Description
これにより、電気自動車10が走行する。なお、DCDCコンバータ14は、容量型電池15の電圧を、インバータ12やモータジェネレータ11の動作電圧まで昇圧あるいは降圧する。
すなわち、本実施例1においては、一個のパワー型電池の電圧範囲を直列数倍した電圧範囲、すなわちパワー型電池の直列接続の電圧範囲が、モータの電圧範囲の全てをカバーする。
例えば、パワー型電池としてリチウムイオンキャパシタを用い、電圧範囲は一個当たり2.2V(SOC0%)から3.8V(SOC100%)、直列数は90個とする。また、容量型電池として、リチウムイオン半固体電池を用い、電圧範囲は一個当たり3.0V(SOC0%)から4.2V(SOC100%)、直列数は80個とする。この例では、直列接続の電圧範囲は、パワー型電池(リチウムイオンキャパシタ)では198Vから342Vとなり、容量型電池(リチウムイオン半固体電池)では240Vから336Vとなる。従って、式(2)を満たす。この場合には容量型電池のSOCは0%から100%まで使える。そしてパワー型電池のSOCは29.1%から95.8%の間となる。このように、電池出力を確保しながらも電池容量を高めることができる。
また、容量型電池のSOC範囲が制限されている場合も同様である。
