Description

A kind of general rapid intelligent charger
Technical field
The utility model belongs to household appliance technical field, specifically relates to a kind of general rapid intelligent charger based on comprehensive detection and dynamic control.
Background technology
Along with The development in society and economy, increasing electrical equipment is come into daily life, the value volume and range of product of the low capacity storage battery that family uses all has significantly to be increased, if we mix a kind of charger for each storage battery, obviously can cause the great wasting of resources, and along with wearing out of storage battery, the variety of issue of appearance is also more and more, finally causes the decline of the life of storage battery.Increase (charger is also discarded thereupon) of waste battery understands greatly contaminated environment.Therefore, how research prolongs useful life of storage battery, and design, produces high-quality, high efficiency, meets the general rapid intelligent charger of family's instructions for use, and crucial meaning is arranged.
The charging process of battery can be divided into precharge, quick charge usually, supplies charging, the trickle charge four-stage.Pre-charge process is to make it satisfy certain charge condition with low current charge earlier during to long-term no or new battery charge.Quick charge recovers battery power rapidly as the term suggests be to use large current charge.Generally more than 1C, the time of filling fast is by battery capacity and charge rate decision for quick charge speed.Quick charge divides two kinds of constant current charge and pulse current charges, constant current charge be exactly with constant current to current charges, pulse current charge then be at first with pulse current to battery charge.Allow battery discharge then, so circulation.The amplitude of battery impulse is very big, narrower in width.The amplitude of common discharge pulse is about 3 times of charging pulse.For preventing that battery heating and the too much gas of inner generation charge with little electric current for a long time to it, long being of general process supplied charging.The subject matter of trikle charger is that charging rate is too slow, and for example, capacity is the battery of 1Ah, and when adopting the C10 charge rate, the charging interval is wanted more than the 10h.In most of trikle charger,, thereby after can not guaranteeing the battery full charge, turn-off charger immediately all without any voltage or Temperature Feedback control.
Can draw from nickel-cadmium cell quick charge characteristic, behind the full charge, cell voltage begins to descend, and the temperature and the internal pressure of battery rise rapidly, in order to guarantee that the battery full charge does not overcharge again, can adopt several different methods such as timing controlled, voltage control and temperature control:
-timing controlled:, be easy to determine the required charging interval according to the capacity and the charging current of battery.This control method is very simple, but because the initiation of charge state of battery is incomplete same, and the battery that has fills deficiency, therefore the battery overcharge that has, when having only charge rate less than 0.3C, just allows to adopt this method.
-voltage control: in the voltage control method, the easiest detection is the ceiling voltage of battery.Voltage control method commonly used has:
1) ceiling voltage (Vmax) method, from charging characteristic curve as can be seen, when cell voltage reached maximum, battery was a full charge.In the charging process, after cell voltage reaches setting, should stop quick charge immediately.The shortcoming of this control method is: the fully charged ceiling voltage of battery becomes with ambient temperature, charge rate, and the high charge of each cell is pressed difference is also arranged in the battery pack, therefore adopts this method can not judge very exactly that battery charges enough.
2) negative increment of voltage (Δ V) method because the absolute voltage of the negative increment of cell voltage and battery pack is irrelevant, and is not subjected to factor affecting such as ambient temperature and charge rate, therefore can be judged battery full charge more exactly.The shortcoming of this control method is: after negative increment appearred in cell voltage, battery overcharged, so the temperature of battery is higher.Behind the Ni-MH battery full charge, cell voltage will pass through the long period, negative increment just occurs in addition, and it is more serious to overcharge.Therefore, this control method mainly is applicable to nickel-cadmium cell.
3) voltage zero increment (0 Δ V) method, in the Ni-MH battery charger, the time that occurs negative increment of voltage for fear of wait passes of a specified duration and the damage battery, adopts 0 Δ V control method usually.The shortcoming of this method is: before the full charge, cell voltage may change very little in a certain period, stops quick charge prematurely thereby cause.For this reason, present most of Ni-MH battery quick chargers all adopt highly sensitive-0 Δ V to detect, and when cell voltage slightly reduces, stop quick charge immediately.
The control of-temperature: for fear of damaging battery, battery temperature is crossed when hanging down can not begin quick charge, after battery temperature rises to regulation numerical value, must stop quick charge immediately.Temperature-controlled process commonly used has:
1) in maximum temperature (Tmax) charging process, when battery temperature reaches 45 ℃, should stop quick charge immediately usually.The temperature of battery can detect by the thermistor that is fitted together with battery.The shortcoming of this method is that the response time of thermistor is longer, and temperature detection has certain hysteresis, and simultaneously, the maximum operating temperature of battery is relevant with ambient temperature.Cross when low when ambient temperature, behind the full charge, the temperature of battery does not reach 45 ℃ yet.
2) temperature rise (Δ T) can be adopted the temperature rise control method in order to eliminate environmental impact.After the temperature rise of battery reaches setting, stop quick charge immediately.In order to realize temperature rise control, must detect battery temperature and ambient temperature respectively with two thermistors.
3) behind rate of temperature change (Δ T/ Δ t) ni-mh and the nickel-cadmium cell full charge, battery temperature rises rapidly, and climbing speed Δ T/ Δ t is basic identical, when the battery temperature per minute rises 1 ℃ the time, should stop quick charge immediately, this charge control method is generally adopted in recent years.Should illustrate,, therefore, should manage to reduce the thermistor effect of nonlinear in order to improve accuracy of detection because the resistance and the temperature relation of thermistor are non-linear.
4) minimum temperature (Tmin) adopts big electric current quick charge when battery temperature is lower than 10 ℃, can influence the life-span of battery.In this case, charger should change trickle charge over to automatically, after the temperature for the treatment of battery rises to 10 ℃, changes quick charge again over to.
