Abstract

Disclosed herein is a battery management system. A housing may contain one or more of an electric motor, a battery electrically coupled to the electric motor, and a sensor configured to detect a harmful environmental condition within the housing. Such sensors can detect a potentially harmful condition including but not limited to smoke, heat, water, or shock. A circuit may be coupled to the at least one sensor and configured to uncouple the battery from the motor and discharge the battery when the sensor detects the harmful environmental condition. If a potential problem with the internal environment of the cassette is detected, the cassette batteries can be effectively disconnected with the main output, thus disabling the motors. Furthermore, energy stored in the batteries can be slowly and safely discharged. In some embodiments, when a potential problem with the internal environment of the cassette is detected, the batteries can be discharged and permanently disabled. Illustrative embodiments disclose a battery management system implemented in a motorized watercraft.
