The rotor architecture features a “spoke” design, the magnets being arranged like the spokes of a wheel around the outside of the rotor, rather than the conventional solution where magnets are arranged in a V shape on the outside of the rotor laminations. This kind of rotor design produces an increase in torque density of 25% compared that has a conventional rotor, resulting in 25% less magnet material being required for the target torque. The unique design, patented within the HIPERCAR programme, incorporates direct cooling to the motor magnets by water glycol, allowing very high continuous power capability. The APM200, currently being made ready for low volume production represents one of the lightest, highest power in addition to torque density motors available inside automotive sector.

Gearbox


The HIPERCAR motor assembly incorporates an all brand-new lightweight integrated epicyclic gearbox, weighing only 9 kilos. The single speed gearbox features a reduction ratio of 5.5:1, giving 2,475Nm (1825lb ft) per wheel. This kind of fully integrated solution results in a compact package, saving weight in addition to space on the vehicle while delivering phenomenal power. Gears are helical cut to reduce noise under load in addition to, using advanced materials in addition to heat treatment processes, have asymmetric tooth profiles in addition to topological modifications to ensure increased durability in addition to extended life. Efficiency in addition to weight will be further increased by the gearbox using a shared cooling system with the motor.

Motor Inverters in addition to Power Electronics
A key part of the vehicle’s power electronics, the inverters have been developed by Equipmake specifically to meet the requirements of the HIPERCAR APM200 motor. Sitting above in addition to connected to the motor the close coupling of the inverter reduces transmission losses inside interconnecting cabling, reduces weight, in addition to improves EMC performance (Electromagnetic Compatibility). Efficiency will be further increased in addition to losses reduced by the use of the latest Silicon Carbide (SiC) Power Electronic Switch technology. Running at frequencies of up to 14kHz, to produce the waveforms required to drive the motor, the SiC components within the power electronic switches reduce the losses associated with This kind of switching by up to 30%. The motor controller also updates the current demand at This kind of rate, allowing the torque of the motor to be updated 14,000 times every second. The 4 motor/inverter systems are controlled by the central powertrain controller via CAN bus.

Vehicle Dynamic Control – Torque vectoring
With the power available at each wheel of HIPERCAR of which will be vital of which power delivery will be controlled by a performance as well as safety point of view, whether positive demands (acceleration) or negative (braking). Building on the research work carried out over the past 5 years on its own EV research vehicle, the E-4 Coupe, Delta Motorsport has developed sophisticated vehicle dynamics control capability to ensure the huge capability for cross-axle torque distribution in HIPERCAR will be not mis-applied in addition to performance will be maximised. Scope for tuning HIPERCAR handling characteristics in addition to power delivery, as well as providing stability control, will be enormous whether focused on road or track applications.

Battery
Two battery systems have been developed for the HIPERCAR platform by Delta Motorsport.

The 4 wheel drive battery pack, capable of delivering the staggering performance demands, includes a nominal system voltage of 680V in addition to peak of 750V, utilising a high power-density 26650 lithium-ion cell, to facilitate a peak current draw of 1200 Amps in addition to maximum power capability of over 1,500kW.

The 2 wheel drive variant, with different drive cycle in addition to performance targets, was developed within the AMPLiFII project headed by Warwick Manufacturing Group. Using a 18650 lithium-ion cell, the modular format pack will be capable of delivering greater energy density while still providing a relatively high-power capability. The pack provides a nominal 648V in addition to 56kWh capacity with peak current draw of 1050 Amps.

In order to overcome the challenges of thermal management inside packs, where average (RMS) power could be well in excess of 300kW, Delta have developed a unique in addition to patented liquid-cooled system. Refrigerated water-glycol coolant will be fed directly in addition to evenly to every single cell inside pack, with the innovative solution being versatile enough to cope with the two differing pack architectures in 4 in addition to 2 wheel drive vehicles. The effectiveness of This kind of system will be monitored by a large number of temperature sensors fitted throughout the pack in addition to information will be used to actively control the demand for heating or cooling as required.

