Conversion Kit & Drive Kit for E-Vehicles

Entry to electrification for SMEs

For small and medium-sized vehicle and machine manufacturers, there is an opportunity to take advantage of the current electrification dynamics in previously consolidated markets. However, the development of e-vehicles can be costly and time-consuming. ecovolta aims to make your entry into electrification easier, cheaper and more plannable.

Perfectly tailored to lean projects

Easy entry into e-mobility

The evoTractionKit is the shortcut on the way to prototypes and small and medium-sized series. With the conversion kits, you cover a wide range of applications - from very small vehicles to boats. Less prior knowledge is required than for individual conversion projects.

Cost-optimised implementation of projects

The use of conversion kits significantly reduces evaluation and purchasing efforts. With delivery from a single source, you design supply chains more efficiently. If you wish, you can leave the warehousing to ecovolta. The result is: optimal costs and focus.

Plannable integration into the overall system

With the kit, you simplify all processes - from system design to homologation. This makes your integration project manageable. To ensure that every project is successful, ecovolta has its own integration team at your side.

Conversion kits for electric vehicles from experts

As a supplement to the traction battery, ecovolta offers complete electrification conversion kits. The know-how for component selection and procurement comes from the company's own electrification experience since 2018, which has made ecovolta known and established as an expert for the integration of electric powertrains today. The evoTractionKit conversion kits are particularly suitable for prototypes and small and medium-sized series.

Wide range of conversion options for e-vehicles

The ecovolta conversion kits allow the electrification of:

  • Smaller commercial and industrial vehicles
  • Compact construction and agricultural machines
  • Mobile machines
  • Boats

The offer is aimed at manufacturers, forward-looking workshops, system integrators and importers.
