- one solution is to install a storage battery system with potentially other energy resources such as photovoltaic panels.
- the batteries can be charged preferably in periods when the power demand is less than the subscribed power and discharge when the demand for power is high.
- An associated advantage is a reduction in the total installed capacity of parking lots due to the possibility of energy exchanges both strictly between vehicles (106) and between a vehicle (106) and other equipment. electrics (not shown) connected to the parking lot (not shown).
- Another associated advantage is a maximization of the load capacity due to the existence of multiple local energy sources (other vehicles (106) and potentially other storage systems).

- the charging station system is not ready to provide the requested service, provision may be made, for example, to reject the reservation request and, possibly, to offer another service. For example, a vehicle user wants to sell 40% of the energy stored in his vehicle's battery within a 5 hour period. If the system does not need this amount of power during this period, the access / reservation request may be rejected by the reservation management module (204) of the main manager (200), who may also suggest other parking conditions.

- the energy management module (202) of the main manager (200) can also update MAJ ALLOC P (S7) the power allocated to one or more charging stations (100), for example on the basis obtaining an update of an optimization proposal by a local manager (104) of a charging station.
- MAJ ALLOC P S7
- an indication of the power allocated to the charging station (100), determined and possibly updated by the energy management module (202) of the main manager (200) is then transmitted TRANS INDIC (S8), via the INT / LOCAL communication interface of the processing circuit CT of the main manager (200), to the INT / MAIN communication interface of the processing circuit CT of the local manager (104) of the charging station (100).
- This transmission can for example be carried out periodically.
- the local manager (104) thus obtains OBT INDIC (S9), an indication of the power allocated by the energy management module (202) of the main manager (200) to the charging station (100).
- the local manager (104) controls PILOT (S10) the charging terminals (102) on the basis of both the indication of the power allocated to the charging station ( 100) and the optimization proposal previously established by the local manager (104).
- the local manager (104) of a charging station (100) could order the autonomous vehicles which have completed their mission to change location, leaving the terminals load (102) free for other vehicles (106). This could improve the efficiency and profitability of parking and charging infrastructure.
- the management of reservations is a function intended to guarantee correct reservation of parking spaces.
- users can access any of the booking platforms, enter their charging requests, the period during which they want to use the service and whether they want their electric vehicle (EV) to be a seller or a buyer.
- the system must analyze, accept or reject the request, depending on the situation and the use case implemented, then inform the user of their fees / remuneration and conditions. general terms of the agreement.
- the user obtains proof of this transaction.
- the optimization zone places the vehicles in order of priority depending on the customer's subscription, the energy requested and the duration of parking.
- the access control interface is a function intended to offer the access control authority, in real time, the optimum location of the EV in the car park.
- the decision is transmitted to the reservation decision block. This block will ultimately inform the owner of the VE of the status of their request.
- the energy management is a function dedicated to the management of the energy transaction between all the electrical resources of the car park. This function aims to respect the power limit of the point of connection to the network, while ensuring customer satisfaction. To ensure proper management, the main manager (200) collects power measurements of all electrical resources, including the point of connection to the grid.
- the system collects the power / capacity demand of all electrical resources, the local load demand and the local discharge capacity at the level of the local managers (104) who are responsible for the energy transactions between electric vehicles connected to the same station.
- local management at level 1 indicates the priorities used for optimizing the powers allocated in order to guarantee maximum customer satisfaction and to optimize the use of the car park's electrical infrastructure.
- the optimization of the allocated powers induces the generation of power limit commands to the local managers (104) which condition the charge / discharge commands of the charging terminals (106).
- the optimization of energy management at level 2 (N2) has several objectives:
- Level 1 performs real-time management of the vehicles (106) (VE) connected to each charging terminal (102).
- Level 2 is responsible for centralized management at the car park level with a forecast management approach.
- Level 1 (N1) the local manager (104) aims to use all the power available in the charging station to meet the need for EVs as quickly as possible. In addition, if the EVs are sellers, the system must use its power to charge the EVs connected to the same terminal in the case of multiple outlet terminals or to supply power to the other terminals. To ensure this optimization, a weight system (w) is used. The weights of each VE are updated at each time step (5 or 10 minutes) by an auxiliary calculation or at level 2 (N2). [0134] Level 1 (N1) is responsible for the energy transaction between electric vehicles (“sellers” and “buyers”) and between the latter and other electrical resources. In addition, this level of management guarantees the satisfaction of requested requests for all connected electric vehicles.
- the local manager (104) contains a health check template that frequently checks the battery status of electric vehicles. This module checks the activation status of vehicles, battery status indicators (state of health (SoH) - state of charge (SoC)), charge / discharge capacity and other factors such as estimated departure time. These factors are then transformed into requests and priorities which are sent to the main manager (200) level 2 (N2). In addition, they are also used for the optimization of energy transactions as constraints to be observed in order to maintain an optimal energy transaction without damaging the batteries of electric vehicles. At this level of management, optimization has the following objectives:
- Level 1 (N1) can also record the charging behavior of electric vehicles in order to be able to transmit them to the main manager (200) so that the latter can subsequently use them in the parking space allocation function for a optimized distribution of the energy demand of electric vehicles distributed over different charging stations.
