Yes, a bad car battery can trigger the check engine light.
Around 4-5 weeks ago the car started to develop a fault around the HV battery and would continually complain that an electrical fault had occurred but it was "safe to drive with caution". Hoping that it would stop and go away (it didn''t), it started to refuse charging via my home type 2 7kw/h, we tried two cables but no luck.

Free QuoteCommon fault codes associated with a bad battery include P0562, P0563, P0720, and U0100. Understanding these fault codes entails reviewing how they connect to battery issues. Fault codes often indicate problems in the vehicle's electrical system, which can result from a bad battery. Let's explore each code more specifically.
The car battery warning light illuminates on the dashboard when the ECU detects a problem with the battery unit or its charging system. It may indicate a low voltage, resulting from a damaged, corroded or worn battery, or a damaged alternator, for example. Keep reading for more information on what different battery indicator lights mean.
A flat or failing battery – if the battery can't hold its charge properly, it may trigger the warning light. Loose or corroded battery terminals – this can interrupt the flow of electricity. A damaged drive belt – if the car serpentine belt that drives the alternator is loose, worn, or broken, the alternator can't recharge the battery.
Yes, a bad battery can trigger fault codes in a vehicle. The car's computer detects low voltage from sensors. This can result in various error codes. The effect varies by car make and model. After replacing the battery, resetting the ECU may be necessary for proper functioning.
The check engine light will often turn on when you jump a dead battery. Your vehicle's computer is warning you the system is at low voltage. Without a strong voltage supply, the computer will no longer function properly. If your battery voltage is low, the computer will be starved of voltage, enabling the check engine lights.
This is probably the most common cause of the battery charge fault. Over time, batteries can get damaged, the terminals become corroded, or the cables get dislodged or damaged. If this happens, the battery will no longer be able to hold the charge from the alternator and gradually lose power over time.
