The automatic floating charger of a generator set storage battery comprises a pulse width modulation module; the signal output end of the pulse width modulation module is respectively and electrically connected with an output current regulation module and an output voltage regulation module; the signal input end of the pulse width modulation module is respectively and electrically connected with a current control module, a voltage control module and a current sampling module; and the signal input end of the current control module and the voltage control module is electrically connected with signal output end of a voltage converter module respectively by a rectifier filtering module. The utility model has the advantages that the charger charges according to the charging characteristics of the storage battery and adopts a two-stage charging method; the charging mode is 'constant current variation', and no harm is caused for storage batteries if the storage batteries are charged for a long time, i.e. the charger can maintain the filling state of the storage batteries and can ensure the service life of the storage battery.
Description
Technical field
The utility model relates to charger, especially relates to the automatic floating charge device of a kind of generating set storage battery.
Background technology
The automatic floating charge device of present generating set does not all adopt the automatic charging modes of constant current constant voltage, and lead acid accumulator is easy to overcharge, and shortened its useful life, has improved use cost.
The utility model content
The purpose of this utility model is to provide a kind of automatic floating charge device of generating set storage battery that prevents that lead acid accumulator from overcharging.
For achieving the above object, the utility model can be taked following technical proposals:
The automatic floating charge device of generating set storage battery described in the utility model, it comprises the pulse width modulation module, the signal output part of described pulse width modulation module is electrically connected with output current adjustment module and output voltage adjustment module respectively; The signal input part of described pulse width modulation module is electrically connected with the signal output part of current control module, voltage control module and current sampling module respectively; Described current control module is electrically connected by the signal output part of rectification filtering module with the voltage transformation module respectively with the signal input part of voltage control module.
The utility model advantage is to charge according to the charge in batteries characteristic, adopts the two-stage mise-a-la-masse method, and charge mode is " a permanent flow-changeable ", promptly before the terminal voltage of storage battery is lower than preset value, is charged as constant current charge; After the terminal voltage of storage battery is higher than preset value, charging current raises with the terminal voltage of storage battery and reduces gradually, after reaching the predetermined current value, charging transfers the floating charge pattern to, at this moment charging current reduces gradually, battery terminal voltage also raises gradually and reaches default constant voltage value, when charging current during less than 0.3A battery be full of (charging indicator light goes out) substantially, after this charging current is only offset the self discharge of storage battery, and long-time charging is also harmless to battery, be the full state that charger both can have been kept storage battery, the useful life that can guarantee storage battery again.
