水平电池常见问题回答 Frequently Questions Asked
Why can be fast recharge？
Bipolar structure which makes the current density is very uniform and higher charge efficiency.
Internal resistance 70% decreased compare to traditional battery ,which generates much lower heat during high current charging process(according to the resistance heating formula q = I * R* t, the heat value increases in square with the current).
The conductive cross section area is around 3 times of traditional which makes it can withstands much higher charge current.
Why it has super performance at high power output?
Bipolar structure which makes the current density is very uniform and higher utilization of active mass during high rate discharging.
Internal resistance 70% decreased compare to traditional battery ,which makes much lower voltage loss(around 1V per 12V) during high current discharging (according to the formula Vdis=V-I*R, lower resistance, lower voltage loss) ,thus it can discharge longer to a certain end off voltage.
The conductive cross section area is around 3 times of traditional which makes it can withstands much higher discharge current.
Why it has very low internal resistance?
Bipolar structure shorten the conductive distance and decreased the resistance.
Compared with the traditional monopolar battery structure, the special bipolar plates stacking layout eliminates the bus bar and cross bridge connection parts required between each cells inside, which not only greatly reduces the ohmic resistance, but also saves materials.
Why it has good cycle life?
Bipolar structure which makes the current density is very uniform and higher charge efficiency;
The composite pure lead grid is made by cold extruding process which makes several times corrosion resistance than normal casting technology.
Horizontal plates stacking eliminates the electrolyte stratification, which effectively improved the charging efficiency.
Special cyclic formula integrated, not only increased the cyclic capability but also improved the recovery performance after abuse over discharge.
Why it has good vibration resistance?
The special 3D serial and parallel connection structure between the internal cells makes the connection grid more firm and stable.
Horizontal plates with more than 60KPa assembling pressure, which effectively inhibits the shedding of active mass during vibration and cyclic.
Unique high-strength container structure design which is totally different form traditional, and extra added a 10mm thick herringbone stiffener at the bottom.
Why it has the best performance at extreme low temperature?
1、AGM技术, 贫液设计, 更耐低温。即电解液吸附于隔板，固态化，不具有流动性(液态更容易被冻住)；
AGM technology and starve design, more resistant to low temperature. That is, the electrolyte is adsorbed in AGM, which is like a solid state and has no fluidity (Popular saying “the liquid is easier to freeze than a solid”).
The internal resistance is very low, and the loss should smaller at low temperature (according to Vdis=V-I*R, the discharge platform decrease dramatically as the internal resistance increases greatly at low temperature, but the lower the basic internal resistance, the less voltage loss).
Bipolar structure which makes the current density is very uniform and higher utilization of active mass ,thus
higher discharge performance.
Super safe and reliable!
Starve design, electrolyte adsorbed in AGM, like a solid state, no liquid leakage even if the container is damaged.
The 3D series & parallel connection network between internal cells is composed of hundreds of lead wires, and it is impossible to completely damage all the connections due to any broken. As a result, as long as the battery is not completely broken, it will still maintain the normal voltage, only part of the broken capacity will be lost.
Excellent high power characteristic close to a super capacitor
The specific power density within 30S up to 700-1500W/Kg(Super capacitor ≥1000W/Kg )
Can be fast recharge with 3-10C at PSoC state.
How it can be maintenance free?
The essence of bipolar pure lead battery is still a valve regulated lead-acid battery, which is characterized by the use of new materials and new structure, so it has the same reaction principle as the ordinary AGM battery.
What is “stratification”?
1、蓄电池分层是由于电解液稀硫酸是水和酸的混合物，与所有混合物一样，其中H2SO4比H20重得多(H20的比重是1, H2SO4约1.84)，在重力的影响下，更重的物质有不断下沉的趋势。因此， H2SO4会向下逐渐沉淀并集中在底部。
Battery Stratification is caused by the fact that the electrolyte in the battery is a mixture of water and acid and, like all mixtures, one component, the acid, is heavier than water. Therefore, H2SO4 will begin to sink and concentrate at the bottom.
The higher the plates, the heavier the stratification phenomenon.
When charge ,the H2SO4 produced and make higher gravity around the reaction surface. and produced H2O during discharging to decreasethe gravity around. Thus accelerate the stratification during cycling.
This phenomenon exists in all types of lead-acid batteries.
Stratification can cause charge/discharge difference at different height of the plates and leads to sulphation and hard to recharge，finally reduced the performance & service life dramatically.
立放和卧放极板的区别Stratification phenomenon in vertical vs horizontal
The horizontal plate stacking of bipolar pure lead battery can effectively eliminate electrolyte stratification.
What is sulfation of a batteries?
Sulfation is the formation or deposit of lead sulfate on the surface of plates like a salt. If the sulfation becomes excessive and forms large crystals on the plates, the battery will not operate efficiently and may not work at all.
Does our battery has“Memory Effect”?
What is the “Memory Effect” that I have heard about?
Ni-Cad batteries and Ni-MH batteries, suffer from what's called the "memory effect". What this means is that if a battery is repeatedly only partially discharged before recharging, the battery "forgets" that it has the capacity to further discharge all the way down. To illustrate: If you, on a regular basis, fully charge your battery and then use only 50% of its capacity before the next recharge, eventually the battery will become unaware of its extra 50% capacity which has remained unused. The battery will remain functional, but only release 50% of its original capacity.
Does our battery has any“memory effect”？
No, a bipolar pure lead battery do not develop any type of memory effect.
