Embodiment Construction

[0023] see figure 1 , shows a protected system for controlling the electricity transaction of an electric vehicle 2 according to the invention. The electric vehicle 2 is equipped with a case 4 containing a battery 6 , a battery management system 8 , a vehicle management unit 10 , and a bus 12 between the vehicle management unit 10 and the battery management system 8 . The electric vehicle 2 has other components or devices specific to its use and its operation, like the dashboard 14 and an electric motor controller 16 connected to the bus 12 . The electric vehicle 2 may also be equipped with a charger 18 or another device like a computer 24 coupled between the bus 12 and an external connection element 20 that allows the electric vehicle 2 to be connected to a charging station 22, with the electrical network 26 or A connection to another power source or an external charger 28 (if the electric vehicle 2 does not have an integrated charger).

Abstract

The present invention relates to a protected system for controlling electricity transactions of electric vehicles. Identification modules are incorporated into the battery management system and box of the vehicle, and integrity sensors of the box and battery are connected to a monitoring module. The system includes a processing module for processing information generated by the battery management system, vehicle management unit, integrity monitoring module, and an identification module for identifying devices connected to the bus and located between the devices. generated information. A memory stores data indicative of the technical characteristics of the battery as well as event, transaction and energy data depending on the information received. A computing unit determines an energy balance based on the event, transaction and energy data. A communication module sends an alert in the event of an imbalance in the energy balance and integrity violations revealed by the data.

Description

technical field [0001] The invention relates to a battery management system for an electric vehicle. More precisely, the invention relates to a protected system for controlling the electricity transaction with the battery management system of an electric vehicle, allowing inter alia to monitor the integrity of the energy system of the electric vehicle and to detect energy theft. Background technique [0002] The shift from non-renewable to renewable energies will have implications for the taxation of these energies. Greater population adoption of electric vehicles in the medium term will lead to recurring energy theft problems for utilities. For the user, this will involve ensuring that data about the health of the battery, the battery itself, its case and its management system has integrity and has not been tampered with. [0003] Electric vehicles have a battery management system ("BMS"). The function of the BMS is generally to protect the battery cells of the battery, ...
