Today's cars have not been able to drive away as much as they did many years ago, even if cheaper cars would have a complex electronic control system. For example, vehicle lights, fuel injection, ABS, EBD, ESP and so on, even the vehicle will need to launch electronic control system, unconsciously we have already entered the era of electronics. One thing was invented more than 100 years ago. Installed on the vehicle, although the rapid development of science and technology, but so far the car can not be less of its existence-heavy battery.
Seemingly ordinary things, but hidden mystery. We can often see the driver friend who was abandoned on the halfway because the battery was out of power. I have also met 2 times, Heavy Duty Battery Cell so the feeling of helplessness is not enough to mention the uncomfortable.
Soon back to the South days, the lower the temperature makes the battery more prone to failure, today I will give you a brief introduction of the battery daily precautions and maintenance common sense, by the way, Heavy Duty Battery Cell said the heavy battery this more than 100 years of story.
Why do cars have heavy batteries? What is the role?
The heavy battery is mainly responsible for starting the automobile engine and powering the vehicle's internal electric control system to ensure the normal operation of the vehicle. Heavy Duty Battery Cell Charging the generator on the engine when not in power and powering the electronic control system when the engine is not working.
(1) When starting the engine, the starter is provided with a strong starting current (generally up to 200-600a).
(2) When the generator is overloaded, it can assist the generator to power the electrical equipment.
(3) When the engine is idle, power to the electrical equipment.
(4) When the voltage of generator end is higher than that of lead heavy battery, Heavy Duty Battery Cell a part of electric energy is converted into chemical energy, which is to be recharged.
(5) Heavy-duty battery or a large-capacity capacitor, can protect the car's electrical appliances.
Classification of heavy-duty batteries
Classification and features of heavy-duty batteries
1 Ordinary heavy battery
The plate of the ordinary heavy battery is composed of the oxides of lead and lead, Heavy Duty Battery Cell and the electrolyte is the aqueous solution of sulfuric acid. Its main advantages are voltage stability, cheap price, the disadvantage is lower than the energy (that is, each kg of heavy battery storage), short service life and frequent maintenance.
2 Heavy Duty Batteries
Its full name is dry-type charged lead-acid heavy battery, its main feature is the negative plate has a higher storage capacity, in a completely dry state, Heavy Duty Battery Cell can be in two years to save the electricity received, when used, just add electrolyte, wait 20-30 minutes can be used.
3 Maintenance-Free heavy battery
Maintenance-free heavy battery because of its own structural advantages, the consumption of electrolyte is very small, in the service life of the basic need not add distilled water. It also has the characteristics of shock resistance, high temperature resistance, small volume and small self-discharge. Heavy Duty Battery Cell The service life is usually twice times of the ordinary heavy battery.
The principle of heavy battery
Heavy battery lead-acid heavy battery is composed of positive and negative plate, clapboard, shell, electrolyte and wiring pile, and the reaction of discharge is based on active substance of cathode plate and active substance of anode plate under the action of electrolyte.
The basic principle of heavy battery is to convert chemical energy into electric energy when discharging, and convert electric energy into chemical energy when charging. It's a bit awkward to read! Look at the following equation:
(an electrode that takes place in an oxidation reaction, an electrode that receives electrons from the reactants)
(The electrode in which the reaction occurs, Heavy Duty Battery Cell the electrode on which the reactant obtains electrons)
(cathode refers to the lower potential of the power supply, the physical electron outflow pole)
(cathode refers to one end of the power supply with a higher potential, a physical electron influx)
When the battery is discharged, the metal lead is the negative electrode, and the oxidation reaction is oxidized to lead sulfate;
When the battery is charged with direct current, the Poles generate lead and lead dioxide respectively.
When the power is removed, it reverts to the state before discharge, forming a chemical battery of internal homeostasis.
