Have you electrified your depots or are you in the process of doing so? Congratulations! Dreev supports you at the beginning or during your project to ensure the lowest charging kWh price on the market and to run with the least carbon-intensive electricity possible!

Connect to our platform to smartly charge your depots.

Dreev is the leading flexibility operator for electrical depots in France and Europe

The best solution on the market for reducing the TCO of your electric fleet

Dreev optimizes charging in real-time based on electricity market price fluctuations. Depending on the structure of your electricity supply offer, part of the savings is generated directly on your electricity bill, and another part is returned in the form of a cashback. Each case is unique, and we support you to help optimize your depot charging costs as best as possible. Hundreds of buses and trucks are already managed this way!

A tool for controlling your electricity bill

Dreev optimizes charging based on your electricity tariff and the real-time evolution of the spot electricity market. The savings are visible on your electricity bill and as a rebate at the end of the year. Through this management, we can help you achieve savings of several tens of percent on your kWh price. Of course, we offer to estimate the expected savings from the charging management in advance. Dreev takes a partnership approach and is compensated through a percentage of the savings achieved.

A complete vision for global optimisation

Our optimization engine complements your supervision or smart charging system. It takes into account:

  • The energy needs of each vehicle (SoC management) and the vehicles’ entry/exit times.
  • The power constraints and characteristics of the chargers, vehicles, BMS, transformers, and other anticipated site consumptions, etc.
  • The various tariff parameters of your electricity bill.
  • The aging parameters of your batteries.
  • Any solar production or storage means on site, with a 24-hour forecast view.
  • The forecast view of real-time electricity prices, regardless of your electricity tariff.
  • Participation in energy market mechanisms to generate revenue.
  • The potential of your vehicles to discharge energy into your buildings or networks (V2G).

Having a comprehensive view of all the parameters of the depot allows for leveraging charging (and discharging) flexibility to minimize TCO while ensuring each vehicle is charged to the specified level and time.

Compatible with most charging solutions on the market

Dreev has opted for an open solution with an API accessible to all. Our platform can be seen as an add-on to a wider monitoring solution. Our API conforms to REST architecture and uses standard HTTP methods to perform operations.

We offer all partners the opportunity to connect to our API in order to control charging and facilitate the electrification process.

How it works

The Dreev platform optimises the recharging of electric vehicles according to electricity markets and users’ mobility needs. We can therefore be seen as an optimisation tool designed to make the most of the flexibility offered by recharging the batteries of electric buses and HGVs.

We are therefore different from the supervision platforms that monitor the charging points and trigger action in the event of a malfunction. Dreev is a complementary tool to these supervision platforms, with which we are forging partnerships. We make our API available so that these supervisors can connect to our platform.

An example of optimised depots: RATP’s electric buses in Paris


The adoption of electric buses significantly reduces CO2 emissions, up to 80% compared to thermal buses. In the face of the climate crisis, European regulations are imposing drastic emission reductions: 90% by 2030 and a total ban on the sale of thermal buses in 2035. In this context, the rise of electric buses is inevitable and their development will accelerate in the coming years. To support this transition, it is important to control the cost of charging, a key element for the economic viability of these vehicles.

Dreev offers an innovative smart charging solution to optimize the operating costs of electric buses. RATP, in Ile-de-France, has chosen Dreev to manage the charging of its fleet of several hundred electric buses. This intelligent system adjusts charging according to changes in electricity prices on the market, thus guaranteeing optimal charging at the best possible cost. This approach allows RATP to achieve substantial savings on its electricity bill, without affecting the comfort of Parisian passengers.

In addition to financial savings, Dreev’s smart charging system has a major environmental advantage. By avoiding charging buses during peak electricity consumption periods, RATP helps to promote the use of the cleanest and least carbon-intensive energy sources.

Dreev is positioning itself as an ideal partner for public transport operators in France and internationally, enabling them to optimize the charging costs of their electric buses while reducing their environmental impact.
