Mission Motors, developer of the high-performance Mission One PLE electric motorcycle, launched Mission Electric Vehicle Technology (MissionEVT), the company’s high-performance EV Powertrain Division, at the 2010 Specialty Equipment Marketing Association Show (SEMA) in Las Vegas.
MissionEVT will design and supply high-performance EV powertrains, including energy storage systems, drive systems and software intelligence, to the OEM market, targeting a wide range of vehicle applications—including battery-electric, plug-in hybrid electric and hybrid-electric vehicles. Mission Motors CEO Jit Bhattacharya said that the company already has contracts with two major vehicle manufacturers, and ultimately envisions producing electric powertrains—using its own as well as contract manufacturing capabilities—for application in OEM gliders.
The modular MissionEVT systems can be scaled up for use in large trucks or down for innovative personal transportation solutions as well as for motorcycles and light-duty vehicles, the company says. The powertrain division will also offer engineering and integration services.
With MissionEVT, our company will be able to expand into new markets, bringing the advances we have made in EV technology to multiple vehicle platforms and manufacturers. This creates a tremendous high-volume opportunity for Mission's powertrain technology, while solving a critical need for vehicle manufacturers trying to keep pace with the rapid electrification of vehicles.
Modularity is key to the MissionEVT solution. It gives us the flexibility to improve the performance of a wide range of vehicle applications. MissionEVT can configure our powertrain technology to work for applications ranging from powersports to automotive, and from battery electric to gasoline hybrid.—Jit Bhattacharya
MissionEVT leverages the work done by Mission Motors’ to develop its high-performance electric motorcycle, the Mission One PLE superbike. To meet the speed, range, packaging and dynamic requirements of the high-performance electric motorcycle, the company developed new battery, motor control, and vehicle software management systems, improving the weight, size, and modularity of these core components.
Mission One PLE. The Mission One PLE powertrain includes a liquid-cooled, 3-phase AC induction motor, single-speed transmission, and high energy Li-ion battery pack with integrated thermal management system. The motor outputs about 100 kW (an appropriate level for series hybrid applications, noted Bhattacharya) and 100 lb-ft (136 N&iddot;m) of torque. The electric bike has a top speed of 150 mph (241 km/h) and an estimated range of 150 miles. Recharging takes about 2 hours at 240V.
MissionEVT. MissionEVT offers energy storage, drive systems, software intelligence, and system integration.
Energy storage. MissionEVT’s energy storage system brings together a range of component technologies including: battery modules, battery management systems, onboard charge systems, and low-voltage vehicle power.
Drive systems. At power ranges between 10 and 150 kW, MissionEVT offers power-dense liquid-cooled motor solutions for a range of applications.
MissionEVT’s Motor Controller brings together advanced inverter technology and digital control in a single unit capable of driving more than 100 kW. This high-voltage controller introduces new techniques for efficiently removing heat from high-power electronics, according to MissionEVT, allowing the system to get more power from a simpler, lighter electronics package. Embedded at the core of the controller is a digital signal processor running MissionEVT’s Motor Control Software.
MissionEVT’s control software dynamically adjusts drive algorithms to maximize system efficiency across the drive cycle. The system also gives manufacturers access to control features such as adjustable regenerative braking, adjustable throttle maps, and automatic traction control. MissionEVT’s software has the flexibility to drive both AC Induction and Permanent Magnet motors, bringing MissionEVT motor control to a broad range of applications.
Software intelligence. MissionEVT’s “software intelligence’s has two main aspects: the Vehicle Management Software (VMS) and the Cell-to-Server data acquisition system.
Vehicle Management Software (VMS) monitors and manages every aspect of the vehicle and the powertrain, linking the energy storage system, the drive system, and the vehicle operator into a single network. Built on a Linux-based platform and running a safe real-time operating system, VMS continuously monitors the safety and performance of the electric powertrain. Designed using a CANBus architecture, the MissionEVT vehicle management system serves as a hub for MissionEVT components as well as client systems across the vehicle.
The Cell-To-Server data-acquisition system captures real-time battery and vehicle data (temperature, state-of-charge, power, speed, GPS coordinates, and more) and transmits it to a central server via cellular networks. This data set can be used to refine battery and vehicle design, reduce total cost of ownership, and enable smarter vehicle use by the driver. Tracking and analyzing performance across full-fleet deployments allows better maintenance tracking and sophisticated cost optimization. The Cell-to-Server system will also enable integration into the future smart-grid.
System integration. MissionEVT can support clients at all stages of product development, including Powertrain System Specification; Concept Design, Construction, and Review; System Engineering, Construction, and Testing; FMEA, Hazards Analysis, and Fault Tree Analysis; Safety and Regulatory Testing; Validation Prototypes Construction and Testing; and Volume Production.
