EV Miata provides detailed plans for your Electric Miata Conversion

Our kit plans provide you with all the information you need to create your own Electric Miata. Plans are based on our award winning Miata conversion.

Kits are designed specifically for the first (NA) generation.

Design Criteria

Keep the Miata Goodness

Miatas aren't the fastest or flashiest, but they are a responsive, great handling, and affordable sports car. +Our goal was not to lose this by weighing down the EV-Miata with batteries, or making it nose or tail heavy. +EV-Miata would be a fun to drive, affordable electric sports car.

Safety Requirements

+Steel battery racks are bolted to the vehicle's frame rails and are designed to secure the batteries in the event of an impact. +Fully insulated high voltage terminals keep wandering fingers from coming in contact with pack voltage. +Battery options are sealed to reduce or eliminate the possibility of spills of damaging or toxic electrolyte

Installation Requirements

+Our Design Minimizes Heavy work - the engine needs to be removed, but the transmission and rear sub-frame do not and only the trunk area needs to be cut. Mounts and brackets use the stock holes where possible. Common hand and power tools used throughout Clear, step-by-step instructions with illustrations Fabrication Diagrams can be taken to a local welder for fabrication or you can build them yourselves.

Flexibility Requirements

+Support for inexpensive lead-acid AGM, off-the-shelf lithium batteries as well as those from Leaf, Volt, Tesla donors. +Size the battery racks to support a variety of lithium cell brands and amp ratings. +Support for both off-the-shelf and donor motors up to 10" x 18" +Support for a variety of controllers brands both off the shelf and from donor vehicles. Support for a variety of Chargers off-the-shelf and from donor vehicles.

Configuration

Battery Racks

1 - The Nose Rack sits in the nose of the car and holds 4 Group 34 AGM batteries, or a number of Lithium cells either off-the-shelf options or from a donor electric/hybrid vehicle.
2 - The Top Rack sits above the motor and holds 4 Group 34 AGM batteries, or a number of Lithium cells either off-the-shelf options or from a donor electric/hybrid vehicle. It also provides the mounting points for the vacuum pump, DC/DC converter and High Voltage Enclosure bracket.
3 - The Trunk Rack sits below the trunk floor so that trunk space is optimized. The Trunk Rack holds 5 Group 34 AGM batteries, or a number of Lithium cells either off-the-shelf options or from a donor electric/hybrid vehicle.

Mounts and Brackets

A - The Motor Mounts firmly mount to the stock motor mounts.
B - The Controller mounts on the Controller/Charger bracket above the Nose Rack and will support a number of different controller options. This bracket will provide a secure mounting point for a number or different controller and charger options.
C - The front mounted Charger also mounts on the Controller/Charger bracket above the Nose Rack. For larger chargers or controllers, the charger could be mounted in the trunk - see item E below.
D - The High Voltage Enclosure mounts on the HVE bracket on driver side of the Top Rack. It contains the Contactor, Controller Fuse, Auxiliary Relay and Ammeter Shunt.
E - The charger port replaces the fuel cap under the fuel door. A J-1772 connector (recommended) or other electrical connector can be used in this location.
