Abstract: 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.

Abstract: A method and a system for awarding an instant rebate are provided. The method comprises: determining a price for each item of a purchase of at least one item made by a client; selecting at least one item of the purchase using the nature of the item, the price determined, a price for a plurality of item and/or a total price for the purchase; activating a random rebate generator using the item selected to determine if an amount proportional to the price determined is to be awarded to the client; calculating an altered price by reducing the price determined by the proportional amount if the proportional amount is to be awarded; carrying out a payment of the altered price by the client.
