Abstract

The invention discloses a static loss control system of vehicle-mounted charging controller, which comprises a charging controller, wherein the charging controller includes a switch unit, a control unit and a pulse trigger unit, the pulse trigger unit is separately electrically connected with a vehicle-mounted power source and the switch unit, the pulse trigger unit is used for inducting pulse signal sent from a power supply unit to control the conduction of the switch unit, and the switch unit controls the on-off of a circuit between the control unit and the vehicle-mounted power source. The static loss control system of vehicle-mounted charging controller of the invention is provided with the pulse trigger unit, which is used for inducting pulse signal sent from a power supply device to control the conduction of the switch unit, thereby realizing the monitoring of connection state of the power supply device and a battery pack to be charged. Only when the power supply device is being connected will the pulse trigger unit respond and control the conduction of the switch unit, thereby reducing the static loss of the vehicle-mounted power source (vehicle-mounted storage battery) effectively.

Description

technical field [0001] The invention relates to a static loss control system of a vehicle-mounted charging controller. Background technique [0002] With the promulgation of the latest regulations and standards of the American Standard, the European Standard and the National Standard on the conduction on-board charger, a charging controller needs to be installed inside the electric vehicle to confirm the status with the power supply equipment, so the charging controller on the electric vehicle needs to be constantly monitored. Whether it is connected with the power supply equipment, and the charging controller is electrically connected with the vehicle battery and powered by the battery. Therefore, the charge controller will continuously consume the power of the on-board battery (the power supply for the low-voltage system). [0003] This loss is static loss, that is, the loss when the power source, such as a battery, is not charged. If the static loss is too large, it may...
