This invention describes a battery system where a single, removable battery pack can be used to power both a vehicle and a power tool. The battery pack has a special connection that allows it to electrically and mechanically link up with a port on the vehicle's power system and a port on the power tool. This means you could use the same battery for your electric car and your drill.
Why it matters: Advancements in high-power DC-DC conversion and smart battery management systems since 2023 could simplify adapting a single pack to vastly different power demands.
