagrams and optimized the internal and external wiring to fit the vehicle layouts.
- Carefully selected connectors, considering power currents and interlock requirements.
- Ensured compatibility between the charging infrastructure and the battery system, adhering to European standards.
- Joint Testing & Validation
- Conducted joint testing with the client to verify the charging system’s functionality.
- Provided technical support during the installation and initial operation phases, including software updates and remote troubleshooting.
