Abstract
The invention relates to an electric vehicle accessory, in particular to a charger for an electric vehicle. The charger comprises a controller and a charging circuit, wherein the charging circuit is connected with the controller; a Hall current sensor is arranged in the charging circuit and connected with the input end of the controller; and the output end of the controller is connected with a display. By using the structure, whether a rechargeable battery is fully charged or not is correlated with charging current, so that whether the battery is fully charged or not can be known by detecting a current value in the charging process by using the Hall current sensor in a charger detection device, a green lamp is lightened when the battery is fully charged, and a red lamp is lightened when the battery is not fully charged.
Description
Technical field
The present invention relates to the charger of a kind of electric accessory motor, particularly a kind of electric motor car.
Background technology
Battery of electric vehicle is the core component of electric motor car, before electric motor car uses, need charge to battery of electric vehicle.Whether during charging, whether need know charges finishes, need charge with accomplishing to battery of electric vehicle and detect.
Summary of the invention
The technical issues that need to address of the present invention provide and a kind ofly can detect the checkout gear whether electric car charger is full of.
For solving above-mentioned technical problem; Electric car charger checkout gear of the present invention comprises controller and charging circuit; Said charging circuit is connected with controller, is provided with Hall current sensor in the said charging circuit, and said Hall current sensor is connected with the input of controller; The output of said controller is connected with display.
Said display is red LED and the green LED that is arranged on the charger; Said red LED, green LED are connected with the output of controller respectively.
After adopting said structure; Because whether rechargeable battery is full of and charging current between exist and get in touch; Current value when Hall current sensor in the charger checkout gear detects charging just can know whether battery is full of, if be full of then be shown as green light, is not full of and then is shown as red light.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation.
Fig. 1 is a structural representation of the present invention.
Among the figure: 1 is the charger checkout gear, and 2 is charging circuit, and 3 is controller, and 4 is Hall current sensor, and 5 is red LED, and 6 is green LED
Embodiment
Electric car charger checkout gear 1 as shown in Figure 1 comprises controller 3 and charging circuit 2, and said charging circuit 2 comprises live part and plug.Charging circuit 2 is connected attaching plug through plug with battery of electric vehicle, so just can charge to battery of electric vehicle.Said charging circuit 2 is connected with controller 3, is provided with Hall current sensor 4 in the promptly said charging circuit 2, and said Hall current sensor 4 is connected with the input of controller 3; The output of said controller 3 is connected with display.Because when battery of electric vehicle is charged, the difference of battery of electric vehicle electric weight, the size of charging current is also different, can judge whether battery of electric vehicle is full of through the appearance not of uniform size of charging current in the detection charging circuit 2.Hall current sensor 4 in the charging circuit 2 is transferred to controller 3 with charging current value in the circuit, and 3 pairs of different current values of controller are made corresponding judgment.Said display is red LED and the green LED that is arranged on the charger; Said red LED, green LED are connected with the output of controller 3 respectively.
When controller 3 was judged the battery of electric vehicle underfill according to charging current value, control output signal made red LED work, and when judging battery of electric vehicle and be full of, control output signal makes green LED work.Certainly, display of the present invention also can adopt other to show the device whether battery of electric vehicle is full of, and such conversion all drops within the scope of the present invention's protection.
Claims (2)
1. electric car charger checkout gear; Comprise controller and charging circuit; Said charging circuit is connected with controller, it is characterized in that: be provided with Hall current sensor in the said charging circuit, said Hall current sensor is connected with the input of controller; The output of said controller is connected with display.
2. according to the described electric car charger checkout gear of claim 1, it is characterized in that: said display is red LED and the green LED that is arranged on the charger; Said red LED, green LED are connected with the output of controller respectively.
