ev battery pack for bus

Standard EV Battery Pack for Electric Bus / HCV​

The EV battery system is the core component of a battery electric bus, and its importance cannot be overstated. Our standard EV battery pack for electric buses and HCVs is designed with modular flexibility, allowing tailored configurations to meet various vehicle requirements. This approach reduces redundant design and production efforts, enhancing efficiency across R&D, procurement, and manufacturing processes for OEMs (automotive manufacturers) and ultimately lowering costs. Additionally, the standardized battery pack design ensures high levels of protection, safety, and reliability, supporting large-scale production demands.

Our EV Battery System Benefits

  • Premium Battery Cell

    We use battery cells from top global EV battery suppliers such as CATL, paired with a cushioning design in the battery cell and module space. This design quickly absorbs expansion due to battery "breathing" and provides added protection in collisions, enhancing overall battery safety.

  • Excellent Thermal Management

    Our standard EV battery pack features a liquid-based thermal control system that manages heating and cooling. This system optimizes battery consistency, enabling efficient heat dissipation, high durability, and reliable long-term performance.

  • Lightweight Design

    With aluminum alloy composites, the battery box achieves reduced material thickness without compromising structrual integrity. This approach ensures a lightweight design, further enhancing the energy density of the EV battery system.

Highly Integrated EV Battery Solution for Enhanced Quality, Efficiency, Safety

Case Study

turkey electric bus project with our battery system

8-Meter and 12-Meter Electric Bus Project in Turkey

In 2022, a leading commercial vehicle manufacturer in Turkey approached us for a custom EV solution for their 8-meter and 12-meter electric bus project. Drawing on our expertise in EV battery systems, we delivered a tailored solution that included a 282 kWh battery system, a custom Battery Management System (BMS) with a Power Distribution Unit (PDU), and Battery Thermal Management System (BTMS).

This battery system was adapted from our standard EV battery packs, but the buses’ 700 V high-voltage motors posed a unique challenge, as this voltage is uncommon in battery packs. To address this, our engineering team conducted detailed simulations and calculations based on the vehicle specifications and developed custom battery packs with varied capacities to meet the specific requirements of each bus model.
