Electric vehicle charging connector, connector assembly and electric vehicle charging system
First Claim
1. An electric vehicle charging connector assembly for use in charging a power battery provided in a body of an electric vehicle with an external power source, the connector assembly comprising:
- a) a vehicle side connector housing provided on the body of the electric vehicle;
b) vehicle side electrodes disposed in the vehicle side connector housing and electrically connected to the power battery;
c) a grip handle having a cavity therein and being capable of being gripped by an operator, the grip handle comprising an upper half portion, a lower half portion and an end;
d) an external connector housing provided on the end of the grip handle and configured to mate with the vehicle side connector housing;
e) external electrodes disposed in the external connector housing, said external electrodes being electrically connected to the vehicle side electrodes when the external connector housing is mated with the vehicle side connector housing;
f) a charging information display circuit operatively connected to the power battery while said external electrodes are connected to said vehicle side electrodes;
g) a power cable connected to the external electrodes, the power cable extending through the cavity of the grip handle from the external electrodes and down and out of the lower half portion of the grip handle; and
h) a display disposed on the upper half portion of the grip handle, said display being operatively connected to said display circuit so as to display information generated by the display circuit when said external connector housing is mated with the vehicle side connector housing.

Abstract
An electric vehicle charging connector used for charging a power battery of an electric vehicle includes connector holder and a display section mounted in an upper portion of the connector holder. The display section includes red and green light-emitting diodes and a seven-segment two-digit numeric display including light-emitting diodes. The red light-emitting diode is turned on while the power battery is being charged. The green light-emitting diode is turned on instead of the red light-emitting diode when charging has been completed. Either the time elapsed after the charging operation has been initiated or the remaining capacity of the power battery is displayed by the numeric display.
