Battery definition
Battery [1] is a kind of battery. Its function is to store limited electric energy and use it in a suitable place. Its working principle is to convert chemical energy into electric energy. It uses lead plate filled with spongy lead as negative electrode, lead plate filled with lead dioxide as positive electrode, and 1.28% dilute sulfuric acid as electrolyte. During charging, electric energy is converted into chemical energy, When discharging, the chemical energy is converted into electric energy. During discharging, the metal lead is the negative electrode, which is oxidized to lead sulfate; the lead dioxide is the positive electrode, which is reduced to lead sulfate. When the battery is charged with DC, the two poles generate lead and lead dioxide respectively. After removing the power supply, it returns to the state before discharging, Lead acid battery is a battery that can be recharged and discharged repeatedly. Its voltage is 2V. Usually, three lead acid batteries are used in series, and the voltage is 6V. Six [2] lead acid batteries are used in automobile to form 12V battery pack in series. Distilled water should be added to lead acid battery after using for a period of time, so that the electrolyte contains 22-28% dilute sulfuric acid, Electrode reaction: PbO2 + 4H + + SO42 - + 2E - = PbSO4 + 2H2O negative electrode reaction: Pb + SO42 -- 2e - = PbSO4 total reaction: PbO2 + Pb + 2h2so4 = = = 2pbso4 + 2H2O (right reaction is discharge, left reaction is charge)
Meaning of battery model 6-qw-68
6 stands for 6 grids, one grid is 2V. A total of 12V! Q is the first letter of the alphabet of "Qi" for starting. This letter stands for special use for cars, W is maintenance free. 68 is the battery capacity of 68A! Generally, the battery is maintenance free starting battery with voltage of 12V and capacity of 68A! The battery is also divided into positive and negative. Looking from the front, if the pile head of the right hand is negative, it means reverse installation, and if it is positive, it means positive installation. Remember to buy a battery
The meaning of battery model
What does 6-gd-120ah mean
"6" means that the battery is composed of six cells, because each cell is 2V, so the six cells are 12V, so the "6" particle is directly understood as a 12V battery
Q in "QA" means "starting type", a means "dry charged battery". It should be noted that "dry charged battery" does not mean dry battery, but is stored in the form of dry battery when it is not sold. When it is sold, the car can be started without charging 20 minutes after adding electrolyte
120ah refers to the capacity of the battery. Generally speaking, it means how much electricity it can hold
So together is: This is a 12 volt, dry charge battery for car starting, its capacity is 120ah

If there are many kinds of 200W solar cells, which parameters do I need, Then according to which parameters of the battery can the solar module charge the battery? To put it simply, I want the solar module to charge the battery. I need to know the parameters of the two? After reading some materials, I have some questions: 1. The motor power of electric bicycle seems to be more than 180W. The rated voltage of the battery is 36V, the working current is about 6a, the power of the battery is p = UI = 36 * 6 = 216w, so the working voltage of the motor is 36V, is the current 6A? (i.e. is the voltage and current of the battery the same as that of the motor?) 2. Charge the battery with solar cell array (36V, 12Ah). The voltage of solar cell array is about 51V [51V is according to the rule (12V (battery) - 17V (solar module), 24v-34v, 36v-51v)]. Is the current the working current of battery, that is, 6a left right? 3. Should the power of solar array be greater than or equal to the power of motor? 4. The solar array charges the battery. Can the controller realize the charging current of different stages required by the battery charging? 5. How does the speed of E-bike change?
