Abstract
A liquid crystal display intelligent charger of electrocars relates to the technical field of the charger of electric vehicles or electric bicycles, wherein one end of a rectifier filter is connected with utility power, the other end thereof is connected with a high frequency reduction transformer, the output end of the high frequency reduction transformer is connected with another rectifier filter, the output end of the rectifier filter is connected with a charging display circuit and a current charging circuit, the current charging circuit is connected with a voltage detection circuit and a current detection circuit, the output end of the voltage detection circuit is connected with the charging display circuit and a feedback control circuit, the current detection circuit is connected with the feedback control circuit, and the feedback control circuit is connected with the high frequency reduction transformer through a pulse width modulation control circuit and a power drive circuit. The utility model can be used with the existing various lead-acid cells and lithium cells which are in charging, so two series of display without backlight and display with backlight are generated, the electricity loss degree of batteries can be obtained, the time for charging can be mastered, and the battery is ensured not to be overcharged when the voltage of all the sections of a battery pack is not balanced.
Description
Technical field
The utility model relates to electric automobile or electric bicycle technical field, particularly its charger technical field.
Background technology
Whether the electric car charger of selling on the market has generally adopted red and green luminous pipe to come pilot cell to be full of: to charge when sending out a warning, be full of when giving a green light now.This product exists many defectives to make people have all inconveniences when using these products.
At first be the progress that this charger can't be judged charging, make the user can't determine when battery can be used, make troubles for user's daily use.
Charger can't be judged this state when contact bad (charger is actual at this moment is unloaded) secondly in use occurring.
This besides charger function is perfect inadequately, when battery produces each single battery Voltage unbalance in use for some time, and the phenomenon do not changed with the easy appearance of charger of old back of battery, in case occur not changing very easily not filling bulging battery.
The utility model content
The utility model purpose is the liquid crystal display charger into the supporting a kind of demonstration charge volume directly perceived of electric motor car.
The utility model comprises the rectifier filter that is electrically connected with the city, the other end at described rectifier filter connects the high frequency voltage descending transformer, the output of described high frequency voltage descending transformer connects another rectifier filter, the output of described rectifier filter connects charging display circuit and current charging circuit respectively, be connected with voltage detecting circuit and current detection circuit on the described current charging circuit, the output of described voltage detecting circuit connects charging display circuit and feedback control circuit respectively, the output of described current detection circuit also connects described feedback control circuit, and the output of described feedback control circuit passes through control circuit for pulse-width modulation, power driving circuit is connected with described high frequency voltage descending transformer.
Between described voltage detecting circuit and described feedback control circuit, also can connect timing circuit.
The utility model uses in the time of can be with the various lead-acid batteries of existing 12V, 24V, 36V, 48V, 60V, 64V, 72V and 80V and lithium cell charging, can be made into no demonstration backlight and two kinds of series of demonstration backlight are arranged.
Characteristics:
One, adopt liquid crystal display to indicate whole charging process, it is clear, accurate that the Chinese demonstration adds icon display, and the user can grasp the process of charging at any time, can know the power shortage degree of battery, grasps the length that needs the charging interval.
Two, increased multiple detection and protection:
1, to the accurate detection of cell voltage.By liquid crystal display battery progress bar cell voltage is fed back to the user accurately.
2, the battery connection status is accurately judged.By electric circuit inspection whether battery is connected and to make accurate judgement, in case do not connect, LCDs will show that the user of unloaded content announcement need reconnect.When in a single day occurring connecting situation about coming off simultaneously in charging process, circuit also will be made judgement, and the user of announcement need reconnect.
3, circuit has also increased the plesichronous defencive function.In case enter charged state, total charging interval can enter the safe charging voltage status after reaching set point automatically, guarantees that battery is not filled drum.Simultaneously monitoring voltage reaches when making second timing ga(u)ge after the set point, enters the safe charging voltage status automatically behind timing time, guarantees that each economize on electricity of battery pack presses that the protection battery is not overcharged when uneven.
Description of drawings
Fig. 1 is a kind of circuit theory diagrams of the present utility model.
Embodiment
As shown in Figure 1, the liquid crystal display charger of electric motor car is provided with a rectifier filter that can be connected with mains supply, the other end at this rectifier filter connects the high frequency voltage descending transformer, the output of high frequency voltage descending transformer connects another rectifier filter, and the output of this rectifier filter connects charging display circuit and current charging circuit respectively.Be connected with voltage detecting circuit and current detection circuit on the current charging circuit, the output of voltage detecting circuit connects charging display circuit and feedback control circuit respectively, the output of current detection circuit also connects feedback control circuit, and the output of feedback control circuit is connected with the high frequency voltage descending transformer by control circuit for pulse-width modulation, power driving circuit.Between voltage detecting circuit and feedback control circuit, also can connect timing circuit.
