  • Electric vehicles in the form of passenger cars have recently come into production by certain automobile manufacturers.

  • the handshaking sequence is facilitated by a microprocessor in the EVSE and another microprocessor of the on-board battery management system in the EV. Both microprocessors contain firmware enabling them to perform this function.
  • the handshaking sequence or protocol enables either the EV or the EVSE to suspend operation if either one detects a fault or unacceptable condition in the other.
  • the time required to fully charge the EV on-board battery pack is determined by the voltage and current level of the power supplied by the EVSE. It is desirable to minimize this charging time, and for that reason the charging current is maintained at the highest practical level. This level may be in accordance with. Table 1 of SAE J1772, which defines allowable current levels for different nominal supply voltages of the utility. For example, for a nominal supply voltage of single phase 120 VAC, the maximum allowable charging current that can be drawn from the EVSE by the EV is 12 A using a 15 A circuit breaker or 16 A using a 20 A circuit breaker. For a nominal supply voltage of 240 VAC, the maximum allowable current may be as high as 80 A, depending upon the current ratings of the components employed.

Abstract

Le système d'alimentation pour véhicule électrique (EVSE) ci-décrit évite l'interruption du chargement en raison d'une surchauffe grâce à un ajustement du cycle d'utilisation des impulsions sur le conducteur pilote communiquant au véhicule électrique le niveau d'intensité du courant maximum admissible, cet ajustement étant réalisé à chaque fois que la température de l'EVSE dépasse un seuil de température prédéfini inférieur à la température de fonctionnement maximale lorsque la température se rapproche de la température de fonctionnement maximale.
