Description
Technical field
The utility model relates to a kind of power supervisor, especially relates to a kind of multifunctional electric power controller administering and maintaining for electromobile battery.
Background technology
Battery-driven car because of its environmental protection, easy to usely unprecedentedly popularized.According to authoritative department statistics, the social recoverable amount of 2012 China's battery-driven car in the end of the year is about 1.4 hundred million.Due to cost and technical limitation, electric vehicle power sources is still take lead-acid storage battery as main at present.The performance of the using method correctness of lead-acid storage battery on it and life-span impact are very large: overcharge and can make its heating temp raise, affect in-use performance, shorten service life, seriously overcharge and can make it fill to be bulgingly out of shape and to damage; Overload can affect its performance accelerated cure; Overdischarge meeting causes plate vulcanizing, seriously shortens service life.
For preventing that overcharging phenomenon occurs, the method adopting is at present to use intelligent charger (to be also three-step charger, end trikle charger etc.) charge a battery, and so-called intelligence is actually automatically reduces charging current in the time that electric weight is charged to 80% left and right, extend filling time, this scheme is actually the degree that reduces to overcharge in same charging duration, does not thoroughly stop to overcharge.And battery-driven car user is for exempting from trouble, be mostly charging in evening, one fills an evening, still exists so overcharge phenomenon.And recognize that the user who overcharges harm is for avoiding overcharging generation, and have to frequently go to check whether be full of in the time of charging, to cut off the electricity supply in time, additionally increase user's psychological pressure and trouble though reduced like this to overcharge.
For preventing that putting phenomenon occurred, manufacturer is all provided with voltage read out instrument on panel, grasps electric weight situation, to prevent overdischarge by user according to demonstration result.This is a kind of passive type safety method, only has user to pay attention to observe and the general situation of understanding electric weight with this is extrapolated and general ridden distance and prevention in advance just produces effect.Even if user has stronger consciousness of self-protection, can heightened awareness the harm of overdischarge, even on battery-driven car, under-voltage Warning light is bright (unless implementing power-off protection under undervoltage condition) also few people can accomplish to pay attention to and observe, be ready that gave up halfway uses simultaneously.From this angle, the ornamental practicality that is greater than of battery capacity indication instrument.
For over-current and-load, current battery-driven car is widely used protective tube or current limliting air switch is protected overcurrent.Protective tube is with low cost but be difficult to accomplish optimum matching, selects fusing less than normal frequently to affect use, and the starting current while startup as normal and the large electric current going up a slope when afterburning just likely blow a fuse; Select and bigger than normally do not have protective effect and still cause electrical motor or controller to burn.Protection switch also exist the problems referred to above and also sensitivity low, only pernicious short trouble is had to protection, controller and overheated the burning of excessive current flow in motor are not had to effective protective effect.
Existing controller for electric vehicle has over-current and-load defencive function, its principle is to install current sense resistor additional at loop of power circuit, in the time there is overcurrent, detecting ohmically loss in voltage increases, arrive the power tube control utmost point through inverse feedback, to reduce control voltage or the electric current of power tube, this method is owing to detecting the existence of resistance, during normal use both increased cal val, also reduced effective power output, in the time there is overcurrent, can only allow horsepower output pipe that conversion fast occurs between Push And Release, now the power consumption of power tube increases considerably on the contrary, can only there is jitter phenomenon and can not stop in car, and through using its protection of proof can't effectively distinguish startup, accelerate, afterburning normal current increases and fault current increase in short-term, so misoperation is frequent.
And once storage battery place in operation, its plate vulcanizing is just accompanied, transshipped to put and more aggravated sulfuration formation speed.Sulfuration causes chemical reaction slack-off, deposits electrical property and goes down, and badly influences charge-discharge performance and the in-use performance of storage battery.Current battery-driven car does not also have with it supporting sulfuration reparation, maintenance, elimination function.Therefore cause the desired life of lead-acid storage battery more than 5 years, but practical life are between 2-3.

Embodiment 5
The multifunctional electric power-supply controller of electric of the present embodiment, different from aforementioned each embodiment: to contain and eliminate plate vulcanizing circuit, described elimination plate vulcanizing circuit is by comparator IC4, resistance R 41-R46, capacitor C 41, C42 and diode D41, D42, power tube Q41, power inductance L1, L2 composition; It is oscillator that comparator IC4 is used for doing the signal generator of eliminating sulfuration required pulse.By IC4 and around element form spike signal generating circuit, the power output circuit of the signal control of generation take Q41 as core outwards exported instantaneous power spike.
