The invention discloses a battery charging system of a hybrid electric tractor, belonging to a battery charging system. A battery charging system with reasonable coexistence of multiple charging sources is provided. The battery charging system comprises a generator set, a low-voltage battery, a high-voltage battery, a DC (direct current) converter and a controller, wherein the generator set (1) is respectively connected with the low-voltage battery (2), a voltage signal detector (6) and a voltage output controller (8); the high-voltage battery (3) is connected with the low-voltage battery (2) by the DC converter (4); the voltage signal detector (6), the controller (7), the voltage output controller (8) and the high-voltage battery (3) are connected in sequence; an AC (alternating current) charger (5) is respectively connected with the voltage signal detector (6) and a voltage output controller (8); and the high-voltage battery (3) is connected with the controller (7). The battery charging system can overcome the defect that the low-voltage battery can not be compensated because a generator can not work for a long time.
Description
Technical field: the present invention relates to a kind of battery charging system, relate in particular to a kind of hybrid power tractor battery charging system.
Background technology: at present, the hybrid power tractor only adopts a charge power supply that electric energy is provided mostly; Because the hybrid power tractor belongs to heavy engineering machinery, energy consumption is higher, and is therefore relatively strict to the requirement of operating environment.If can adopt two charge power supplies that electric energy is provided, then can improve the adaptability of hybrid power tractor to operational environment.In addition, reasonably the charge in batteries management control system can realize energy-conservation, the prolongation life of storage battery effectively.
Summary of the invention: at the above-mentioned defective that exists in the prior art, the present invention aims to provide a kind of a plurality of chargings source hybrid power tractor battery charging system of coexistence rationally.
To achieve these goals, the present invention by the following technical solutions: it comprises generating set, low tension battery, high tension battery, direct current transducer and controller; Generating set is connected with low tension battery, voltage signal detector, voltage o controller respectively, high tension battery is connected with low tension battery by direct current transducer, voltage signal detector, controller, voltage o controller and high tension battery connect successively, commercial power charged machine is connected with voltage signal detector, voltage o controller respectively, and high tension battery is connected with controller.
Compared with the prior art, the present invention is owing to adopted technique scheme, increased commercial power charged power supply, changed an original charge power supply into two charge power supplies and deposited, therefore avoided engine not cause low tension battery not have additional defective, prolonged the useful life of storage battery because of not working for a long time.
Description of drawings:
Fig. 1 is a structural representation of the present invention.
Among the figure: generating set 1 low tension battery 2 high tension batteries 3 direct current transducers 4 commercial power charged machine 5 voltage signal detectors 6 controllers 7 voltage o controllers 8
Embodiment: the invention will be further described below in conjunction with accompanying drawing and specific embodiment:
As shown in Figure 1: generating set 1 is connected with low tension battery 2, voltage signal detector 6, voltage o controller 8 respectively, high tension battery 3 is connected with low tension battery 2 by direct current transducer 4, voltage signal detector 6, controller 7, voltage o controller 8 and high tension battery 3 connect successively, commercial power charged machine 5 is connected with voltage signal detector 6, voltage o controller 8 respectively, and high tension battery 3 is connected with controller 7.
Operation principle:
Low tension battery 2 is mainly that other low voltage equipment provides electric energy on ato unit and the car.Low tension battery 2 has two kinds of charging modes: a kind of mode is that the low voltage generator that engine drives generating set 1 directly charges to low tension battery 2, and another kind of mode is that high tension battery 3 carries out electric weight by 4 pairs of low tension batterys of direct current transducer 2 and keeps.During engine operation, the voltage of direct current transducer 4 is lower than generating set 1 voltage, and low tension battery 2 is charged by generating set 1; When engine was not worked, direct current transducer 4 voltages were a little more than low tension battery 1 voltage, and direct current transducer 4 can avoid low tension battery 2 to cause electric weight low excessively because of long-time no generating set 1 charging.
5 pairs of high tension batteries of commercial power charged machine 3 carry out between charge period, and controller 7 is ignored all walking operations, and control hybrid power tractor is in can not walking states.
Claims (1)
1. a hybrid power tractor battery charging system comprises generating set, low tension battery, high tension battery, direct current transducer and controller; It is characterized in that: generating set (1) is connected with low tension battery (2), voltage signal detector (6), voltage o controller (8) respectively, high tension battery (3) is connected with low tension battery (2) by direct current transducer (4), voltage signal detector (6), controller (7), voltage o controller (8) and high tension battery (3) connect successively, commercial power charged machine (5) is connected with voltage signal detector (6), voltage o controller (8) respectively, and high tension battery (3) is connected with controller (7).
