ONE SYSTEM - UNLIMITED APPLICATIONS!
Ampere EV is the leading developer of complete electric powertrains designed for vehicles. Ampere’s turnkey Atom Drive System was developed by world-class engineers, it’s built in-house, pre-configured, and ready to install. Ampere EV’s powertrain systems are in-stock and ready to ship, and include everything needed for a hassle-free EV vehicle build.
THE COMPLETE EV Powertrain system
DESIGNED, TESTED & ASSEMBLED IN-HOUSE
VEHICLE CONTROL UNIT (VCU)
This is the central commander for all the vehicle’s electronics. Ampere EV engineers spend countless hours creating and testing torque maps on supported motors, assigning safety parameters, programming cooling loops, establishing charging protocols and much more. Ampere engineers have also integrated and validated that all the sub-systems, like powered accessories, work properly. The end result is an EV conversion system that is fully calibrated and tested for safety and performance, leaving the installer with the simple task of connecting the VCU to plugs on the wiring harness.
HIGH VOLTAGE JUNCTION BOX
This is like a fuse box for an EV’s high voltage (HV) electrical system – the one that powers the motor – and it includes high voltage contactors (HV relays), HV fuses, pre-charge and discharge circuits for proper sequencing, and automotive-grade connectors. Ampere EV sourced the very best automotive HV components for its HV Junction Box, and its form factor has created enough demand from shops and other manufacturers that it is the only component Ampere EV sells separately from its Atom Drive System.
LEVEL I / LEVEL II CHARGER
Ampere EV provides a 6.6kW onboard charger with integrated 1.5kW DC-DC converter and a J1772 plug receptacle (charging port) standard for its Atom Drive EV Conversion Systems. CCS DC Fast Charging is available (visit our ADVANCED FEATURES page).

BATTERY Thermal Management SYSTEM
Batteries are sensitive to extreme hot and cold temperatures and operate best in a narrow temperature range. Ampere EV ensures the best performance and battery life with a standard heater and cooling loop that uses a proprietary, hydrodynamic optimized cooling plate in the battery modules to ensure stable temperatures. This calibration work is performed in-house and controlled through the VCU.
MOTOR, INVERTER & Charger Thermal Management SYSTEM
High Voltage electrical transmissions generate high heat, so keeping motor, inverter (the motor’s electronic controller), and charger temps in check is critical to ensuring long life for these components. Ampere EV accomplishes this by supplying an ambient cooling system specifically designed for the motor, inverter, and charger, which is controlled by the VCU.
BATTERY MODULES
Ampere EV’s Battery system was designed in-house and is comprised of battery modules with an integrated Battery Management System (BMS). Three battery modules make up a 42-kWh battery pack, with up to 6 modules available for 84 kWh. Each module is only 29.5” long x 20” deep x 6” wide (75cm x 51cm x 15.25cm), allowing installers to place them throughout a vehicle’s chassis for optimum fitment and weight distribution. Ampere EV uses new battery cells and assembles its modules at its factory, using a sealed aluminum alloy enclosure, premium temperature resistant adhesives, nickel-plated copper BUS bars, fire-retardant potting foam, and a proprietary cooling plate that allows coolant to extract maximum heat from the batteries when flowing through the heat exchanger.
DRIVE MODE SELECTION
Ampere EV provides a Digital Keypad or a Rotary Dial with its Atom Drive System for Drive Mode Selection (P,R,N,D).
TOUCHSCREEN INTERFACE
Choose an 8- or 10-inch diagonal touch screen Graphical User Interface (GUI, or ‘gooey’) for driver information and controls. The Ampere EV GUI includes navigation and CarPlay/Android connectivity, and has multiple pages that display system information including state of charge, estimated range and more.
HIGH VOLTAGE WIRING AND CONNECTORS
Ampere EV HV wiring harnesses come partially terminated with automotive-grade HV connectors, and can be fully terminated with connectors on both ends at your desired length prior to shipping (visit our ADVANCED FEATURES page).
12V POWER DISTRIBUTION AND FUSE BOXES
A great thing about converting an ICE car is that the vehicle’s 12V electrical system can be retained to power accessories like the lights, blinkers, wipers and stereo. The challenge is rewiring the existing system for your conversion, until now. Ampere EV’s 12V Power Distribution Boxes and 12V Fuse Box makes quick work of connecting an existing 12V system seamlessly with the Atom Drive System’s modern electronics.
LOW-VOLTAGE PIGTAIL HARNESS AND CONNECTOR
When we say everything you need is included, we mean it. This pigtail harness provides an easy connection from a vehicle’s 12V electronics to the Atom Drive EV Conversion System.
THROTTLE PEDAL OR THROTTLE CABLE ADAPTER
Choose a drive-by-wire throttle pedal or a throttle cable adapter that allows you to convert an existing throttle cable linkage to work with the Ampere EV Atom Drive System.
MOTOR SELECTION
In addition to selecting a motor that meets your power goals, it’s also important to consider the correct motor type for integration into a vehicle’s chassis. Some motors will work for direct-drive (no driveline), while other motors are more suited to indirect drive configurations (driveshaft with or without an additional gearbox like a transfer case). Ampere provides a Tesla Small Drive Unit as the standard motor in its systems, and currently supports six motor/inverter combinations:
- Tesla Small Drive Unit – (220 kW/300 HP, 330 Nm / 243 lbs-ft TQ)
- Maverick Drive Unit – (255 kW/342 HP, 550 Nm / 405 lbs-ft TQ)
- Cascadia Motion IM225 with SR309 Reduction Gearbox – (225 kW/305 HP, 500 Nm / 369 lbs-ft TQ) – Available with an SR309 Reduction Gearbox or TorqueTrends TorqueBox®
- Cascadia Motion iDM-190 – (225 kW/305 HP, 500 Nm / 369 lbs-ft TQ)
- DANA TM4 SUMO MV800 – (250 kW/ 335 HP, 775Nm / 572 lbs-ft TQ)
