Enrev technology

Temporary batteries for mass-market electric cars

R&D activities

Enrev’s main goal is the development of temporary batteries that provide electric cars with energy when they need it.

The research and development activities on these batteries span five key topics:

  1. Characteristics of temporary batteries and compartments.
  2. Control systems and algorithms for temporary batteries.
  3. Power control systems and algorithms for vehicles employing temporary batteries and a permanent battery.
  4. Battery swapping units and stations.
  5. Battery swapping network optimization.

Featured project: construction and demonstration of a real-scale temporary battery prototype.

The goal of this research project is to build a temporary battery with the dimensions and storage capacity required for its real application, plus a compartment that allows studying battery swapping operations, and the auxiliary electrical equipment to handle a bidirectional power exchange of up to 10 kW. The project is carried out with the participation of e+ ingeniería and the University of Oviedo Power Supply Systems (SEA) research group, and partial funding from the Economic Development Agency of the Principality of Asturias (IDEPA).

Industrial property

These research and development activities have resulted in key innovative solutions that enable the use of temporary batteries in electric vehicles, the recording of information about the operation of these batteries, their interaction with other electrical systems in or outside the vehicle, and battery swapping. These solutions have been granted protection through patents and utility models in different regions.

The applications for protection of Enrev industrial property, and for the international extension of this protection, have received financial support from the Spanish Patent and Trade Mark Office (SPTO) patent and utility model promotion subsidies under file numbers FPE-1390-00-20192, FPE-0021-00-20202, FPE-0021-00-20203, FPE-0049-00-20212, and FPE-0049-00-20213.