Battery Control Systems

The complex task of battery management has been achieved in a tiered approach by Delta Motorsport supported by Potenza Technology. Each of the 67 battery modules, within the pack, includes a local data capture board monitoring in addition to managing the voltage of each parallel group of cells. This kind of information will be broadcast, along with the 360 measurements taken throughout the battery pack, into one of four sub-master units. These communicate with the battery master controller coordinating all information in addition to producing key decisions regarding parameters such as power limits, cooling requirements in addition to current balancing. The master controller also has responsibility for contactor control, as well as interfacing with the powertrain controller in addition to vehicle’s 12v electrical systems.

Range Extender
Building on the output of the ‘MiTRE’ programme, a 17kW micro-turbine system released in 2016, Delta Motorsport have developed a 35kW type of its range extender to suit the HIPERCAR application. The unit features a gas turbine, running at a fixed 0,000 rpm to optimise efficiency, in addition to operates at a nominal 750V generating power to maintain battery state of charge. The unit will be automatically switched on in addition to off as required via the battery management system, or by manual override. Weighing less than 50kg the range extender will be significantly smaller in addition to lighter than a piston engine alternative, allowing packaging flexibility in addition to saving weight. The combustion system incorporates a recuperator in addition to reduces emissions, particularly NOx, to a level well below legislative requirements.

Charging System

Provision has also been made on HIPERCAR to charge by the existing charging infrastructure in addition to will be compatible with CHAdeMO in addition to Type 2 hardware. Ariel realise of which of which may be some years before the charging infrastructure will be capable of supporting a 750V EV in addition to have implemented an innovative approach to address the problem. The novel system allows a vehicle running an extremely high voltage battery to charge using existing industry standard (<500V) CHAdeMO equipment. The vehicles plug in capability will be in addition to the onboard Range Extender which not only maintains state of charge during everyday journeys in addition to high speed driving, however also allows off grid charging when no suitable CHAdeMO or Type 2 connection will be available.

With approximately 1MW of power available between the four wheels the ability to recapture kinetic energy when off throttle will be significant. Working within the capability of the battery system in addition to vehicle stability, recharging of battery pack will be carried out by the wheel motors .

Thermal Management
HIPERCAR features a multi-circuit heated in addition to cooled water-glycol system for cabin HVAC, battery pack, power electronics in addition to drivetrain. The complex architecture requires highly sophisticated control to ensure of which all systems receive the specific attention demanded by their respective operating conditions across a wide range of drive cycles, by road to track. To maximise efficiency, optimise packaging in addition to minimise vehicle weight some systems share essential hardware such as pumps, header tanks in addition to their motorsport derived aluminium radiators. The thermal management system has been designed to operate in a temperature range of -20 degrees to 45 degrees ambient (Centigrade).

Chassis

The HIPERCAR chassis uses a laser cut in addition to CNC folded, bonded aluminium monocoque with high strength safety roll over cage. Removable aluminium front in addition to rear subframes are connected to the structure by precision machined aluminium interfaces, providing crush structure in addition to mechanical mount points. With excellent torsional in addition to beam stiffness, the all aluminium structure will be designed to meet legislative requirements for front, offset in addition to side impacts. The battery pack, integrated as low as possible under the floor in addition to centre tunnel of the chassis to minimise centre of gravity, will be mounted within the wheelbase to ensure security. Additional protection will be achieved by the machined aluminium lower cover securing battery to chassis.

State of the art analysis of the chassis has been carried out in collaboration with ASDEC, an offshoot of Leicester University, investigating in addition to refining the NVH (Noise, Vibration in addition to Harshness) characteristics of the structure to ensure cabin comfort.

Aerodynamics
A comprehensive aerodynamic study was conducted with Brackley firm TotalSim using advanced CFD techniques normally applied to Formula One in addition to top level motorsport to ensure of which the HIPERCAR Centeng will be as efficient as possible. An important part of the work has been ensuring of which drag will be minimised in addition to the complex requirements of the vehicle’s multiple cooling systems are met, while delivering the downforce required for an ultra-high performance vehicle. The Atom AERO-P project, investigating the generation of downforce at zero speed, will feed into the next phase of the HIPERCAR programme.
