Description
Technical field
This patent relates to the power supply circuits of electronic vehicle unit for automatic charging, relates in particular to the power supply circuits that adopt solar energy to supply power.
Background technology
The solar power supply circuit of existing electronic vehicle unit for automatic charging (OBU) comprises solar recharging branch road and energy storage device; The solar recharging branch road has solar-electricity source terminal and solar energy voltage stabilizing circuit, supplies sun-generated electric power through first voltage stabilizing circuit energy storage device to be charged; Energy storage device is responsible for each components and parts power supply.Because electronic vehicle unit for automatic charging need be in state at any time to be waken up, so power supply can not be interrupted.And well-known, solar energy is the unsettled energy of a kind of supply, so when the solar energy undersupply, will lean on described energy storage device electric energy stored when solar energy is supplied with abundance to continue each components and parts power supply.In order to let energy storage device can accept the burning voltage charging; Just need by described first voltage stabilizing circuit; This just causes when the solar energy undersupply; The first voltage stabilizing circuit output voltage is lower than the voltage of energy storage device, and first voltage stabilizing circuit will consume the electric energy of energy storage device on the contrary, causes waste of electric energy.
Summary of the invention
This patent is intended to solve electronic vehicle unit for automatic charging when the solar energy undersupply, and first voltage stabilizing circuit consumes the problem of the electric energy of energy storage device on the contrary.
Provide the solar power supply circuit of electronic vehicle unit for automatic charging for this reason; Comprise solar recharging branch road and energy storage device; The solar recharging branch road has solar-electricity source terminal and solar energy voltage stabilizing circuit, supplies sun-generated electric power through first voltage stabilizing circuit energy storage device to be charged; Energy storage device is characterized in that having the first unidirectional diversion member to be serially connected between first voltage stabilizing circuit and the energy storage device on the solar recharging branch road to each components and parts power supply, prevents that first voltage stabilizing circuit is applied in reverse voltage.
The serial connection first unidirectional diversion member between first voltage stabilizing circuit and energy storage device; First voltage stabilizing circuit just can not applied reverse voltage by energy storage device; Therefore when the solar energy undersupply; Energy storage device can't be to the charging of first voltage stabilizing circuit, and first voltage stabilizing circuit just can not consume the electric energy of energy storage device.
Description of drawings
Figure is the structured flowchart of electricity after vehicle unit for automatic charging inserts sun-generated electric power, back-up source.
Embodiment
Electronic vehicle unit for automatic charging adopts the solar power supply circuit among the figure; Solar power supply circuit has energy storage device; Have two charging paths arranged side by side to charge to energy storage device: first solar recharging branch road is formed by solar-electricity source terminal, first voltage stabilizing circuit and diode DS3 (as the first unidirectional diversion member) serial connection; It two is reserve charging paths, is formed by disposable battery and diode DS4 (as the second unidirectional diversion member) serial connection.
In the present embodiment, the burning voltage of first voltage stabilizing circuit output 4V, the pressure drop of diode DS3 is 0.12V, after the access sun-generated electric power, when solar energy is supplied with abundance, solar recharging branch road output charging voltage 3.88V; The disposable battery of employing 3.9V is power supply in support, and the pressure drop of diode DS4 is 0.12V, reserve charging paths output charging voltage 3.78V.
When solar energy is supplied with abundance,,, need not to consume the electric energy of back-up source so energy storage device is charged to 3.8V by sun-generated electric power because the charging voltage of solar recharging branch road output is higher than the charging voltage of reserve charging paths output.
When the solar energy undersupply, the solar recharging branch road can not be exported the charging voltage that is higher than the reserve charging paths, so energy storage device is backlogged power source charges, the assurance energy storage device can be kept certain voltage to each components and parts power supply.This moment, the first voltage stabilizing circuit output voltage was lower than energy storage device, but because diode DS3 is arranged, so energy storage device can't be to the charging of first voltage stabilizing circuit, first voltage stabilizing circuit just can not consume the electric energy of energy storage device.Diode DS3 also plays and prevents that first voltage stabilizing circuit was reversed the effect that electricity damages.Because adopt above-mentioned sun-generated electric power to have precedence over the design of back-up source; So when the energy storage device accumulate was sufficient, its voltage was higher than the voltage of reserve charging paths output, but because diode DS4 is arranged; Therefore can guarantee that back-up source can not charged by energy storage device; Just can not consume the electric energy of energy storage device, and, can prevent that disposable battery is recharged the situation that causes damaging and takes place for adopting disposable battery to make back-up source.
In order to let sun-generated electric power have precedence over back-up source energy storage device is charged; The charging voltage 3.88V that need be designed to the output of solar recharging branch road is higher than the charging voltage 3.78V of reserve charging paths output; Inserted diode DS4 in the present embodiment with step-down 0.12V effect; Make back-up source need have the voltage of 3.9V, the so then breakdown short circuit of contingency diode DS4, back-up source also can be by solar recharging branch road or energy storage device charging.
Energy storage device connects the existing systems power-supplying circuit through second voltage stabilizing circuit, and system's power-supplying circuit is waken up by existing wake-up circuit, each circuit (the comprising wake-up circuit) power supply in electronic vehicle unit for automatic charging.The effect of second voltage stabilizing circuit is to have stablized the voltage that energy storage device is externally supplied with each circuit, for example, has stablized the voltage of supplying with wake-up circuit, guarantees to wake up influence that sensitivity is not fluctuateed.
Described solar-electricity source terminal, first voltage stabilizing circuit, diode DS3, back-up source, diode DS4, energy storage device, second voltage stabilizing circuit and system's power-supplying circuit can be made on the circuit board, constitute solar powered administration module.
Preferably, the energy storage device in the present embodiment is a super capacitor, and benefit is: leakage current is little; The electric current that sparks is big; In its range of nominal tension, can be recharged, and can emit fully to any current potential; The traditional capacitor suitable with its volume compared and can be stored more energy, and the ultracapacitor that battery is suitable with its volume is compared and can be stored more energy; Transmission of power pulse and do not have any adverse effect repeatedly; Can quick charge and can not be compromised; Can circulate repeatedly hundreds thousand of times.
Diode in the present embodiment can wait other unidirectional diversion member to replace by for example controllable silicon (thyristor), for example, when adopting controllable silicon, can its grid be linked dc power anode or other high level place.By contrast, lower with the diode cost.
