Protected system for controlling power transactions for an electric vehicle

摘要

The invention concerns a protected system for controlling power transactions for an electric vehicle. Identification modules are incorporated into the vehicle battery management system and box, and integrity sensors of the box and of the battery are connected to a monitoring module. The system comprises a processing module for processing information produced by the battery management system, the vehicle management unit, the integrity monitoring module, and an identification module for identifying devices connected to a bus between the devices. A memory stores data indicative of technical characteristics of the battery, and data concerning events, transactions and energy depending on the information received. A calculation unit determines an energy balance according to the event, transaction and energy data. A communication module transmits a warning in case of an imbalance in the energy balance and a breach in integrity revealed by the data.

主权项

1. A protected system for controlling power transactions for an electric vehicle provided with a box enclosing a battery, a battery management system, a vehicle management unit, and a bus between the vehicle management unit and the battery management system, the protected system comprising:
identification modules respectively integrated to the box and the battery management system, providing identification information of the box and the battery management system; a set of integrity sensors of the box and of the battery having readable states; an integrity monitoring module connected to the integrity sensors, producing information indicative of the states of the integrity sensors; a device identification module for identification of devices connected to the bus; a processing module for processing device information produced by the battery management system, the vehicle management unit, the integrity monitoring module, the device identification module and other given devices when connected to the bus, the processing module having:
a memory storing data indicative of technical characteristics of the battery, and event, transaction and energy data derived from selectively processing the device information as a function of the technical characteristics of the battery; anda calculation unit determining an energy balance as a function of the event, transaction and energy data; and a communication module having a mode of transmission of a warning in case of an imbalance in the energy balance and in case of an integrity breach revealed by the data stored in the memory of the processing module.
