An adapter assembly including a power box that has a housing containing internal components, a longitudinal axis and a storage portion. The adapter assembly also includes a first cord coupled to and extending from the housing, an adapter including an engagement portion that is removably coupled to the storage portion of the housing and that selectively engages a power source-receiving portion of a tool, and a second cord having a first end coupled to the adapter and a second end coupled to the housing.

An external electric vehicle battery thermal management system is described. An electric vehicle thermal system provides external coolant to an internal battery thermal system of an electric vehicle. The internal battery thermal system includes a liquid-to-liquid heat exchanger to cool or warm the set of batteries of the electric vehicle. The external coolant is pumped through a first side of the heat exchanger and serves as the source to cool or heat internal coolant pumped through a second side of the heat exchanger. The external coolant and the internal coolant do not mix.

A charging connector includes a housing and a cover. The housing includes a normal fitting part and a quick fitting part. The normal fitting part has a normal frontage to which a normal charging connector is finable. The quick fitting part has a quick frontage to which a quick charging connector is finable. The cover is configured to close the quick frontage. The quick fitting part has a terminal insertion hole through which a terminal of the quick charging connector is insertable inside the quick fitting part. The cover has a first protrusion extending toward the terminal insertion hole and holding the cover on the housing with the first protrusion being inserted into the terminal insertion hole.

A power receptacle assembly includes a base unit which includes a housing. The housing includes a bottom housing, a housing cover coupled to the bottom housing and first and second end caps coupled to the bottom housing and the housing cover. The bottom housing, the housing cover, and the first and second end caps define a housing interior. The base unit also includes a constant voltage driver disposed within the housing interior. Additionally, the power receptacle assembly includes a plurality of power receptacles electronically coupled to the constant voltage driver though the housing. The power receptacle assembly also a secondary unit including a housing defining an interior, a sled coupled to another power receptacle configured to be disposed within the housing interior and a clamp.

An electric connecting device includes an insulator with a front end abutting surface and a rear end mounting surface, a terminal module and a USB plugging module in the insulator. A first plugging cavity and a second plugging cavity distributed in a horizontal direction and a guide hole between them are arranged in the insulator. The first plugging cavity and the second plugging cavity forwardly penetrate through the front end abutting surface and form a round interface and a USB interface respectively. By simultaneously providing the two plugging cavities on the insulator, two different plugging functions can be satisfied. The transmission of a DC power supply and the transmission of a USB signal are realized at the same time. The integrated structure can reduce the occupation of a circuit board space and the assembly cost of the product.
