Description
Technical field
The utility model relates to accumulator charging technology field, particularly relates to the equal floating charge timing of a kind of electric battery electrifier change-over circuit.
Background technology
Electric battery electrifier, in the time charging a battery, has and all fills and two kinds of charging modes of floating charge.Storage battery is in charging process, and along with cell voltage is full of gradually, charged electrical fails to be convened for lack of a quorum and reduces gradually, and charger selects all to fill operating state or floating charge operating state by detecting size of current.Generally speaking, in the time that charging current is greater than 2A, charger is in all filling state, and charging voltage is higher, and charging rate is very fast; In the time that charging current is less than 2A, charger is in floating charge state, and charging voltage is lower, can not cause damage to battery.
But some client is in charging the battery by charger, charger is also with other load current.In this case, the electric current that charger detects may be greater than 2A always, make charger always in all filling state, and even charging voltage is higher, and high voltage can cause damage to battery for a long time.
Utility model content
The purpose of this utility model is the deficiency in order to overcome above-mentioned background technology, and the equal floating charge timing of a kind of electric battery electrifier change-over circuit is provided, and can reduce the impaired probability of battery, improves battery reliability, improves battery, reduce spare parts cost.
The equal floating charge timing of a kind of electric battery electrifier change-over circuit that the utility model provides, comprise battery charge detection module, floating charge operational module, all fill operational module and the battery equal floating charge modular converter that charges, the charge signal input part of equal floating charge modular converter of the signal output part of described battery charge detection module and battery is connected, the charge first signal output of equal floating charge modular converter of described battery is connected with the signal input part that all fills operational module with floating charge operational module respectively with secondary signal output, also comprise instruction module and time judgment module, the charge signal input output end of equal floating charge modular converter of first signal input/output terminal and the battery of described instruction module is connected, the secondary signal input/output terminal of described instruction module is connected with the signal input output end of time judgment module.
The equal floating charge timing of the utility model electric battery electrifier change-over circuit, there is following beneficial effect: increase after instruction module and time judgment module, in the time being less than the electric current process battery charge detection module of 2A, battery charge detection module connects the battery equal floating charge modular converter that charges, charge equal floating charge modular converter of battery is connected floating charge operational module, makes charger in floating charge operating state.
When the electric current that is greater than 2A is during through battery charge detection module, battery charge detection module connects the battery equal floating charge modular converter that charges, and the battery equal floating charge modular converter that charges is connected and all filled operational module, makes charger in all filling operating state, meanwhile, the battery equal floating charge modular converter module that goes code of charging, instruction module simultaneously turn-on time judge module, time judgment module starts timing, when the charging interval is within 9 hours, signal is transferred to instruction module by time judgment module, instruction module by battery charge equal floating charge modular converter with all fill operational module keep be connected, make charger keep all filling operating state, exceed after 9 hours when the charging interval, signal is issued instruction module by time judgment module, instruction module sends signal to the battery equal floating charge modular converter that charges, charge equal floating charge modular converter of battery disconnects and all fills being connected of operational module, connect floating charge operational module simultaneously, force to be converted to floating charge operating state from the operating state of motor, avoid battery to cause damage.
Therefore, the utility model can reduce the impaired probability of battery, improves battery reliability, improves battery, reduce spare parts cost.
