**********************************************************************************
Żywotności nie sprawdzałem, oni Niemcom piszą (sprawdźcie linki poniżej), że to 15 tys. cykli w co nie wierzę, ale te ogniwa spokojnie wytrzymują 3-4 tysiące cykli bez znaczącej utraty pojemności, czyli minimum 10 lat codziennego ładowania i rozładowywania.

Wyniki testów pokazanych w filmie:

Bateria 1
Ładowanie, pobrała 2,957 kWh
Rozładowanie, oddała 2,698 kWh
Sprawność aż 91%

Bateria 2
Ładowanie, pobrała 2,950 kWh
Rozładowanie, oddała 2,633 kWh
Sprawność 89%

Szeregowo Bateria 1 + Bateria 2
Ładowanie, pobrała 5,956 kWh
Rozładowanie, oddała 5,408 kWh
Sprawność aż 91%

Ładowałem i rozładowywałem do pełna, aż zabezpieczanie w bateriach BMS zadziałał.
Maksymalny prąd 160A (falownik się wyłączył nie akumulator)

Temat: Badanie akumulatorów LiFePO4 firmy Li Time LFP

Prąd ładowania ca.20A , rozładowania ca.15A

Li Time 1 – wyładowanie do końca.
Napięcie –10,82V na watomierzu DC, 10,7V 0% na BcV
Wh -2.698 Wh na watomierzu DC, (2.294 Wh na watomierzu AC po falowniku)

Li Time 2 – wyładowanie do końca
Napięcie – 11,15V na watomierzu DC, 11,0V 0% na BcV
Wh – 2.633 Wh na watomierzu DC, (2.241 Wh na watomierzu AC po falowniku)

Li Time 1 – ładowanie do pełna
Napięcie -13,74V
Wh 2.957 Wh na watomierzu DC (AC gniazdko 3.734 Wh razem z ładowarką)

Li Time 2 – ładowanie do pełna
Napięcie -13,76 V
Wh 2.950Wh (5.907 – 2.957)na wat. DC (AC gniazdko 3.749 Wh razem z ładowarką)

Li Time 1 + Li Time2 – wyładowanie do końca
Wh (łącznie) –5.408 Wh (AC gniazdko po przetworniku 4.835 Wh)
Napięcie Li Time 1 -11,24 V
Napięcie Li Time 2 -11,51 V

Li Time 1 + Li Time2 – ładowanie do pełna
Wh (łącznie) 5.956 Wh (AC gniazdko 6.829 Wh)
Napięcie Li Time 1 + Li Time 2 -28,66 V

Akumulator 1 – Rozładowanie 2.698Wh (ładowanie 2.957Wh) = 91 %
Akumulator 2 – Rozładowanie 2.633Wh (ładowanie 2.950Wh) = 89%

Ładowanie 2.957 + 2.950 = 5.907 Wh
Rozładowanie 5.408 Wh
91,5%

Straty
Ładowarka 3,734 kWh – 2,957 kWh = 0,777 kWh pobrała ładowarka
Rozładowanie 2,698 kWh – 2,294 kWh = 0,404 kWh pobrała przetwornica

DC do DC 2,957 kWh – 2,698 kWh = 0,259 Wh utracono (sprawność 91%)
AC do AC = 3,734 kWh – 2,294 kWh = 1,440 kWh utracono (sprawność 61%)
