Hybrid Battery Pack Deterioration

Dtc p0a7f hybrid battery pack deterioration circuit description the battery ecu calculates the soc state of charge of the hv battery by estimating the amperage that flows into the hv bat tery and monitoring other values.

Hybrid battery pack deterioration.

Hybrid cars incorporate amazing technology to achieve better fuel mileage but over time the batteries can begin to deteriorate. The driving cycle of a hybrid vehicle subjects the battery pack to repeated shallow depths of discharge of less than 10 of the battery capacity. Longevity performance and warranty. The truth is toyota hybrids can run almost 180 000 miles without showing any sign of deterioration.

Since the hybrid battery is made up of all these smaller modules it is very common for them to deteriorate at different rates this uneven deterioration results in an unbalanced battery pack and. The battery is carefully discharged well below the level that the vehicle would allow during normal operation. This is generally detected by inconsistent battery temperatures and voltages. This is a generic diagnostic trouble code dtc and applies to many obd ii vehicles 1996 newer.

The hv control ecu charge and discharge depending on. Lithium battery pack for your hybrid. Then the power management. As your vehicle gets older fuel mileage may decline a good indicator of a battery that s gone bad.

What does that mean. Honda hybrid batteries are designed to perform at least 10 years under normal driving conditions. Then a hybrid battery discharger is connected to the battery to provide load that discharges the battery. Lithium battery packs outperform nimh in every category.

The unused capacity undergoes a correctable degradation process that reduces battery capacity. Hybrid battery pack deterioration. That may include but is not limited to vehicles from honda accord civic insight toyota prius camry lexus etc. Both brands along with ford offer an 8 year warranty or minimum 80 000 miles whichever comes first for their hybrid battery packs.

The hybrid battery reconditioning process is performed by first charging balancing the battery pack with a hybrid battery charger. Hybrid battery pack deterioration description the battery smart unit and the power management control ecu calculate the soc state of charge of the hv battery through the accumulated amperage in the hv battery. P0a7f hybrid battery pack deterioration this code often means that your vehicle s pcm power control module has detected an excessive degree of resistance or that there is insufficient state of charge from your hybrid vehicle s high voltage battery pack. The battery ecu sends the calculated soc to the hv control ecu.
