Abstract
The utility model discloses a system for controlling start of an automobile engine. The system comprises a super capacitor energy storage component, a storage battery, a relay and a body control module, wherein the anode of the super capacitor energy storage component and the anode of the storage battery are respectively connected with the relay; the cathode of the super capacitor energy storage component is connected with the cathode of the storage battery; and the relay is also connected with the body control module. By the system, potential safety hazards which are caused by the reason that a capacitor filter is always connected with the storage battery are eliminated, and high current impact is buffered during the start of the engine.
Description
Technical field
The utility model relates to a kind of automobile engine starting control system.
Background technology
Present automobile engine starting control system is automotive battery and capacitor filter, and this capacitor filter is directly to be connected with storage battery, plays pressure stabilization function to a certain extent.Can not break off because capacitor filter one direct sum storage battery connects, have hidden danger on the safety.Along with the self-discharge of storage battery, the electric energy that stores in the electric capacity also reduces gradually.Mostly the structure of this capacitor filter is to use a plurality of 25V, the electric capacity parallel connection of 2200UF, and there are hysteresis in the storage and the speed of response of electric energy more.And the incision of electric capacity is uncontrolled, and the startup heavy current impact of driving engine is not played buffer action.
The utility model content
Utility model purpose: to the problem and shortage of above-mentioned prior art existence; The purpose of the utility model provides a kind of automobile engine starting control system; Solved capacitor filter and be connected the potential safety hazard of bringing always with storage battery, and the heavy current impact of driving engine when starting played buffer action.
Technical scheme: for realizing above-mentioned utility model purpose; The technical scheme that the utility model adopts is a kind of automobile engine starting control system; Comprise super capacitor energy-storage assembly, storage battery, relay and Body control module, the positive pole of said super capacitor energy-storage assembly is connected condenser respectively with the positive pole of storage battery, and the negative pole of said super capacitor energy-storage assembly connects the negative pole of storage battery; Said condenser also connects Body control module (BCM, body control module).
Said super capacitor energy-storage assembly preferably includes the super capacitor group of 2 groups of parallel connections, and every group of super capacitor group can comprise 6 series connected super capacitors.
Beneficial effect: 1. increased the handoff functionality of energy storage component, prolonged the service life of energy storage component, improved the startability of driving engine.Protected storage battery when starting, to receive the influence of heavy current impact; 2. being fit to all kinds of vehicles uses.
Description of drawings
Fig. 1 is an automobile engine starting control system structured flowchart.
The specific embodiment
Below in conjunction with accompanying drawing and specific embodiment; Further illustrate the utility model; Should understand these embodiment only be used to the utility model is described and be not used in the restriction the utility model scope; After having read the utility model, those skilled in the art all fall within the application's accompanying claims institute restricted portion to the modification of the various equivalent form of values of the utility model.
The utility model adopts the super capacitor of present main flow as the energy storage main devices, individual body capacitance 2.5V200F.Be divided into 2 groups every group 6 series connection, 2 groups in parallel connection then.Can be provided instantaneous large-current continuous and effective discharge time of 15V40A like this is 3 seconds.
Super capacitor energy-storage assembly negative terminal is used cross-sectional area 10mm
2Stranded conductor be connected with the storage battery negative terminal, anode is used cross-sectional area 10mm
2Stranded conductor be connected to the anode of storage battery through the relay for automobile of 12V40A.The adhesive of relay is controlled by Body control module.
Body control module is when detecting automobile engine starting, and the two ends that are incorporated into the storage battery power supply system to the relay of super capacitor energy-storage assembly through 40A replenish the electric energy of starter motor heavy-current discharge, reach big current compensation effect; After engine starting, the relay of Body control module control 40A continues adhesive and plays filter function; When engine off, Body control module discharge to break off the 40A relay, the super capacitor energy-storage assembly also just with the storage battery disconnection.This moment, the voltage of super capacitor energy-storage assembly was 14.2V; And the voltage of storage battery behind the engine off about 12.8V; Even being used, reduced the voltage of storage battery; Voltage in the super capacitor energy-storage assembly can not be affected, and still can provide powerful electric energy when starting next time, smoothly start the engine.
Claims (2)
1. automobile engine starting control system; Comprise super capacitor energy-storage assembly, storage battery, relay and Body control module; The positive pole of said super capacitor energy-storage assembly is connected condenser respectively with the positive pole of storage battery; The negative pole of said super capacitor energy-storage assembly connects the negative pole of storage battery, and said condenser also connects Body control module.
2. according to the said automobile engine starting control system of claim 1, it is characterized in that: said super capacitor energy-storage assembly comprises the super capacitor group of 2 groups of parallel connections, and every group of super capacitor group comprises 6 series connected super capacitors.
