Description

An electric vehicle timing charger

technical field

The utility model relates to a timing charger for an electric vehicle.

Background technique

There are more and more electric vehicles in China now, and people usually use chargers to charge the batteries of electric vehicles. Many chargers have a charging protection function, that is, the charger controls the switch of the charger by detecting the voltage value of the battery of the electric vehicle, but the quality of the products of many charger manufacturers is uneven, and it often occurs that the charging time is too long and the battery of the electric vehicle is damaged situation occurs. Because the charging time is too long and the circuit cannot be cut off in time, on the one hand, the service life of the charger is reduced, and on the other hand, the battery of the electric vehicle is overcharged and damaged.

Utility model content

The purpose of the utility model is to provide a timing charger for an electric vehicle which uses a timer to charge and controls the charger to be turned on and off in view of the deficiencies in the prior art.

For realizing the above object, the utility model adopts the following technical solutions:

A timing charger for an electric vehicle, comprising an electric vehicle charging circuit and a storage battery, characterized in that: the timing charger for an electric vehicle also includes: a timing module for setting charging time, for performing on-off control according to timing signals A control device, the output end of the timing module is connected to the input end of the control device.

It is further characterized in that: the timing module includes a timing setting button and a timer, and the output end of the timing setting button is connected to the input end of the timer.

It is further characterized in that: the control device is a relay, the input end of the relay is connected to the output end of the timer, and the output end of the relay is connected to the electric vehicle charging circuit.

It is further characterized in that: the electric vehicle timing charger also includes a power supply for power supply and a switch, the input end of the switch is connected to the power supply, and the output end of the switch is connected to the input end of the timer.

Compared with the prior art, the electric vehicle timing charger of the utility model uses a timer to control the charging time of the charging circuit, which can improve the life of the charging circuit and prevent the battery of the electric vehicle from being damaged due to overcharging; the circuit structure of the electric vehicle timing charger is simple, High reliability; due to the use of a timer, the timing can be adjusted at will according to requirements, and it is easy to use.

Description of drawings

Fig. 1 is a structural schematic diagram of the utility model;

Among them: 1. 220V power supply; 2. Switch; 3. Timing setting button; 4. Timer; 5. Relay; 6. Charging circuit; 7. Electric vehicle battery.

Detailed ways

A timing charger for an electric vehicle as shown in Figure 1, the timing charger for an electric vehicle is composed of a 220V power supply 1, a switch 2, a timing charging button 3, a timer 4, a relay 5, a charging circuit 6, and an electric vehicle storage battery 7 .

The charging circuit 6 has a charging protection function, and the trickle charging stage will be started after the charging is completed. The function of the timer 4 is mainly to prevent the charging circuit 6 from being energized for a long time under the premise of ensuring sufficient charging. On the one hand, it wastes electric energy and reduces the life of the charging circuit, and on the other hand, it prevents the electric vehicle battery 7 from being damaged by overcharging.

The user turns on the switch 2, and the 220V power supply 1 supplies power to the timer 4. The user sets the charging time of the battery 7 of the electric vehicle through the timing setting button 3 as required. After the timer 4 reaches the charging time set to start, the timer 4 connects the power supply of the relay 5, the normally open contact of the relay 5 is closed, and provides power to the charging circuit 6, and the charging circuit 6 begins to charge the battery 7 of the electric vehicle; After the timer 4 reaches the set end charging time, the timer 4 disconnects the power supply of the relay 5, the normally open contact of the relay 5 is disconnected, and stops supplying power to the charging circuit 6, and the charging circuit 6 stops charging the battery 7 of the electric vehicle. The purpose of regularly charging the battery 7 of the electric vehicle is realized.

The user can adjust the charging setting time of the timer 4 through the timing setting button 3 according to the usage of the actual electric vehicle storage battery 7, and change the charging time.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
