The invention discloses a timing ending type pulse controlled floating charger, and belongs to the field of electronic technique. The timing ending type pulse controlled floating charger consists of atrickle resistor, a constant current unit, a charge unit, an interface unit, a pulse oscillating unit, a timing ending unit, a voice control unit, a load unit and a process indicating unit; the constant current unit is used for providing constant current for the charge unit, and thus constant current charging is realized; however, under the control of the interface unit, a charging and charging-stop pulse charging mode of the charging unit and the pulse oscillating unit is formed, and the charging time is longer than the charging-stop time, so that scientific charging for a charged battery isrealized, and the rejection rate is reduced; a timing ending type is adopted, a timer in the timing ending unit is low in static power consumption and wide in operating voltage range; after timing isended, the interface unit and the voice control unit are turned on, voice reminding is emitted while the charge unit is turned off, and simultaneously, the trickle resistor is used for providing sustaining trickle for the charged battery. The timing ending type pulse controlled floating charger is simple in circuit and easy to produce and debug, and is extremely applicable for microenterprise production.
