Description
1. technical field
The utility model belongs to the vehicular automatic charge device of pure electric automobile.It is made of oil-electric engine group and ECU (Electrical Control Unit) etc., and being used for driving process can be for pure electric automobile automatic charging at any time, to solve the deficiency of pure electric automobile continual mileage.
2. background technology
As everyone knows, along with the aggravation of energy crisis and environmental pollution, oil price rises steadily, and traditional internal-combustion engines vehicle finally will be substituted by pure electric automobile.But this substituting still has many difficulties at present.Its reason just is that the energy resource system of present pure electric automobile also fails to find suitable power accumulator group.If still adopt the common lead acid accumulator, not only benzene is heavy, energy storage capacity is low, continual mileage is short; And charge consuming time many, useful life is short, lead contamination is serious; If use novel high-energy alkaline battery (such as nickel-hydrogen accumulator, lithium storage battery etc.) instead, although energy storage capacity increases to some extent, continual mileage is still shorter; And charging trouble and the more thoroughly solution of also failing consuming time; And adopt hydrogen oxygen fuel cell, zinc and air cell or solar cell at present still in test.Many cities are considering that in order to popularize pure electric automobile multiple spot arranges charging pile or storage battery is changed station etc. for this reason.
Between traditional combustion engine automobile and pure electric automobile, interim arrangement is to adopt hybrid vehicle or stroke-increasing electric automobile preferably.Wherein, hybrid vehicle is to install power accumulator and drive motors additional to form and be the automobile by internal combustion engine output in parallel with drive motors on the basis of traditional combustion engine automobile, and it in the process of moving or use internal combustion engine to drive automobile (being the ordinary internal combustion engine automobile this moment) by the mechanical transmission system; Perhaps use power accumulator group and drive motors and drive automobile (being pure electric automobile this moment).Stroke-increasing electric automobile then is to install the oil-electric engine group additional on the basis of pure electric automobile and the automobile that becomes oil-electric engine group and the output in parallel of power accumulator group, and it in the process of moving or use the power accumulator group to drive automobile (being pure electric automobile this moment) by drive motors; Perhaps use the oil-electric engine group to drive automobile (being stroke-increasing electric automobile this moment) by drive motors.Obviously, above-mentioned two kinds of hybrid vehicles or stroke-increasing electric automobile be owing to all needing to use the internal combustion engine drive automobile, thus its internal combustion engine not only discharge capacity and power are larger, and operating mode is changeable, and fails fundamentally significantly to reduce energy consumption and the discharging of automobile.
3. summary of the invention
Be subjected to the inspiration of orthodox car engine → generator → storage battery → starter motor, invention main points of the present utility model, be with the drive motors of starter motor as pure electric automobile, and be the automatic charge device (such as Fig. 1) that the equipped cover of existing pure electric automobile is made of vehicular oil-electric engine group and ECU (Electrical Control Unit).Not only the on-vehicle internal combustion engine generating set is connected in series with the power accumulator group and only is the usefulness of power accumulator group charging; And the keying of on-vehicle internal combustion engine generating set is controlled according to actual electric weight, terminal voltage or the charging current etc. of depositing of power accumulator group automatically by ECU (Electrical Control Unit).This car is only kept and is travelled with the electric weight of depositing of power accumulator group at ordinary times; If but the power accumulator group deposit the electric weight deficiency, just ECU (Electrical Control Unit) automatically starting apparatus combustion engine and generating set and be power accumulator group automatic charging, thereby keep pure electric automobile continue travel; Until when the power accumulator group was deposited the electricity abundance, ECU (Electrical Control Unit) was just closed down the oil-electric engine group automatically.Obviously, this pure electric automobile that is fitted with on-vehicle internal combustion engine generating set automatic charge device both had been different from the common pure electric automobile that the power accumulator group only is housed; Also be different from by internal combustion engine with the hybrid vehicle of power accumulator group output in parallel or by the stroke-increasing electric automobile of oil-electric engine group with the output in parallel of power accumulator group; More be different from traditional internal-combustion engines vehicle.It is compared with traditional internal-combustion engines vehicle and hybrid vehicle, because it can cancel machine driven system, thereby structure is simpler, and it is easier to reequip; It is compared with hybrid vehicle and stroke-increasing electric automobile, only charging for the power accumulator group owing to the oil-electric engine group that it was equipped with not is direct driving vehicle, thereby not only can reduce discharge capacity and the power of internal combustion engine, but also can make its operating mode all-the-time stable, thereby make effects of energy saving and emission reduction more obvious; It is compared with pure electric automobile, because it can make pure electric automobile only need to add in whole driving process to fill fuel and get final product automatic charging, not only continual mileage is unrestricted, and easy operation, thus the popularization that more is conducive to pure electric automobile with popularize.
