Claims

[Scope of utility model registration request]

(1) In a device in which a battery to be charged is connected between the charging line output terminals of a charger for charging, the charging line output terminals of the charger are shared between positive and negative terminals, and at least one of the batteries to be charged is connected between the charging line output terminals of the charger. An element that provides directionality of current flow is inserted into the charging line, and different types of batteries to be charged are charged depending on whether the batteries to be charged are connected in either the forward or reverse direction between the charging line output terminals of the charger. A charging circuit made like this.

(2) Utility Model Registration Scope of Claim 1 In the charger's positive line, a resistor and a positive diode are coupled in series, and the negative line is a resistor and a reverse diode coupled in series, A charging circuit in which these positive and negative lines are connected to one charging line output terminal in parallel with each other.

(3) Utility Model Registration Claims Claim 1 has at least two types of chargers, and one output terminal has a positive direction line of one charger and a negative direction line of the other charger. and connect the negative direction line of one charger and the positive direction line of the other charger to the other output terminal,
Insert a switch into the positive line of each charger,
The charging circuit consists of turning these switches on and off alternately.
