Tier 1 provider Marelli has been chosen because the provider for the inverter, which it says is a core part of the electrical engine for the brand new BMW CE 04 electrical scooter. The inverter is designed to optimise the utilisation and reuse of power, maximising efficiency and effectivity.
The inverter allows the conversion from DC (Direct Current) energy derived from batteries to 3 section AC (alternating present) electrical energy wanted for the electrical motor. The firm says bike electrical functions transfer the challenges to the next stage, as they’ve to suit stringent dimensional limits, have to work in an exterior setting (dealing with excessive cold and hot circumstances, water and humidity, amongst others.) and require excessive energy density.
In specific, the inverter for the BMW CE 04 electrical scooter delivers 43.5 kW peak at nominal voltage of 145 Volt, with full efficiency (300 Ampere rms) within the 115-175 Volt vary.
This sort of inverter developed by Marelli options distinctive traits corresponding to flexibility and a scalable structure, as it might have extra highly effective variations (as much as 450 Ampere rms – 348 Volt) becoming in the identical house and dimensions.
Hannes Prenn, president, Marelli’s Vehicle Electrification division stated, “The inverter technology is a key enabler to ensure efficient energy management in every electric vehicle. That’s why we continue to design advanced solutions in this field, both for four-wheels and two-wheels, to complement our electrification offer, that also includes electric powertrains and thermal solutions.”
The inverter software program can be developed by Marelli, with BMW offering the automobile software program, hosted by an ECU positioned in the identical inverter case. The software program is compliant with Autosar (AUTomotive Open System ARchitecture) requirements and particularly customised for the diagnostic requirements required by BMW. Functional Safety necessities are compliant to ASIL B (Automotive Safety Integrity Level B) customary.
