Preferably, the described model from processor is STM32F207.
The utility model adopts above technical scheme compared with prior art, there is following technique effect: a kind of charging electric vehicle supervising device of the present utility model, adopt dual processor output contactor to be controlled simultaneously, make charger charging process there is multiple assurance, and circuit structure is simple, reliability is high, hardware cost is low, control is simple.
Accompanying drawing explanation
Fig. 1 is the structural representation of a kind of charging electric vehicle supervising device of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is described in further detail.
As shown in Figure 1, a kind of charging electric vehicle supervising device, comprises primary processor, from processor, charger, output contactor, battery BMS, two input isolators, two output isolators, described primary processor, from processor, communicate by letter mutually, primary processor, from processor, all communicate by letter with described charger, primary processor, from processor, all communicate by letter with described battery BMS, charger connects battery BMS through output contactor, primary processor is connected respectively two output isolators with two outputs from processor, from two outputs of processor, connect respectively two output isolators, the output of two output isolators connects output contactor, the input of output contactor connects respectively two input isolators, the output of output contactor connects respectively two input isolators, two input isolators all with primary processor with from processor, be connected.Primary processor, between processor by CAN bus 1 communication; Primary processor, from processor, all communicate by letter by CAN bus 2 with charger; Primary processor, from processor, all communicate by letter by CAN bus 3 with battery BMS; The model of primary processor is LPC1778; From the model of processor, be STM32F207.
The workflow of charging electric vehicle supervising device: with primary processor with from these two processors of processor, control chargers, primary processor with from processor, by 1 maintenance of CAN bus, communicate by letter; Primary processor, from processor and charger, by CAN bus 2, keep communicating by letter; Primary processor, from processor and BMS, by CAN bus 3, keep communicating by letter; Primary processor and respectively have two outputs from processor, two output isolators of interconnection, at output isolator place, first will after each input negate, realize logical AND, this logical AND signal is used for controlling the output contactor of charger, realizes charger turning on and off battery output again; When four outputs of principal and subordinate processor are logic low simultaneously, the output of output isolator is effective, and output contactor is opened and can be charged the battery, otherwise output contactor closes, and do not charge the battery; The input signal of output contactor and its output state feed back to primary processor through input isolator and from processor, the isolation separately of input isolator Dui Mei road feedback, if it is inconsistent to feed back to the signal of the signal of arbitrary processor and the output of this processor, the inconsistent processor of signal cuts out output, when one of them processor cuts out, output isolator is not exported, and output contactor keeps closed condition; If two processors of principal and subordinate cut out output contactor, but output contactor status displays is still open mode simultaneously, primary processor directly makes output contactor coil blackout, closes output contactor.
Primary processor with from processor, by CAN bus 1, keep communicating by letter, every 5 milliseconds send 1 this oneself state to the other side, as overtime, do not receive partner state, thereby or partner state detected and extremely close output and disconnect output contactor, by CAN bus 2, send and cease and desist order to charger simultaneously, by CAN bus 3 and BMS system, complete charging flow complete charge.
At primary processor with when processor detects charger or BMS is abnormal or other are abnormal; if primary processor is working properly; by primary processor, by CAN bus 2, send and cease and desist order to charger, by CAN bus 3 and BMS system, complete charging flow complete charge.Otherwise by sending and cease and desist order to charger by CAN bus 2 from processor, by CAN bus 3 and BMS system, complete charging flow complete charge.
The utility model is controlled external cabling common port by relay switch, relay switch is normally closed, external cabling common port connects normally-closed contact, by block system relay normally-closed contact, directly cuts off and the link circuit of external cabling common port, thus cut-out output contactor current supply circuit.
Above embodiment is only explanation technological thought of the present utility model; can not limit protection range of the present utility model with this; every technological thought according to the utility model proposes, any change of doing on technical scheme basis, within all falling into the utility model protection range.
