Equipmake showcased its state-of-the-art of development and production of electric drivetrain for bus, and coach industries at Busworld 2023.
Equipmake unveiled the latest generation of its Zero Emission Drivetrain (ZED), a cutting-edge battery-electric powertrain designed and developed from the ground-up to deliver clean, cost-effective urban mobility.
Completely scalable and modular, the ZED can be applied to any bus, from single to double decker, and is suitable for coachbuilds as well as repowers of existing diesel vehicles. Featuring Equipmake’s in-house developed electric motor, inverter, and power electronics, combined with the latest in lithium-ion batteries, ZED’s advanced technology results in high efficiency.
One of its most important features is Equipmake’s patented ultra-efficient thermal management system, which maintains all three of the ZED’s key components – the battery pack, motor, and inverter – at an optimum operating temperature, maximising vehicle range.
Featuring an advanced water-glycol cooling circuit, the system has the added benefit of providing interior heating during cold conditions with captured thermal energy. When the battery is depleted at the end of a complete duty cycle, it can be recharged at the depot overnight via a CSS2 DC charging point.
State-of-the-art lithium-ion battery packs are available in a range of sizes, from 327 kWh to 436 kWh, up to 545 kWh, giving ranges up to 400km, while Equipmake’s HTM 3500 electric motor is seamlessly integrated into the prop shaft – without the need for a separate transmission – and has been precisely engineered to meet the demanding requirements of a fully laden bus by producing 3,500Nm torque at a motor speed of just 1,000rpm and delivering 400kW maximum power.
Every configuration carried out by Equipmake, whether coachbuild or repower, is bespoke to each vehicle and its requirements, with service routes simulated to ensure the optimum battery level is selected, and that required mileage is achievable. Equipmake also provides cost effective aftercare, with a motor, battery pack and inverter refurbishment programme.
