Example two
According to the embodiment of the invention, the charging in two modes of fast charging and slow charging can be realized through one socket of the vehicle body. Specifically, the socket of the vehicle body is an existing alternating current charging socket (namely a slow charging socket), and the slow charging socket can be originally inserted by a charging gun of an alternating current charging pile to realize slow charging.
The embodiment of the invention provides a new energy automobile direct current-to-alternating current charging adapter, which comprises: an ac charging receptacle, a first relay, a second relay, a battery management system, and the ac-dc gun head conversion head of embodiment one.
One end of the reserved interface L2 in the alternating current charging socket and one end of the reserved interface L3 in the alternating current charging socket are both connected with the battery management system.
One end of a charging wire L1 in the alternating current charging socket is connected with the positive electrode of the battery pack through a first relay, and one end of a charging wire N in the alternating current charging socket is connected with the negative electrode of the battery pack through a second relay; the control end of the first relay and the control end of the second relay are connected with the battery management system.
When the direct current charging pile is used for charging the new energy automobile, the other end of the communication bus S+ in the automobile body socket end of the alternating current-direct current gun head conversion head is connected with the other end of the reserved interface L2, the other end of the communication bus S-is connected with the other end of the reserved interface L3, the other end of the direct current voltage transmission line DC+ is connected with the other end of the charging line L1 in the alternating current charging socket, and the other end of the direct current voltage transmission line DC-is connected with the other end of the charging line N in the alternating current charging socket; after receiving the direct current charging signals transmitted by the reserved interface L2 and the reserved interface L3, the battery management system controls the first relay and the second relay to be attracted, so that the direct current charging pile charges a battery pack.
Referring to fig. 1, one end of a signal line CP in an ac charging receptacle is connected to an on-vehicle charger. When the direct current charging pile is used for charging the new energy automobile, the other end of the signal line CC1 in the automobile body socket end of the alternating current-direct current gun head conversion head is connected with the other end of the signal line CP in the alternating current charging socket, and the vehicle-mounted charger is used for prompting and identifying a charging gun of the direct current charging pile.
One end of a body ground wire in the alternating-current charging socket is grounded. When the direct current charging pile is used for charging the new energy automobile, the other end of the automobile body grounding wire in the alternating current charging socket is connected with the other end of the equipment grounding wire in the automobile body socket end of the alternating current-direct current gun head conversion head.
In order to realize quick charging of the new energy automobile by sharing the alternating current charging socket with the direct current-to-alternating current charging adapter, the problem of long charging time is solved, one end of a charging wire L1 in the alternating current charging socket is also connected with an on-board charger through a third relay, and one end of the charging wire N in the alternating current charging socket is also connected with the on-board charger through a fourth relay; the control end of the third relay and the control end of the fourth relay are connected with the battery management system. When the direct-current charging pile is used for charging the new energy automobile, the battery management system controls the third relay and the fourth relay to be disconnected.
L2 and L3 on the ac charging outlet are reserved interfaces (i.e. empty interfaces) and only when three-phase power is developed, L2 and L3 are used, but only 220V is currently used, and three-phase power is not yet developed, so L2 and L3 are reserved all the time. In this solution, in order to develop direct current charging (380V high voltage charging), L2 is changed to S '+, L3 is changed to S' -, and S '+ and S' -are both signal lines (not charging lines), the battery management system directly activates the first relay and the second relay in the battery pack, and after activating the first relay and the second relay, the direct current of the direct current charging pile is directly connected to the battery pack through the alternating current charging socket of the vehicle body, so as to directly charge the battery pack, so that the vehicle-mounted charger (OBC) is not required, so that the embodiment of the invention is developed through the alternating current charging socket instead of the direct current charging socket. In fig. 1, the ac charging receptacle constitutes an ac charging port, and the first relay, the second relay, the third relay, and the fourth relay are all disposed in the dc charging distribution box. The direct current charging path is: the method comprises the steps of DC+ of an alternating current/direct current gun head conversion head, L1 of an alternating current charging port, a first relay, a battery pack, and N of the direct current/alternating current gun head conversion head, a second relay and the battery pack.
Low voltage signal conversion: the signal line S '+, the signal line S' -are communicated with the battery management system during direct current charging, and the signal line CC1 is used for detecting the vehicle-mounted charger through the signal line CP, so that the vehicle-mounted charger prompts and identifies the charging gun of the direct current charging pile after detecting the charging gun of the direct current charging pile.
High voltage power supply conversion: when the vehicle-mounted battery pack is charged, the third relay and the fourth relay are controlled to be closed, and the alternating current is converted by the vehicle-mounted charger and then enters the battery pack. When the direct current is charged, the direct current positive relay and the direct current negative relay are controlled to be attracted, and the direct current directly enters the battery pack through the relay. Specifically, the signal line CC1 and the signal line CC2 are used for detecting whether a charging gun is identified, when the charging gun of the direct current charging pile is inserted, the signal line CC1 and the signal line CC2 are started, the third relay and the fourth relay are disconnected, the alternating current is powered off, and the direct current is powered on, namely the signal line CC1 and the signal line CC2 are equivalent to a switch.
New energy automobile direct current-to-alternating current charging adapter: the quick and slow charging function is achieved by only adding an alternating current-direct current gun head conversion head when quick charging is adopted, and the portable vehicle is convenient.
According to the invention, the direct-current quick charging is carried out through the alternating-current charging socket of the new energy automobile, so that the charging time is shortened, and the direct-current quick charging cable assembly can be canceled, thereby meeting the requirement of reducing the cost.
After the new energy vehicle type cancels the fast charging socket proposal, the difference of the fast charging socket proposal is not large in use experience, but the cost of a bicycle is reduced, and the new energy vehicle type is recommended to be used in a small electric quantity vehicle type (below 32 kWh).
In the present specification, each embodiment is described in a progressive manner, and each embodiment is mainly described in a different point from other embodiments, and identical and similar parts between the embodiments are all enough to refer to each other.
The principles and embodiments of the present invention have been described herein with reference to specific examples, the description of which is intended only to assist in understanding the methods of the present invention and the core ideas thereof; also, it is within the scope of the present invention to be modified by those of ordinary skill in the art in light of the present teachings.
