June 14, 2023, China, On June 7th, the Sany MOTA 1165 electric heavy-duty truck, equipped with the independently developed MOTA battery, traveled from Changsha to Shenzhen on the expressway, covering the entire distance without recharging. With a single charge, it achieved a record-breaking distance of 817.5 kilometers, earning the honor of the longest single-charge range for a semi-trailer electric truck.

Empowered by the remarkable endurance of the MOTA battery, the Sany 1165, with a total weight of 40.45 tons (including the load) and an average energy consumption of 1.17 kWh/km, surpassed the challenge target by traveling 817.5 kilometers.

Sany has made a breakthrough by integrating the MOTA battery technology with the power distribution technology. The battery is directly integrated into the chassis, making the chassis and the battery inseparable. This chassis integration technology significantly reduces the use of unnecessary chassis wiring harnesses and components, resulting in a more streamlined chassis design.

With a total energy capacity exceeding 1100 kWh, the MOTA 1165 features a 40% increase in energy density, making it the largest on-board battery system in the heavy-duty truck industry.

The MOTA battery employs a brand-new architecture, reducing electrical connections by 80% and eliminating wiring harnesses and internal connectors. This not only reduces electrical risks but also greatly improves maintenance convenience.

Compared to commercial vehicle batteries on the market, the MOTA battery offers enhanced safety and stability. It adopts a new multi-loop control method, enabling each loop to function independently and significantly reducing the risk of cell failure.

Sany's self-developed Battery Management System (BMS) utilizes distributed control and precise monitoring of each individual cell. In the event of abnormalities, immediate feedback and appropriate measures are taken to ensure the safety of the cells.

The MOTA battery incorporates preset thermal management modes for different operating conditions, resulting in a 30% increase in overall thermal management efficiency compared to traditional battery packs. It also reduces heating time by 20% during winter and provides four times better insulation performance at -20°C compared to conventional battery packs.

The MOTA 1165 adopts an 800V voltage platform and features a specially developed four-gun supercharging mode, enabling a maximum charging power of 800 kW. It only takes 1.5 hours to charge from 10% to 90%, ensuring efficient charging capabilities.
