Description
Technical field
The utility model provides a kind of vehicle-mounted dual power supply device, belongs to the configuration of DC24V vehicle electric and installs vehicular high-power power consumption equipment power supply technique field additional.
Background technology
Equipped starting type accumulators in current conventional truck, large but the continuous discharge ability of explosive force, under engine not start operating performance, discharged or defective battery fault can be caused after long-time use vehicular high-power power consumption equipment, the lighter causes voltage fluctuation to affect power consumption equipment normally to work use, cause vehicle to start time serious.Start battery tension instantaneously after storage battery power shortage can drag down, once lower than load equipment operating voltage, equipment will be caused to restart, obliterated data.For this problem, traditional solution is for installing power module of voltage regulation additional, and cost is higher.
Summary of the invention
The purpose of this utility model provides a kind of based on the vehicle-mounted dual power supply device of one-way commutation bridge just for weak point existing in above-mentioned prior art, this device can realize vehicle starting system and vehicular high-power electricity consumption load dual-power is powered, namely realize load and start the object of powering separately separately and charging simultaneously, be applicable to conventional truck and install high power vehicular power consumption equipment vehicle additional.
The purpose of this utility model realizes by following technique measures:
Of the present utility modelly charge relay and one-way commutation bridge is utilized to build starting storage battery and load storage battery double power supply circuit based on the vehicle-mounted dual power supply device of one-way commutation bridge, realize starting storage battery and load storage battery is mutually isolated, reach that vehicular high-power electric loading is powered separately, the object of automatic charging simultaneously; Wherein: for starter motor provides the starting storage battery input of power supply and one-way commutation bridge input to be electrically connected with the power output end of generator respectively, described charge relay is connected between starting storage battery and one-way commutation bridge; One end of described load storage battery is connected with one-way commutation bridge, the other end is connected with vehicular high-power electric loading.
The utility model, after startup vehicle, holds closed realization of control charge relay to power to vehicle-mounted electric installation and the charging of two group storage batteries by generator D+.
The beneficial effects of the utility model are as follows:
When design of the present utility model installs large power-consuming equipment additional based on conventional truck, should ensure that power consumption equipment extends working time as far as possible under the prerequisite not starting vehicle, not affecting again vehicle normally starts needs simultaneously.Because the utility model is by increase by tunnel load battery feed and one-way commutation Biodge device circuit, make former car storage battery and load storage battery mutually isolated, independently-powered separately.Be independent of each other before engine start, output 28V voltage is held automatically to control charge relay break-make by generator D+ after engine start, and then realize charge circuit and automatically connect, supply car load electrical load and load device storage battery automatic charging by electric generator of vehicle.

Embodiment
The utility model is further described below with reference to embodiment (accompanying drawing):
As shown in Figure 1, 2, of the present utility modelly charge relay 3 and one-way commutation bridge 4 is utilized to build starting storage battery 1 and load storage battery 7 double power supply circuit based on the vehicle-mounted dual power supply device of one-way commutation bridge, realize starting storage battery and load storage battery is mutually isolated, reach that vehicular high-power electric loading is powered separately, the object of automatic charging simultaneously; Wherein: for starter motor provides starting storage battery 1 input of power supply and one-way commutation bridge 4 input to be electrically connected with the power output end of generator 2 respectively, described charge relay 3 is connected between starting storage battery 1 and one-way commutation bridge 4; One end of described load storage battery 7 is connected with one-way commutation bridge 4, the other end is connected with vehicular high-power electric loading 8.
The utility model, after startup vehicle, holds closed realization of control charge relay to power to vehicle-mounted electric installation and the charging of two group storage batteries by generator D+.
Operation principle of the present utility model is as follows:
1, make load power source relay 6 adhesive by mains switch 5, connect load storage battery 7 and power for vehicular high-power electric loading 8.
2, when not ato unit, vehicular high-power electric loading 8 working load storage battery 7 power supply ensures normal use.
3, after the engine started, after engine 2 generates electricity, D+ end output signal controls charge relay 3 and works, and after charge relay 3 adhesive, generator powered end B+ holds and charges by one-way commutation bridge 4 is unidirectional to load storage battery 7 and be that vehicular high-power electric loading 8 is powered simultaneously.
