The invention consists of a system for sharing rechargeable battery packs made available, for the means of transport of the users of the system itself, in appropriate charging stations distributed throughout the city. The monitoring and management of the service takes place through the exchange of data between the charging stations, the battery packs and a central control unit. The patent provides that packs of rechargeable batteries for soft mobility are integrated into appropriate recharging stations which, in addition to performing the function of recharging the individual packs, allow them to be shared among the users of the service. The user, enabled to access the service, can rent the battery pack to power his vehicle, for example a pedal assisted bicycle, and only bear the cost of recharging the battery. The patented system also provides a control unit for the management and monitoring of the service. The control unit, continuously connected to the charging stations and battery packs, will also allow users and the operator to be provided with the respective information of interest, such as the use of the battery packs, their state of charge and life. useful, their geo-localization, environmental monitoring and more.

The patent does not have a particularly extensive territorial scope of protection, however it protects a completely new solution with decidedly scalable industrialization and application costs and against a still long duration of exclusivity.


Soft and green mobility is largely implemented through sharing services, whose fleets are mainly composed of pedal assisted bicycles and electric scooters. A feature of these services is the extreme capillarity of the service offered but, in hindsight, they hide a significant environmental cost: the disposal of batteries which, after in some cases a few recharging cycles, are no longer suitable for transport, are difficult to repair and must therefore be replaced. Since the distribution of these vehicles is influenced by the movements of users, the quality and residual duration of the battery life of these vehicles is affected in a non-homogeneous way by the behavior of users, with a further increase in the fixed costs of managing the sharing system.

Current limitations of technologies / solutions

Soft and sustainable mobility, in particular with pedal assisted bicycles (e-bikes), represents the inevitable future of urban travel; however it is equally true that e-bike sharing systems are still a niche and that their real economic sustainability, in the event of widespread diffusion, is too conditioned by the education of users. Incorrect use of batteries, in fact, heavily affects the environmental footprint that current sharing systems entail.

The MondoBIKE patent aims to remedy this limitation of the system: on the one hand by making the owner of the vehicle responsible, on the other by reducing the costs (not only environmental) of managing the electric components of e-bikes.

Killer Application

The patented technology can be implemented in public transport systems consisting of soft and green sharing mobility, through a business case created in collaboration with public and / or local bodies, as well as companies already active in offering this type of services. The system would become scalable in a short time, both because it does not require the construction of batteries or ad hoc vehicles, and because it only requires the participation of people who, to date, already use muscular means of transport and therefore inclined to access an innovative service, based on better battery management.

Finally, this battery distribution network extends the range of the single-user electric vehicle to infinity.

Technology and our solution

The University of Florence (UNIFI) has patented a bike sharing system with potential extension to scooters, based on sharing the battery instead of the vehicle, capable of raising awareness, encouraging and facilitating the sustainable use of light vehicles in the environment urban.

This system overcomes many limitations of traditional sharing. The concept, in fact, is to separate the vehicle from the batteries: the user only has to transform his traditional bike or scooter into an electric vehicle, with special conversion kits made available but widely available on the market. It is a low-cost kit compared to buying an already electrified vehicle. In this way the user can have a network of recharging points in which to refuel charged batteries, without worrying about the management of recharging and maintenance and deterioration of the same. On the other hand, the service manager will not have the cost of the vehicles, which remain the property of the user. This also avoids the problem of vandalism and vehicles left parked everywhere.

The heart of the system consists of:

a) Charging stations located throughout the territory, which allow the withdrawal of charged batteries and the storage of discharged batteries;

b) Management app, which constitutes the user interface and allows you to carry out all the operations of identification, payment, withdrawal and storage of the batteries, provides information on the state of the battery charge, on the sites where the charging stations are located , the statistics of the routes, times, speed, etc. ;

c) Batteries with electronic cards designed to interface with the charging stations, with the management app and with the sensors on board the vehicle;

d) Conversion kit for traditional bicycles and scooters into electric vehicles, at low cost.

The system, organized in this way, combines the advantages of the user with those of the manager, minimizing the risks and costs due to the maintenance of the vehicle fleet, often the cause of the failure of bike sharing systems. The creation of an economically sustainable system, for all the actors, constitutes the sine qua non for the development and diffusion of a mobility system.


  • Real-time data on batteries;
  • Best shared transport service;
