Detailed Description
Example 1
As shown in fig. 1, a vehicle-mounted auxiliary battery charge controller, the technical scheme of adoption is, including auto-change over device 1, auto-change over device 1 includes voltage detection module 101, relay 102, voltage detection module 101's input electric connection ACC electric door 4, voltage detection module 101's output inserts relay 102's input circuit, relay 102's output circuit one end electric connection generator 3, other end electric connection auxiliary battery 5, electric connection has main battery 2 on the generator 3 output, auxiliary battery 5 and the 6 electric connection of living area consumer.
The voltage detection module 101 detects that the voltage signal value is less than 48V and the detection precision is 0.01V.
The relay 102 is a voltage relay.
The utility model discloses a theory of operation: when the ACC switch 4 is in a closed state, the voltage detection module 101 does not detect voltage, so that the relay 102 is in an off state, at this time, the main battery 2 and the auxiliary battery 5 are disconnected, and the generator 3 cannot charge the auxiliary battery 5; when the vehicle is ignited, the voltage of the ACC switch 4 is 0, the voltage detection module 101 does not detect the voltage, the relay 102 is in an off state, the main battery 2 and the auxiliary battery 5 are disconnected, and the generator 3 cannot charge the auxiliary battery 5; the post ignition voltage detection module 101 detects the voltage of the ACC switch 4, and turns off the relay when the voltage is lower than a design value
102, when the main battery 2 and the sub-battery 5 are disconnected and the generator 3 cannot charge the sub-battery 5, and when the voltage is higher than a design value, the relay 102 is turned on to connect the main battery 2 and the sub-battery 5 and the generator 3 starts charging the sub-battery 5.
Components and circuit connections not described in detail herein are prior art.
Although the present invention has been described in detail with reference to the specific embodiments, the present invention is not limited to the above embodiments, and various changes can be made without departing from the spirit of the present invention within the knowledge range of those skilled in the art, and modifications or variations without creative efforts are still within the scope of the present invention.
