Abstract

Full-automatic power generation for a 192V electric vehicle is applied to a 192V battery output circuit. In order to improve the stability of automatically starting a generator for power generation, a driver triode G2 is added for amplifying power and providing enough current for a relay on the basis of a voltage regulator triode G1; when a battery normally supplies electricity, the voltage regulator triode G1 enters a saturation region and does not work; when voltage of the battery is lower than a set value, the triode exits from the saturation region and enters a working state; and a collector of the triode couples a signal to the driver triode G2 through a coupling capacitor C5 to amplify the power and attracting current is provided for the relay to reach the target of automatically starting the generator for power generation. Positive electricity is output to a load circuit of the electric vehicle through a forward diode G3 by the electric quantity of the battery; and when the electric quantity (voltage) of the battery is lower than the set value 176V, the generator is automatically started for power generation, from the generated electricity, the direct current about 10 A is output to the battery through a diode G4, and the direct current which is up to 100A is output to the load circuit of the electric vehicle through a diode G5 to provide energy required by the 192V electric vehicle.

Description

192V electric motor car automatically generates electricity

Circuit operation principle:

In 192V storage battery output circuit, in order to improve the stability of automatic starter-generator generating, at G₁Voltage stabilizing On the basis of audion, add again G₂Driver triode, in order to power amplification, provides enough electric currents to relay.When Voltage stabilizing audion G during storage battery normal power supply₁Entering saturation region, this audion does not works, when battery voltage is less than setting value, This audion exits saturation region, enters duty, now by the colelctor electrode of this audion, by coupling electric capacity C₅Letter Number it is coupled to G₂Driver triode power amplification, provides operating current to reach the generating of automatic starter-generator to relay.Electricity The electricity of bottle is by forward diode G₃Positive electricity is exported, when the electricity (voltage) of storage battery is less than setting to electric motor car load circuit During definite value 176V, electromotor starts generating automatically, and the electricity sent is by diode G₄Direct current to storage battery output about 10A Electricity, diode G₅100A unidirectional current is exported, for energy needed for 192V electric motor car to electric motor car load circuit maximum.

Circuit advantage:

When the battery voltage of electric motor car is less than setting value, electromotor starts generating automatically, needed for charging for storage battery Small area analysis, supplies the most again the big electric current required for electric motor car load.

Art:

The present invention is applicable to electrocar, electric bus, railless electric train and storage battery power supply unit.

Technical background:

Few due to electric vehicle accumulator charge capacity at present, insufficient driving range, it is difficult to realize electric motor car and integrate with in automobile.

Summary of the invention:

For overcoming running distance of eletric vehicles not enough, when electric vehicle accumulator voltage is less than setting value, electromotor opens automatically Dynamic generating, is supplied respectively to energy needed for storage battery and electric motor car, it is ensured that electric motor car normally travels.

In storage battery power supply circuits, add forward diode, when electrical power generators, diode G₅Output voltage Higher than diode G₄Output voltage, due to the forward conduction characteristics of diode, at diode G₃Two ends produce two voltages, In order to the big electric current needed for the required small area analysis of storage battery charging and electric motor car.
