A high voltage service disconnect assembly is provided. The battery pack has an enclosure, first and second battery modules, and positive and negative pack voltage terminals. The assembly includes a housing securing first and second conductive pins thereon. The first conductive pin is coupled to a negative voltage terminal of the first battery module. The second conductive pin is coupled to a positive voltage terminal of the second battery module. The assembly further includes a detection circuit electrically coupled to the first and second conductive pins. The detection circuit outputs a first isolation resistance fault signal when a first isolation resistance fault is detected between the negative pack voltage terminal and the enclosure.

An electric vehicle, such as an electric scooter, includes a seat that is adjustable for riding in a seated or leaning riding position. The electric vehicle also includes a removable battery pack that includes the controls for the vehicle. The electric vehicle also includes a storage tub with an expandable storage area depending upon the position of the seat.

An energy storage system includes a battery management system that has a plurality of loads connected in electrical series with one another, and a controller operatively connected to the plurality of loads. A first battery pack has battery cells connected in electrical series with respect to one another to establish a system voltage. The first battery pack is connected in electrical parallel to the plurality of loads. The controller is operable to balance charges of the battery cells by activating selected ones of the loads. The battery management system and the first battery pack are configured such that an additional battery pack with additional battery cells connected in electrical series with respect to one another or an additional load pack with additional loads connected in electrical series with respect to one another is connectable to the battery management system. A method of managing battery capacity is also provided.
