  • Publication number: 20240067041
    Abstract: A portable battery device for a mobility apparatus and a battery management system and a method, which are capable of securing a desired range of the mobility apparatus by selectively adding an auxiliary battery in a situation in which a battery capacity should be additionally supplemented, are disclosed. The auxiliary battery is stored in the mobility apparatus or is supplied from an external supply source when the auxiliary battery is commercially available. Accordingly, electric power supply to the mobility apparatus becomes convenient. The auxiliary battery is simply replaceable through separation or mounting thereof from or in a case at an outside of the mobility apparatus. Accordingly, handling convenience of the auxiliary battery is enhanced. When collision of the mobility apparatus occurs, the auxiliary battery is separated due to impact and, as such, generation of fire caused by damage to the auxiliary battery is prevented and stability is secured.
