火炬8V蓄电池适用电动巡逻车、电动观光车、电动高尔夫车、电动游览车、电动环卫车等电瓶车,以电瓶作为驱动力的新能源车辆,火炬8V140Ah/150AH电动车电瓶具备循环寿命长,特殊铅膏配方设计,深循环性能优异。大电流放电流性能优越,比功率高,起动,爬坡能力强。充电接受能力强,采用特殊合金配方,短时间实现快速充电。高低温性能优异, 在-20℃—60℃环境下正常使用,高温下安全性能强。安全可靠,超强外壳设计,耐震,抗冲击,密封可靠,决不漏液。温度对电动车电池充电性能的影响更加明显。目前的动力电池,在低温下充电的明显特点就是电压迅速上升。由于在低温下充电会带来许多问题,如锂离子电池,低温充电时,正极锂脱出快,负极锂向内部的嵌入速度慢,就会造成锂金属在电极表面的积累,生成枝晶,使电池短路。Ni/MH电池在低温充电时,由于贮氢负极对氢的吸收速度变慢,氢来不及被贮氢合金吸收,就会形成氢气,增大电池内压,影响到安全性能。目前无法从根本上解决电池的低温充电问题。混合电动汽车在实际应用中,车辆只要启动开来,随着电源系统的持续工作,电池组温度会逐渐上升,达到或接近常温,对电池组的充电影响不大。纯电动汽车在低温情况下充电时可以根据温度进行控制,前期采用小电流充电,随着充电的进行,电池组温度逐渐升高,充电接受能力上升,对正常使用的影响也较小。火炬牌铅酸蓄电池属于二次电池,在充电时将电能转化为化学能储存在电池内,在放电时将电池,内储存的化学能转换为电能供给用电设备;每使用一次(放电),用充电的方法可以使活性物质复原再进行放电,充电和放电能够反复多次,循环使用。火炬8V蓄电池主要由正极板、负极板、电解液、隔板、电池槽、电池盖、极柱、注液盖组成。正极板采用管式结构,负极板为板式结构,电池槽与电池盖之间热熔密封。
火炬8V蓄电池有两种一种是免维护蓄电池,一种是铅酸蓄电池。您可以根据自己的设备,选择相应的蓄电池使用。不同浓度硫酸的比重不同,是导致电解液分层的根本原因,电池静置,没有对流,不疼痛浓度的硫酸不能充分混合,导致电解液的分层,火炬蓄电池选择同等浓度*好的硫酸,避免了电解液的分层现象。蓄电池中的电解液像人体中的血液一样宝贵,电解液一旦丧失,就意味着电池报废了。电解液是由稀硫酸和水组成的。充电过程中,难以避免失水,充电模式不一样,失水也不一样。单只电池失水超过90克,电池就报废了。在常温下(25℃),普通充电器的失水量约为0.25克,而火炬蓄电池为0.12克。在高温下(35℃),普通充电器的失水量为0.5克,而火炬为0.23克。按此计算,普通充电器在250次循环后水分充干,火炬蓄电池在600次循环后水分才会充干。因此,火炬蓄电池能延长电池一倍以上的寿命。降低充电过程中的失水量,提高电池的使用寿命。火炬8V蓄电池通过充电过程,能够把电能转化成化学能储存起来,当需要使用电力时,蓄电池可以把储存的化学能转化为电能,向外进行输出,而这一转换过程是对于蓄电池来说是可逆的。
火炬电动车蓄电池的循环使用寿命是指以电动汽车电池充电和放电一次为一个循环,按一定测试标准,当电池容量降到某一规定值(一般规定为额定值的80%)以前,电池经历的充放电循环总次数。循环使用寿命是评价电池寿命性能的一项重要的指标。电动汽车动力电池循环次数越多,可用SoC范围越窄,电池的自放电率是指电池在存放期间容量的下降率,即电池无负荷时自身放电使容量损失的速度。自放电率用单位时间内容量下降的百分数表示。电池的输出效率电池实际上是一个能量存储器,充电时把电能转变为化学能储存起来,放电时再把化学能转变为电能释放出来,供用电装置使用。电池的输出效率通常用容量效率和能量效率来表示。电池的容量效率指电池放电时输出的容量与充电时输入的容量之比,电池的能量效率指电池放电时输出的能量与充电时输入的能量之比。通常,电池的能量效率为55%~75%,容量效率为65%~90%。对电动汽车而言,能量效率是比容量效率更重要的一个评价指标。电动观光车游览车的核心部位是蓄电池,游览车的续航能力以及里程都是有蓄电池的质量好坏决定的,因此蓄电池的日常维护非常重要,那么我们首先要了解蓄电池容易出故障的几个常见问题:在正、负极板之间通过一种特殊的微孔塑料隔离片加以绝缘,另外,在负极栅形极板外,加套一种专用薄膜,以防止由于充电,其活性物质泥膏因膨胀而脱落,造成与外界短路。从而保证了电池寿命长。火炬8V蓄电池适用于电动观光车,电动游览车,高尔夫球车,电动环卫车,电动搬运车等,是理想的动力电源,它具有寿命长瞬间电流大,重量比能量高,可充电接受性能好等特点。火炬8V电动车蓄电池型号为:4-EV-120(4-DG-140)。The 8V battery for electric cars, electric sightseeing cars, electric vehicles, electric vehicles, electric vehicles such as sanitation car battery, the battery as a new energy vehicle driving force, the torch 8V140Ah/150AH electric vehicle battery has long cycle life, special paste formula design, excellent performance of deep circulation. High current discharge performance, high specific power, starting, climbing ability. Strong ability to accept the charge, the use of special alloy formula, a short time to achieve fast charging. High and low temperature performance, in the -20 - 60 DEG C environment, the use of high temperature, high safety performance. Safe and reliable, super shell design, vibration proof, shock resistance, reliable sealing, no leakage. The effect of temperature on the charging performance of EV battery is more obvious. At present, the obvious characteristic of the power battery charging at low temperature is that the voltage rises rapidly. Due to the low temperature charging will bring many problems, such as lithium ion battery, low charge, positive electrode of lithium anode to internal out fast, the embedding speed is slow, it will cause the accumulation of lithium metal on the surface of the electrode, dendrite formation, short-circuit the battery. When the Ni/MH battery is charged at low temperature, the hydrogen absorption rate of the hydrogen storage anode is slow, and the hydrogen can not be absorbed by the hydrogen storage alloy, and hydrogen is formed, and the inner pressure of the battery is increased, which affects the safety performance. Currently can not solve the problem of low temperature battery charging. In the practical application of hybrid electric vehicles, as long as the vehicle starts to open, with the power system continues to work, the battery temperature will gradually rise to reach or close to room temperature, the battery charging little effect. Pure electric vehicle charging at low temperature can be controlled according to the temperature, the small current charging, with the charge, the battery temperature gradually increased, charge acceptance ability rise, impact on the normal use