Description of drawings
Fig. 1 is electrical block diagram of the present utility model.
The specific embodiment
As shown in Figure 1, a kind of series hybrid-power overall height pressing system power-on and power-off control circuit, comprise high-tension battery module 1, be connected in parallel on high-tension battery module 1 two ends driver module 2, be connected in parallel on the electricity generation module 3 at driver module 2 two ends; Between the positive pole of driver module 2 and high-tension battery module 1, be connected to main contactor S2 parallel with one another and precharge contactless switch S3, wherein, precharge contactless switch S3 is serially connected with pre-charge resistance R, the withstand voltage of pre-charge resistance R is 1.5 times of cell pressure, anti-flow valuve is that 1.5 times of cell pressures are divided by the pre-charge resistance value, the contact point withstand voltage of main contactor S2 is cell pressure more than 1.5 times, and the adhesive line is wrapped electric induction voltage less than 1.5 times of low voltage voltage; Electricity generation module 3 is connected in parallel on high-tension battery module 1 two ends, is connected to controllable relays S1 between its positive pole, and the adhesive withstand voltage of controllable relays S1 is higher than 1.5 times of cell pressures, and the line at controllable relays S1 two ends is greater than 25 square millimeter lines footpath.
Principle of work of the present utility model:
When driver module 2 receives that car load powers on instruction, driving governor control precharge contactless switch S3 closure, high-tension battery module 1 begins the charging of the electric capacity of high pressure consumer (not shown in figure 1)s such as electrical motor, makes voltage between the high pressure consumer positive and negative busbar near the voltage at high-tension battery module 1 two ends; After precharge was finished, driving governor control main contactor S2 closure was controlled precharge contactless switch S3 simultaneously and is disconnected; Electricity generating controller detect main contactor S2 power on finish after, control controllable relays S1 closure is finished car load high-pressure system power up.
When driver module 2 receives under the car load that electricity instruction or car load low-voltage power supply are cut off, because logic control element all can only be used low-voltage power supply on the car, so driving governor can enter power-down state, also can disconnect immediately by the main contactor S2 of its control, thereby disconnected being connected between high pressure consumer and the high-tension battery module 1; Because electricity generating controller connects normal electricity, so this moment, electricity generating controller can not enter power-down state, also can not disconnect by the controllable relays S1 of its control; Electricity generation module 3 electricity that (about 200ms) sends in following electricity time-delay can charge to high-tension battery module 1 by the loop of it and high-tension battery module 1 and controllable relays S1 formation; When electricity generating controller detects electrical generator and stops to generate electricity fully, control controllable relays S1 disconnects, and (what is called is suicide down to open suicide electricity down, refer to when detect oneself can below when electricity, source switch disconnection by ACTIVE CONTROL oneself realizes down), finish electric process under the car load high-pressure system.
The above embodiment only is that preferred implementation of the present utility model is described; be not that scope of the present utility model is limited; under the prerequisite that does not break away from the utility model design spirit; various distortion and improvement that those of ordinary skills make the technical solution of the utility model all should fall in the definite protection domain of claims of the present utility model.
