摘要： A charger includes a housing with an interface positioned in a front wall and configured to engage a battery pack. The interface includes charging terminals positioned between a first rail and a second rail, a first groove positioned between the first rail and a wall of the housing, and a second groove positioned between the second rail and the wall of the housing. The interface is in communication with an interior of the housing. A fan is coupled within the housing adjacent the interface, and an air passage member includes a hollow body that has a first end coupled to the fan and a second end spaced apart from the first end extending through another wall of the housing. The fan is operable to suck an air flow into the housing from outside the housing and guide the air flow through the air passage member to the interface.

摘要： 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.
