Abstract

A charging system with an enhanced charging efficiency has two connectors each having multiple connection points, which are connected between multiple chargers and multiple rechargeable batteries. The chargers are connected to one of the connectors through multiple first connection wire sets. The other connector is connected to the rechargeable batteries through multiple second connection wire sets. Output terminals of the chargers and the positive and negative terminals of the rechargeable batteries are respectively connected to the connectors. Thus, the chargers receive power through a power input port and output power converted thereby to the rechargeable batteries through single-port connection of the connectors in a one-to-one fashion to achieve the purpose of simultaneously and efficiently charging multiple rechargeable batteries and providing operational convenience because of the easy and convenient connection of the connectors.
