Record module by signal receiving terminal is connected on motor switch one and battery connecting line, when battery electric quantity finishes, by electronic
The connection of the cut-out charging current of switch one and battery, farthest protect battery, while passage time logging modle records
The time required to charging is true every time, the next reasonable arrangement charging interval has been easy to, while electricity is set on battery electric power output line
Dynamic switch two and the motor switch three to short-circuit the battery, when charging finishes, if charger continues to be connected on power supply
Wait, power is provided to the standby components on automobile using charger, it is powerful so as to keep battery electric power not to be lost, it is applicable
Wide scope, greatly improve the service life of battery.
To solve the above problems, the technical solution used in the present invention is as follows:
A kind of electric charging controller for electric motor vehicle, including MCU control unit, charging circuit, battery, electric power detection module, time record
Module, electricity quantity display module, charging interval display module and motor switch one, described charging circuit include charging successively
Mouth, rectifier filter one, transformer, rectifier filter two, described MCU control unit are connected with transformer, control its work,
Described rectifier filter is connected with battery, gives its charging, and described battery is provided with power input lines, described electric power detection
Module by signal receiving terminal is connected with battery, signal output part is connected by MCU control unit with electricity quantity display module, and described is whole
Motor switch one is provided between stream wave filter two and battery, described time recording module signal receiving end is connected to motor switch
One with battery connecting line, signal output part be connected by MCU control unit with charging interval display module, described driven opening
One is closed to be connected with MCU control unit, be controlled by opening or closing.
Further, in addition to motor switch two and motor switch three, described motor switch two are arranged on power input lines
On, described one end of motor switch three is connected on motor switch two and the connecting line of rectifier filter two, the other end is connected to electricity
