Milestone Technology Developments working with world-class teams
QWC focus and expertise in high end zero compromise electric drive trains often leads to need to develop new technologies to achieve customer goals. Prior to development of any new powertrain design and potentially new required technologies, is a well thought out top-down systems engineering and tradeoff analysis using the complete set of customer short and long term project requirements. In some cases, competitive landscape and technical evaluations are required to assist customers refine their requirements to attain their long term product objectives.
Some of the more recent projects include development of new technologies using optimal control of one motor per rear wheel torque vectoring. This new Electronic Differential technology for rear-wheel drive (1 motor per rear wheel) was developed for this e-track/sports car project, which delivers torque vectoring, electronic stability control and traction control for improved high performance handling. In addition, this project utilizes active chiller cooling for the ESS to maintain temperatures for higher continuous power delivery.
Past work, QWC consulting for powersports company MotoVox managing their e-Vehicles development, led QWC to choose EVDrive in 2012 to co-develop this unique project. At that time, this was an industry first, one electric motor per wheel, 4×4 AWD Torque Vectoring powertrain, which involved, evaluating and then converting a top OEM 4-seat UTV (side-by-side), the Teryx-4 from Kawasaki. The new technology developed for this project was the AWD torque vectoring control using one motor per wheel. With this unique powertrain, the vehicle can deliver higher levels of safety, and pushes the boundaries of performance required being the first “Zero Radius Turn UTV” ever demonstrated. This all-electric powertrain prototype was designed for series PHEV (using a custom efficient motorcycle engine based REX – range extender). This high Powered Electric 4 seat Teryx4 UTV (side by side) (PHEV capable) with AWD Torque Vectoring and 1 motor per wheel inboard (where they should be), uses 4 of our QWC/SEV-35kW peak-132Vdc drive sub-systems, totaling 140kW or 188hp peak, powering the Teryx4 UTV/side-by-side off-road vehicle as a tech demonstration of this new technology.
Two other systems we offer are ideally suited for this 4×4 architecture which could be engineered for UTVs and other vehicles, that is: 4 x QWC/SEV-50kW peak-96Vdc for 200kW or 268hp peak total power or 4 x QWC/SEV-55kW peak for 220kw or 295hp peak total power.
Past work, QWC consulting for EVDrive – Another milestone torque vectoring technology project was the design and analysis for the prototype powertrain EVDrive developed for the the Nikola One prototype (QWC staff technically managing for EVDrive), specifically, the AWD 6×6 1200hp powertrain part of the prototype project (one motor per wheel – clutchless 2 spd custom gearbox on each motor), of this zero emission hybrid electric long haul semi-truck, that aims to fundamentally change how freight is transmitted globally from the perspective of cost, performance, safety and environmental impact. For this project many new technologies were designed/engineered, such as the 4 x 80kWh custom ESS (another pix) , custom DC-DC (another pix), the PDUs, custom ESS chiller, high performance active cooling system and many other sub-systems. The novel powertrain used a custom 320kW gas turbine as its Range Extender (REX).
Past work, QWC consulting for EVDrive – Electric Corvette C6 Sets Another World Electric Vehicle Land Speed Record – ANOTHER RECORD BROKEN FEB 16, 2017 – NEW STANDING MILE SPEED RECORD AT 209 MPH! 700+hp RWD Custom EVDrive-Train™ powered Z06 c6 Corvette pre-production prototype for Genovation Cars, NOW HOLDS TWO RECORDS – Earlier this year, the car Set New Street Legal World Electric Car Record in a standing mile driven by Johnny Bohmer reaching 186.8 mph , Custom ESSs -> https://goo.gl/LbgLxa AND THEN BREAKS ITS OWN TOP SPEED RECORD and sets a new record WITH 205.6 ON JULY 27, 2016 in a running mile (VIDEO -> https://goo.gl/CYO8sW ) The car did 189.451 mph in the standing mile breaking its standing mile record of 186.8 set earlier this year. The 205.6 mph was the final top speed which took ~1.5 miles – Press Release. VIDEO of 206.5mph top speed run -> https://goo.gl/CYO8sW (re: difference in top speed between a standing mile and a running mile – a C6 ZR1 Corvette can reach 202 mph in a running mile, but only 179 mph in the standing mile) Latest records will be officially posted on this site –> http://internationalmileracingassociation.com/index.htm “We are so proud of the team that designed/engineered, systems integrated, procured all parts and fabricated this custom Drive-Train for this OEM client, without them, these EV record breaking milestones would not have been possible, so a big thanks and congratulations to team and partner suppliers”, says Steve Tice, CEO/COO of EVDrive Inc.

Past work, QWC consulting for EVDrive – Electric “Harley Street Glide” RWD tour/parade/law enforcement event bike prototype for OEM – Electric touring bike concept designed and built by EVDrive – EVD110LV drive sub-system plus custom gearbox, cooling system and liquid-cooled ESS (battery/BMS sub-system) (if greenlit for production, design will be quite different with custom frame, sculpted cosmetic side panels, etc) Test run video – https://youtu.be/5LBYc59irsQ
Past work, QWC consulting for EVDrive – Toyota LC HZJ79 4×4 truck production truck conversion kits – Delivery of first production run of kits from EVDrive to ENS Industrial (OEM customer – gallery), began in 2016, and ENS installed the kits in the trucks to deliver to its Canadian Mining OEM customers. This BEV (“battery electric vehicle” or called “all-electric”) powertrain uses a 68kWh battery sub-system (or called “ESS”). Of significance is the compact onboard 70kW Fast Charger, AN INDUSTRY MILESTONE.

Standardized Swap-able Battery Module, Vehicle Carrier and Charging System Design for Electron Fuel Systems – this exciting project targeted fleets where their vehicles could be upgraded to hybrid by addition of a driveline electric motor plus swappable battery module system. The vehicle mounted battery module carrier contained the WEG (water-ethyl-glycol) cooling loop and the battery modules thermal heat transfer occurs through conductive contact with the carrier interface walls to the battery module.