Resistance R 42, DW41 composition mu balanced circuit provides stable voltage to eliminating plate vulcanizing circuit, and resistance R 41, R45 and R46 provide corresponding current potential to the in-phase input end of comparator IC4; The mouth control linkage power tube Q41 of comparator IC4, the drain electrode of power tube Q41 connects power end by diode D42, power input interface provides charging current to capacitor C 41 by diode D41, resistance R 44, resistance R 43, IC4 mouth provide the discharge loop of C41, afterflow inductance L 2 and reservoir capacitance C42 are connected to both ends of power, and power inductance L1 is connected between the drain electrode mouth and afterflow inductance L 2 and the connecting joint of reservoir capacitance C42 of power tube Q41.Described power tube can adopt bipolar transistor to replace.
Eliminate sulfuration circuit working process:
When storage battery is filled or electric weight approaches while draining, relay K is all powered adhesive, spike signal generating circuit is switched on power supply, because the in-phase input end current potential of IC4 is fixed, inverting input is connected to capacitor C 41, and the charge-discharge end of C41 is by its mouth control, its current potential that discharges and recharges by C41 is changed between high and low, the output of IC4 is also changed between height and active potential thus, power tube Q41 grid is controlled by IC4 output, causes conversion between conducting and cut-off between its source-drain electrode.
In the time of Q41 conducting, its electric current is from power supply BT positive pole, forms loop through inductance L 2, L1, Q41 drain electrode, source electrode to power supply BT negative pole, and in current flowing process, energy is stored by L1.
In the time that Q41 ends, due to inductance characteristic, the electric energy generation counter electromotive force formation pointed pulse being stored in L1 is outwards discharged, and its electric current, is got back to inductance L 1 through diode D42, power supply BT, capacitor C 42, node f and formed loop through node g from inductance.
Spike is added on storage battery through D42, and the pole plate in storage battery is formed to moment impact, smashes the sulfuric horizon forming on pole plate, reaches the object of eliminating sulfuration.
Due to this circuit formation is spike, its pulse width is extremely narrow, so require the discharge time constant of C41 much larger than charging time constant, the charging and discharging of C41 can not share same loop for this reason, in this circuit, provide charging current by D41, R44 to capacitor C 41, the discharge loop of C41 is provided by R43, IC4 mouth.The ratio of rationally getting R43 and R44 makes C41, and it discharges and recharges the requirement that the parameter such as spike, dutycycle that time constant forms meets the communications industry standard YD/T2064-2009 of the People's Republic of China (PRC) " communication lead-acid storage battery forward pointed pulse formula devulcanization equipment and technology condition ".In circuit, inductance L 42 has two effects.1, produce spike at circuit path is provided when storage battery is to capacitor C 42 supplementary electric weight later, so that electric capacity meets next time to inductance L 41 energy supplies, 2, produce and block it when spike and directly return to inductance L 41 and form loop at circuit, force it to form loop through storage battery the two poles of the earth to capacitor C 42.In circuit, the effect of D41 is that blocking-up C41 discharges through R41, meets the regulation of " standard " to extend discharge time.
In circuit, resistance R 12, R34, R46 all work the reversion effect of accelerating in the time that circuit reverses, and after reversion, make the current potential of this node to height or to lower step certain numerical value, make positive and negative reversal potential have certain return difference, make like this circuit working state after reversion can keep certain hour, be convenient to working stability.
The utility model multifunctional electric power-supply controller of electric, can realize following several functions:
In process of charging, the ascensional range of detection circuit monitors battery tension, in the time reaching full state, cuts off charge power supply, the generation that can thoroughly stop accumulator super-charge phenomenon.Or else user time also will remember and remove power cutoff with charging, eliminate trouble and the thought pressure of user's power cutoff.
Due to accumulator capacity, deposit the reason such as electric weight, power supply performance in real time, when vehicle overload is travelled, certainly will cause the aggravation damage battery polar plate of internal storage battery chemical reaction.In use electric process, the decline situation of detection circuit monitors battery tension, if overload can be exported loaded information signal driver buzzer phone sounding, prompting user car has been operated in overload condition, user can judge Reasons of Overload and get rid of according to actual conditions, once overload condition disappearance battery tension will go up, the blackout that gos up to exceed to overload after the prior predeterminated voltage of testing circuit, buzzer phone stops pronunciation.
If the not timely charging of user or car are in continuation is used, battery tension is along with the basic use of electric weight always continues to decline, once drop to the shutoff value setting in advance, now signal processing circuit will be exported control signal and goes to cut off the power supply of car or turn-off controller and force car stagnation of movement, connect sulfuration simultaneously and eliminate circuit working, prevent that storage battery from occurring sulfation at electric weight by most in the situation that, effectively avoids storage battery vulcanization.
Eliminate storage battery vulcanization circuit, guarantee that accumulator property, all the time in active state and activate accumulator capacity, improves battery-operated performance, eliminate the object of sulfuration.Work after storage battery is full of owing to eliminating sulfuration circuit, can eliminate storage battery and discharge and recharge last normal the and improper sulfuration producing in the cycle, delayed the aging of storage battery, effectively extended the service life of storage battery.
