Abstract
The invention relates to an automatic charging device for multiple battery packs of a vehicle-mounted special battery. The special battery is a lithium ion power battery with the negative electrode made of a lithium titanate material, the vehicle-mounted battery is a battery with the same quality and is arranged in the vehicle in a way of two or three packs of structures individually, the automatic charging device is used for automatically simultaneously charging the corresponding vehicle-mounted multiple battery packs through non-manual operation, and comprises a contact resistance judgment circuit, charging loops, a switch circuit and a power measurement circuit, and the circuits are electrically connected. By applying the automatic charging device, the safety hidden danger to the human body caused by high pressure is completely eliminated, the operation efficiency is improved and the daily maintenance cost is lowered.
Description
Technical field
The present invention relates to a kind of charging device, exactly, relate to a kind of vehicle-mounted special cells many automatic battery chargers device.
Background technology
Along with new forms of energy development in science and technology, present electric automobile and following electric track train are all using electrokinetic cell to drive power supply as the most independent, mathematical be the running voltage of these power supplys be nearly all the high-tension electricity of direct current more than 300 volts even as high as direct current 750 volts, this causes great hidden danger to personal safety, although taking many technical measures, but for current effect, still there are some uncontrollable potential problems.
One feature of battery is to carry out running voltage combined capacity flexibly, if vehicle load kind is more, it is necessarily required to multiple running voltage power supply match with it, past is due to the unified power supply of main line electrical network, have to configure a series of power conversion system be allowed to and each load matched, owing to any converting system all exists a conversion efficiency problem, virtually cause energy resource consumption, use the separate power supply mode of many set of cells, it is possible to be obviously improved vehicle energy service efficiency.
For security consideration and the artificial repair and maintenance cost of reduction, here have devised a kind of multichannel automatic charge device, automatically electricity principle it is subject to reference to trolleybus and bullet train, realizing multichannel automatic charging, for a change, device is strictly limited by regional space distance, all processes must be carried out in the environment of unmanned the interference, acquire a certain degree of difficulty, including environmental impact factor, so there being certain scientific and technological content.
Summary of the invention
The present invention relates to a kind of vehicle-mounted special cells many automatic battery chargers device, special cells be negative material be the lithium-ion-power cell of lithium titanate material, on-vehicle battery is same quality battery to be arranged in car body so that two groups or three groups of structures are separate, automatic charge device refers to that unartificial operation is the most corresponding and charges to vehicle-mounted many set of cells, including contact resistance decision circuitry, each charge circuit, on-off circuit, electric quantity metering circuit, between each circuit, realize electrical connection.
The present invention brings and provides the benefit that, has thoroughly stopped the potential safety hazard that the person is brought by high pressure, improves operational efficiency and reduces daily repair and maintenance cost.
Further illustrate below by specific embodiment.
Fig. 1 is a public transport big bus example structure schematic diagram of the present invention.
In figure, 10: power supply；20: contact net；30: pantograph；40: set of cells.
nullPower supply (10) provides the output of two-way DC source，Two output voltage is all 600V，Starting is all constant current 150A，Identical two set of cells (40) of capacity specifications that the configuration of public transport big bus is separate，Design upper voltage limit is all 600V，Whole automatic charging process is that car is rested in roadside and fixes on parking stall by driver，Corresponding facedown charging pile by the road is positioned at big bus upper rear，Panel type contact net (20) road each with big bus roof pantograph (30) effectively contacts，After the powered-down personnel of vehicle leave，Charging pile detects contact resistance automatically，If contact resistance exceedes setting safety value i.e. alarm failure，When only meeting safe charging contact resistance value，Whole charge circuit could turn on and start to charge up，Two charge circuits are separate，Along with the charging interval elapses，The voltage of each set of cells self can gradually rise convergence charge power supply voltage，After certain pressure reduction，Constant current will no longer keep，But it is more and more less，When time is up must stop charging time，Whether it is full of to automatically power off and opens car door，Contact mechanism separates，Charge volume continuous data automatically saves，Charging interval is determined by daily headway substantially，Length is had to have short，The general charging interval is designed as about 10 minutes.
Fig. 2 is a track train example structure schematic diagram of the present invention.
In figure, 11: power supply；21: contact net；31: pantograph；41: set of cells.
nullPower supply (11) provides three-way direct current power supply output，Wherein two output voltage 750V，3rd road output voltage 110V，Track train configures three set of cells (41) that separate capacity specifications is different in headstock，Wherein two groups of design upper voltage limits are all 750V，One group of design upper voltage limit is 110V，Whole automatic charging process be driver car is parked in locomotive stop protect base fix repair and maintenance position，Panel type contact net (21) it is above locomotive，Can automatic lifting effectively contact with locomotive Ding Ge road pantograph (31)，After the powered-down personnel of locomotive leave，Charging system detects contact resistance automatically，If contact resistance exceedes setting safety value i.e. alarm failure，When only meeting safe charging contact resistance value，Whole charge circuit could turn on and start to charge up，Three charge circuits are separate，Along with the charging interval elapses，The voltage of each set of cells self can gradually rise convergence charge power supply voltage，After certain pressure reduction，Constant current will no longer keep，But it is more and more less，When time is up must stop charging time，Whether it is full of to automatically power off and opens car door，Contact mechanism separates，Charge volume continuous data automatically saves，Charging interval is determined by daily headway substantially，Length is had to have short，The general charging interval is designed as about 10 minutes.
