当初は、補助電池20によって主電池10を充電している。
ステップ1(図2においては「S1」と略記する。以下同様。):補助電池20の出力電力をW、その閾値をW1としたとき、補助電池20の出力電力Wが、閾値W1よりも大きいか否かを判定し、その補助電池20の出力電力Wが閾値W1よりも大きいと判定されればステップ4に進み、そうでなければステップ2に進む。
Initially, the main battery 10 is charged by the auxiliary battery 20.
Step 1 (abbreviated as “S1” in FIG. 2. The same applies hereinafter): When the output power of the auxiliary battery 20 is W and the threshold value is W1, the output power W of the auxiliary battery 20 is larger than the threshold value W1. If it is determined that the output power W of the auxiliary battery 20 is greater than the threshold value W1, the process proceeds to step 4. Otherwise, the process proceeds to step 2.

ステップ2:補助電池20の出力電力が不足しているので、電圧変換・経路切り替え部30を介して、補助電池20から主電池10への充電経路aから、その補助電池20から蓄電池15への充電経路bに切り替える。すなわち、補助電池20による蓄電池15への充電を開始してステップ3に進む。   Step 2: Since the output power of the auxiliary battery 20 is insufficient, the voltage from the auxiliary battery 20 to the storage battery 15 is changed from the auxiliary battery 20 to the main battery 10 via the voltage conversion / path switching unit 30. Switch to charging path b. That is, charging of the storage battery 15 by the auxiliary battery 20 is started and the process proceeds to step 3.

ステップ3:蓄電池15の充電率(SOC(State Of Charge))をW2、その閾値をW3としたときに、閾値W3よりも充電率W2が小さいか否かを判定し、閾値W3よりも充電率W2が小さいと判定したときには、ステップ3を繰り返し、そうでなければ処理(充電動作)を終了する。これにより、蓄電池15への過充電を防止できる。   Step 3: When the charging rate (SOC (State Of Charge)) of the storage battery 15 is W2 and its threshold is W3, it is determined whether or not the charging rate W2 is smaller than the threshold W3, and the charging rate is lower than the threshold W3. If it is determined that W2 is small, step 3 is repeated, otherwise the process (charging operation) is terminated. Thereby, the overcharge to the storage battery 15 can be prevented.

ステップ4:主電池10の充電率をX1、その充電率の閾値をX2としたときに、充電率X1が閾値X2よりも小さいか否かを判定し、充電率X1が閾値X2よりも小さいと判定されればステップ1に戻り、そうでなければステップ5に進む。これにより、主電池10への過充電を防止できる。   Step 4: When the charging rate of the main battery 10 is X1 and the threshold of the charging rate is X2, it is determined whether or not the charging rate X1 is smaller than the threshold X2, and if the charging rate X1 is smaller than the threshold X2 If it is determined, the process returns to Step 1; otherwise, the process proceeds to Step 5. Thereby, the overcharge to the main battery 10 can be prevented.

ステップ5:電圧変換・経路切り替え部30を介して、補助電池20から主電池10への充電経路aから、その補助電池20から蓄電池15への充電経路bに切り替えて、ステップ6に進む。   Step 5: The charging path a from the auxiliary battery 20 to the main battery 10 is switched to the charging path b from the auxiliary battery 20 to the storage battery 15 via the voltage conversion / path switching unit 30, and the process proceeds to Step 6.

ステップ6:蓄電池15の充電率をW2、その閾値をW3としたときに、充電率W2が閾値W3よりも小さいか否かを判定し、充電率W2が閾値W3よりも小さければステップ7に進み、そうでなければ処理を終了する。これにより、蓄電池15への過充電を防止できる。   Step 6: When the charging rate of the storage battery 15 is W2 and the threshold is W3, it is determined whether or not the charging rate W2 is smaller than the threshold W3. If the charging rate W2 is smaller than the threshold W3, the process proceeds to Step 7. Otherwise, the process ends. Thereby, the overcharge to the storage battery 15 can be prevented.

ステップ7:主電池10の上記充電率X1が閾値X2よりも小さいか否かを判定し、充電率X1が閾値X2よりも小さいと判定されればステップ6に戻り、そうでなければステップ1に進む。これにより、主電池10への補充電(再充電)を行う。   Step 7: It is determined whether or not the charging rate X1 of the main battery 10 is smaller than the threshold value X2. If it is determined that the charging rate X1 is smaller than the threshold value X2, the process returns to Step 6. Otherwise, the process returns to Step 1. move on. Thereby, the auxiliary charge (recharge) to the main battery 10 is performed.
