This bus has been specifically developed for demanding daily usage cycles, Jewel E meets the latest Transport for London (TfL) specifications and requirements for 2024, including enhanced safety features to give the public, drivers and passengers piece of mind.

Integrated into Jewel E’s chassis is Equipmake’s ZED Zero Emission Drivetrain, advanced propulsion technology; the HTM 3500 motor combines high torque with low motor speeds, and is fitted directly onto the propshaft negating the need for a gearbox.

The unit produces maximum torque of 3,500Nm at just 1,000rpm and offers maximum power of 400kW. It is driven by a Semikron SKAI inverter with energy stored in a 548kWh lithium-ion battery pack – enough for a range of up to 250 miles on a single charge, the largest battery available globally on a double deck bus, enabling more than enough daily operating mileage.

Jewel E’s efficiency is made possible by Equipmake’s ZED incorporating one of the most efficient thermal management systems on the market, which keeps the motor, inverter and battery at optimum operating temperature, featuring a water-glycol cooling circuit augmented by the capture of thermal energy to heat the interior in cold conditions.

When the battery is depleted, it can be simply recharged at the depot overnight using a CSS DC charging point.
