Detailed description of the invention
As mentioned in the beginning, the literature is devoted to for charging cable provides actv. (particularly cost-effective) and antitheft efficiently.Like this antitheft therefore particularly important, because charging cable typically has intrinsic value.
Fig. 1 shows the block scheme of the exemplary charge system with charging cable 100 and vehicle 150.Vehicle 150 comprises electric energy accumulator (not shown), and this electric energy accumulator can fill from power supply grid (not shown) with electric energy.Vehicle 150 comprises charging socket 160, can the plug 110 of corresponding vehicle side of grafting charging cable 100 on this charging socket.
The plug 110 of the vehicle side of charging cable 100 is connected with cable control unit 120 by the first cable.The cable control unit 120 of charging cable 100 can be set up to for being communicated with the charging control unit 151 of vehicle 150, to control process of charging by one or more control line of the first cable.Communication can realize according to control signal (such as according to standard ISO/IEC 62196).
Charging cable 100 also comprises the second cable, and this second cable is set up to for being connected with power supply grid by the plug 130 of the cable control unit 120 of charging cable 100 by the grid side of charging cable 100.The plug 130 of grid side such as can comprise safety plug, the plug of F type and/or the plug of E+F type.Power supply grid can provide alternating current (such as at the power supply voltage of 230V and the frequency of 50Hz time or at the power supply voltage of 110V and the frequency of 60Hz time).
Therefore charging cable 100 can be set up to for by the plug 130 of grid side and by (namely second) cable reception single-phase alternating current of grid side.But be also possible and not shown for the embodiment of two-phase and three phase current transmission.In addition, the electric energy obtained from power supply grid can also be transferred to vehicle 150 by the plug 110 of (that is first) cable of vehicle side and vehicle side.Process of charging and particularly provide electric energy can be controlled by the cable control unit 120 of charging cable 100 to vehicle 150.In order to for controlling the communication objective of process of charging, the cable (being different from the cable of grid side) of vehicle side typically comprises dedicated signal lines or control line.Special control line can extend on the control contact element 113 (also referred to as pin) of the plug 110 of vehicle side and on the corresponding control contact element 163 of charging socket 160.
The plug 110 of vehicle side also comprises multiple physical contact 111 except at least one controls contact element 113, and these physical contact can enter induction type to the corresponding contact element 161 of charging socket 160 and connect.Physical contact 111 typically comprises live wire contact element (for first-phase), zero line contact element and ground contact.Be possible for the other contact element of mutually 2 and 3 (L2 and L3) as embodiment, but do not depict.The physical contact 111 of the plug 110 of vehicle side is by the corresponding power lead of the first and second cables and connected to the corresponding physical contact 131 of the plug 130 of grid side by the cable control unit 120 of charging cable 100.Charging current can be transferred to vehicle 150 from power supply grid by power lead.
At this, one or more power lead can be interrupted by the contactless switch 123 in cable control unit 120.Particularly live wire and zero line can be interrupted, to forbid the charging current of the plug 110 from the plug 130 of grid side to vehicle side by the corresponding contactless switch 123 in cable control unit 120.Described one or more contactless switch 123 can drive control by the control module 121 of cable control unit 120.
The plug 110 of vehicle side can comprise close to contact element 112 (also referred to as close to pin) in addition, and this can enter connection to the corresponding of charging socket 160 close to contact element 162 close to contact element.Typically, other contact elements 111,113 (be particularly shorter than physical contact 111 and/or be shorter than and control contact element 113) that can be shorter than the plug 110 of vehicle side close to contact element 112 of the plug 110 of vehicle side.Additionally or alternatively, other contact elements 161,163 (be particularly shorter than physical contact 161 and/or control contact element 163) that can be shorter than charging socket 160 close to contact element 162 of charging socket 160.By setting up close to line between charging socket 160 (or charging control unit 151 of vehicle 150) and the cable control unit 120 of charging cable 100 close to contact element 112,162.Based on close to the fact one of being at least shorter than other contact elements of plug 110 and/or charging socket 160 in contact element 112,162, can guarantee: if there is continuous print close to line, then the plug 110 of vehicle side is sufficiently inserted in charging socket 160, thus the user that can get rid of charging cable on the one hand by mistake contacts power lead and moreover ensure that the safe socket of HV pin (that is physical contact) connects to avoid (such as component) damage.
Charging cable 100 can be guaranteed to avoid extracting of non-automated by the lock pin 164 (such as by plastics lock pin) in the charging socket 160 of vehicle side.Lock pin 164 can be provided with corresponding space on plug 110 or corresponding plate 114, to guarantee the locking between charging socket 160 and the plug 110 of vehicle side.Lock pin 164 such as can be similar to fuel lid closing appliance and be moved into when vehicle 150 locks like that in the space 114 of charging cable plug 110.In other words, by the locking of vehicle 150, such as can cause by middle control closing appliance the connection be latched between plug 110 and charging socket 160.
The extracting of plug 110 of vehicle side can by identifying close to contact element 112.As mentioned above, typically there is different length, the charging plug 110 only pushing half can be detected close to contact element 112 and control contact element 113.Based on the length that these are different, extract close to contact element 112 within the relatively short time when extracting the plug 110 of vehicle side, and control contact element 113 and be still in the corresponding contact element 163 of charging socket 160 and contact.But this state of having interrupted also not interrupting close to line control line such as can be detected by the control unit 151 of vehicle 150 and/or cable control unit 120.
Typically, lock pin 164 so designs, and makes this lock pin 164 fracture from predetermined load limit, not damage the vehicle body of vehicle 150 under improper load condition.In other words, lock pin 164 typically so designs, and make before vehicle 150 is damaged, lock pin 164 disconnects.This can realize getting loose under the blocking of vehicle 150 when not having large power consumption charging cable 100.In grid side, charging cable 100 is not typically insured completely.Therefore, charging cable 100 can relatively simply complete function be stolen well and be disposed of stolen goods.
