Background technology
Along with the kind of vehicle electronic device is more and more, such as GPS terminal, vehicle electronics dog, radar for backing car, drive recorder, onboard navigation system etc., these vehicle electronic devices have brought various facilities to car owners, but such vehicle electronic device generally can not dispose independently electric power system at present, so mostly directly adopt automobile storage battery as their power supply.Along with increasing of the power consumption equipment of vehicle configuration, can cause the power supply pressure of automobile first wife storage battery constantly to increase.
Storage battery also is storage battery.Storage battery is a kind of of battery, and its operation principle is converted into electric energy to chemical energy exactly.Usually, the said storage battery of people refers to lead acid accumulator, is namely a kind ofly mainly made by lead and oxide thereof, and electrolyte is the storage battery of sulfuric acid solution.The effect of storage battery in automobile generally has following several:
One, when engine start, storage battery need to start the starting current of abrupt release up to 200A as the electric supply installation of start-up system, ignition system, electronic fuel injection system and other electric equipments of automobile;
Two, when engine stoping operation or low when idle, storage battery is to the automobile electrical power devices;
Three, when occurring the automobile electrical demand above the generator powered ability, storage battery participates in supplementary power;
Four, storage battery can play the effect of the voltage stabilizer of car load electric power system, can relax the surge voltage of electric power system, the electronic equipment on the protection automobile;
Five, when engine work, can be by to storage battery charging, generator is sent, unnecessary power storage behind the automobile normal consumption.
Above-mentioned the first situation is heavy-current discharge, and by contrast, four kinds of situations of second to five are low discharging current.Within the identical time, the storage battery heavy-current discharge is larger to the storage battery infringement than low discharging current.When main cause is heavy-current discharge, the lead sulfate degree of supersaturation that can form at the solid-liquid intersection of storage battery is large, thereby form more lead sulfate crystal and precipitation at the solid-liquid intersection, this not only can stop up the pole plate micropore, and obstruction dividing plate micropore, easier generation dendrite, in addition also can so that many crystallites when when discharge or charging, come off, thereby storage battery is damaged.Simultaneously, also can be owing to the diffusion velocity of sulfuric acid be slow, can only arrive the shallow-layer of electrolyte and more Alpha's brown lead oxide discharge is transformed, thereby make pole plate softening easily, cause the storage battery life-span greatly to reduce.
