Disclosed herein are battery management systems and methods for activating battery override logic for a battery management system to provide a power path to a battery pack. A method of activating battery override logic for a battery management system may comprise detecting a predetermined key toggle sequence performed in a predetermined amount of time or detecting an override message received from a CAN bus. The method may further comprise determining if the last override turn-on sequence was requested more than a predetermined amount of time ago, confirming that the override is configured for the contactor, and turning on the contactor to provide a power path to the battery pack for a limited predetermined amount of time. An exemplary predetermined toggle sequence may comprise on-off-on-off-on performed within 10 seconds. An exemplary override message from the CAN bus may be initiated by a user having a key, code, or access card.
