jeep Wrangler Rubicon Hydrid 2022. Не заряжается батарея от ДВС

[Мастак]

Предыстория: машина куплена после ДТП в заднюю часть авто и восстановлена. Оригинальный пробег 6000км.

После ремонта обнаружили, что авто от батареи умеет ехать не более нескольких сотен метров, от ДВС больше 1% не заряжается. Попробовали зарядить от розетки - всё ок, зарядилась и ездила до полной разрядки батареи.

По ошибкам после включения зажигания появляются и не стираются 2 неисправности:

1. P0ABC-00 Низкое напряжение цепи датчика напряжения гибридной аккумуляторной батареи

2. P0AA6-00 нарушение изоляции высокого напряжения

Работаю с машиной с помощью АлфаОБД. Тест изоляции батареи показывает чуть более 2 мегаома, что является нормой судя по мануалу. 

Подскажите кто поопытнее в какую сторону копать, что смотреть? С гибридами опыта мало.

Судя по параметрам генератор работает адекватно и заряд на батарею даёт. Если в тестах отключить гибридную АКБ ошибки не выскакивают.

Всевозможные тесты, адаптации, удаления краша и т.д. в меню Альфы сделал, но результата 0

P0AA6-00-HYBRID BATTERY VOLTAGE SYSTEM ISOLATION FAULT

For a complete HIGH VOLTAGE DISTRIBUTION SYSTEM wiring diagram, (refer to the Wiring Information).

Theory of Operation

The Battery Pack Control Module (BPCM) is contained within the High Voltage Battery Pack. The BPCM provides battery management and system functionality in conjunction with Cell Supervision Circuits (CSCs) that monitor and balance the battery cells as well as the monitoring of related external support systems. The CSCs are also located within the High Voltage Battery Pack. The BPCM is the High Voltage Interlock (HVIL) power source and communicates with the vehicle via CAN-C bus. The main functions of the BPCM are high-voltage bus and pre-charge contactor control, battery pack current, voltage and temperature sensing, CAN communication, fault detection and reporting. Diagnosing any DTC related to the BPCM should start with verifying that all fuses, wiring and connections critical to proper system operations are in good repair, securely installed and connected.

When Monitored and Set Conditions

When Monitored:

This diagnostic runs periodically when the following conditions are met:

Ignition on and the contactors are closed.

Set Conditions:

This DTC will set if the Battery Pack Control Module detects that any High Voltage component or cable has developed an isolation failure.

Default Actions:

Malfunction Indicator Lamp (MIL) on.

HEV warning lamp on.

Possible Causes

ANY HIGH VOLTAGE COMPONENT OR CABLE THAT HAS LOST ISOLATION

ANY HIGH VOLTAGE COMPONENT INTERNALLY SHORTED

BATTERY PACK CONTROL MODULE (BPCM)

WARNING

On vehicles equipped with the high voltage system, you must thoroughly read and follow all High Voltage Safety procedures. In addition, before performing any diagnostic or service procedure near a high voltage component, you must perform the High Voltage Power Down. Failure to follow these instructions may result in possible serious or fatal injury.

Always power down the High Voltage System before performing diagnostic tests or repairs to the High Voltage system. (Refer to Electrified Powertrain System/Electric Powertrain Control/Standard Procedure).

Always perform the Pre-Diagnostic Troubleshooting procedure before proceeding. (Refer to Refer to 28 - DTC-Based Diagnostics/MODULE, Battery Pack Control (BPCM)/Standard Procedure).

Я по ним и пытался разобраться, но упираюсь в вариант "Replace the High Voltage Battery Pack". Как-то не готов я рискнуть приговорить батарею без 100% уверенности. Смущает, что батарейка от розетки адекватно заряжается.

Завтра буду у авто и выложу скрины с параметрами на заведенном моторе. Планирую разбирать зад машины и добираться до батареи.

[поднявшийся спящий]

Гораздо выше должно быть сопротивление. Она пишет 2 ошибки вполне конкретные. Даже по одной из них не будет заряда. 

[Мастак]

3 часа назад, поднявшийся спящий сказал:

В мануале 2.3. Вы уверены, что должно быть больше?

В мануале 2.3. Вы уверены, что должно быть больше?

Именно с американцем гибридом не возился но по опыту других авто ошибку по сопротивлению вываливает даже на 6Мом. А в среднем там 50МОм

Мануал именно по этой машине у вас? Странно, у вас по мануалу сопротивление в допуске а ошибка есть............

[Мастак]

26 минут назад, поднявшийся спящий сказал:

Мануал именно по этой машине у вас?

Да, именно этот автомобиль с этим гибридом и этого года.

Вот основные параметры при заведённом двс

 

[поднявшийся спящий]

Я на вашем месте начал бы с ошибки напряжения 

[Мастак]

Оказалось, что альфа неверно показывает сопротивление изоляции. При фактическом замере мультиметр показал 0.13МОм. 

Причина - кто-то при ремонте кузова вкрутил не тот болт (более длинный) в крепление защиты инвертора тем самым продавив корпус. Вкрутил нормальный болт, сопротивление возросло до 2.4 МОм. После стирания ошибок гибрид ожил.

Всем спасибо за помощь!