of the smaller. The card belongs to the two lead-acid battery battery in charging the electrical energy into chemical energy stored in the battery, the battery discharge, the stored chemical energy into electrical energy supply electrical equipment; a time (discharge), charging method can recover and discharge of the active substance charge and discharge, can be repeatedly recycled. The 8V battery is mainly composed of a positive plate, a negative plate, an electrolyte, a separator, a battery cell, a battery cover, a pole and a liquid injection cover. The positive plate adopts a tubular structure, and the negative plate is a plate type structure.
Torch 8V battery has two kinds of maintenance free battery, a lead-acid battery. You can according to their own equipment, select the appropriate battery use. The different proportion of different concentrations of sulfuric acid, causes the battery electrolyte stratification, static, no convection, no pain can not be fully mixed in sulfuric acid concentration, electrolyte stratification, torch battery sulfuric acid the same concentration of the best, to avoid the phenomenon of electrolyte layer. The electrolyte in the battery is as precious as the blood in the human body. Once the electrolyte is lost, it means the battery is dead. The electrolyte is composed of dilute sulfuric acid and water. Charging process, it is difficult to avoid dehydration, charging mode is not the same, dehydration is not the same. A single battery water loss of more than 90 grams, the battery will be scrapped. At normal temperature (25 degrees C), the average water loss of the charger is about 0.25 grams, while the torch battery is 0.12 grams. At high temperature (35 degrees C), the average water loss of the charger is 0.5 grams, while the torch is 0.23 grams. According to this calculation, the average charger after 250 cycles of water filling, torch battery in the water after the 600 cycle will be filled. Therefore, the torch battery can extend the battery life more than doubled. Reduce the amount of water loss in the charging process, improve the service life of the battery. The 8V battery through the charging process, can convert electric energy into chemical energy stored, when you need to use the electricity when the battery can store the chemical energy into electrical energy, outward output, and this conversion process is reversible for battery for.
The electric vehicle battery service life cycle refers to the electric vehicle battery charging and discharging time for a cycle, according to a certain standard test, when the battery capacity is reduced to a specified value (general provisions for the rating of 80%) before the battery charge and discharge cycle of the total number of experience. Cycle life is an important index to evaluate the performance of battery life. The number of electric vehicle battery cycle, the more narrow the range of available SoC, the battery self discharge rate refers to the battery during the storage capacity of the decline rate, that is, when the battery does not load the capacity of the capacity of the loss of speed. Percentage of self discharge rate per unit time. The output efficiency of the battery is in fact an energy storage device, which converts the electric energy into chemical energy when stored, and releases the chemical energy into electric energy when discharged. The output efficiency of the battery is usually expressed in terms of capacity efficiency and energy efficiency. The capacity efficiency of a battery is the ratio of the output capacity of the battery when the battery is discharged and the ratio of the input capacity. Generally, the energy efficiency of the battery is 55% to 75%, the capacity efficiency is from 65% to 90%. For electric vehicles, energy efficiency is more important than the capacity efficiency of an evaluation index. The core parts of electric sightseeing car tour car battery, car battery life mileage and the quality of battery are determined, so the battery daily maintenance is very important, so we must first understand the battery easily
