  • e is an electrolyte solution disposed between the anode and the cathode, and an alkaline aqueous solution is used here.
  • g shows the envelope which accommodates them.
  • the battery in the second region has a high voltage (1.8 V to 3.0 V per cell): high capacity and high energy density.
  • the battery has a high energy density, and the energy density of the separated lead-free battery is several times higher than that of the lead battery. Therefore, reduction in size and weight can be realized.
  • FIG. 7 is a charge / discharge characteristic comparison diagram, which compares the conventional lead battery and a non-cathode-separated lead-free battery with the measured values of the cathode-separated high-energy density lead-free battery of the present invention. Both curves are compared in the case of 40 Ah capacity.
  • (A) is a diagram comparing the charging characteristics, the high capacity type indicates a cathode-separated lead-free battery, and the non-separable type indicates a cathode-free battery (a paste in which zinc and carbon are mixed). .
  • the capacity is 40 Ah and the time difference from 10.8V to 12.5V is shown.
  • a separate type high capacity density lead-free battery (high capacity type) has a very short charging time compared to other non-separated type lead batteries.
  • (B) is the figure which compared the discharge characteristic, and a high capacity
  • the cathode separation type is 7.2H
  • the non-separation type lead-free is 3.5H
  • the lead battery is 2.2H
  • the cathode separation type free battery shows that the discharge characteristics are also larger than others.
  • the above charge / discharge characteristics are greatly advantageous when the vehicle hybrid system is divided into two groups and is charged and discharged alternately.
  • FIG. 8 is a table showing how the capacity of the cathode electrode material separation type lead-free battery (high capacity) increases with respect to the lead-free battery (lead-free) and lead batteries A and B which are not separation type. It can be seen that the cathode separation type (high capacity) increases about twice as compared with the case where no separation is performed.
  • the pattern period N per unit length becomes closer to the characteristics of the non-separable lead-free battery, so it is meaningless to make the pattern period N too large.

Abstract

La présente invention concerne un système hybride économique carburant pour véhicules, qui utilise des batteries haute capacité haute densité comme piles secondaires pour entraîner les moteurs de roues utilisés dans le système hybride de véhicule, réduit la charge sur le moteur et augmente la charge dans les batteries. La présente invention concerne également un système hybride utilisant des batteries sans plomb écologiques. L’économie de carburant est amenée à au moins 70 km/l grâce à une unité d’entraînement des roues avant pour la puissance du moteur et une unité d’entraînement des roues arrière pour la puissance des moteurs de roues alimentés par les batteries; à l’alimentation des moteurs à l’aide de batteries haute performance capables de fournir un équilibre avec la charge du moteur; et à l’utilisation du moteur en cas de besoin temporaire de puissance comme pour les accélérations rapides et les montées, tandis que les batteries sont utilisées à basses vitesses en ville et à grandes vitesses pour les trajets de longue durée. La commutation entre la puissance moteur et la puissance batterie se fait notamment au moyen des modes conduite et neutre du changement de vitesse, un programme informatique de dispositif de commande permettant de rendre le système hybride plus efficace.
