1.新买的电池,应该怎么充电啊?
1. buy a new battery, what should I charge?
  新电池只有在经过两、三次完全充电和放电的周期后才能达到最佳性能。建议前三次充电时间为4 小时(最长时间不要超过12小时;一般的锂电池都有保护电路,在充电3小时饱和后会自动保护,即使再充电和无法将电量充进电池;原来要求的新电池充电12小时,缺乏科学性),第四次开始,为使电池能充分充电,显示充满后可再多充1小时。
  New batteries only after two or three complete charge and discharge cycles in order to achieve the best performance. Recommends Qian three times charging time for 4 hours (most long time don't over 12 hours; General of lithium battery are has protection circuit, in charging 3 hours saturated Hou will automatically protection, even again charging and cannot will power filling into battery; original requirements of new battery charging 12 hours, lack scientific), fourth times began, for makes battery can full charging, displayed full Hou can again more filling 1 hours.
2.将电芯充满电存放,会对电芯性能造成影响吗?
2. store the batteries fully charged, will affect the battery performance?
  长期高电压储存会对电芯造成破坏。根据实验,电芯的储存时的电压不宜超过3.90V;储存电压越高,对电芯造成的不可逆容量损失就越大,容量恢复就越困难。而且,电压过高(>4.0V,电芯内部能量较大)会导致诸多安全问题。在生产、运输过程中,随时都可能因意外短路而引起事故。
  Long-term storage of high voltage will cause damage to the battery. According to the experiment, store when the voltage of the batteries should not exceed 3.90V; storage voltage, the higher the batteries causing irreversible capacity loss is larger capacity recovery more difficult. Moreover, the voltage is too high (>4.0V, batteries, internal energy larger) will cause many security problems. In the process of production, transportation, and at any time may be due to accidental short circuits and cause an accident.
3.成品电池存放一段时间之后,电压大幅下降,是什么原因?
3. finished batteries stored for a long time, the sharp drop in voltage, what is the reason?
  一般情况下,正常库存一个月允许电芯有不超过0.05V的自然掉电幅度。 如果超出此范围,则需对电池进行分析: A.检测电池保护电路各项保护参数是否正常,尤其是其静态自耗电应不大于10μA,(一般为3-6μA);可通过将高精度电流表(如FLUKE 187)串连接入“电芯-保护板B+/B-”回路,P+/P-空载,此时所显示的电流则为保护板的静态自耗电流。 B.分析电芯是否掉电严重。将电芯(充电之后)放电至3.0V,然后静置。下柜24小时以后测量开路电压,48小时候再次测量开路电压,进行对比。如果电压回升之后,有下降的趋势,则表明该电芯有掉电现象。遇到此情况时,可通过全检电压,挑出电压较低的电池,其余正常使用(由于电芯库存时间已经较长,存在掉电隐患的电芯可以完全挑出)。 C.检查电芯在正负极镍带点焊的过程中,是否有被击穿的现象。,过大的点焊电流、和不正确的点焊位置,都有可能击穿电芯内部、造成损伤,出现低电压现象。
  Under normal circumstances, the normal inventory for a month to allow the natural power of batteries does not exceed 0.05V. If beyond this range, is needed on battery for analysis: a,. detection battery protection circuit the protection parameter whether normal, especially its static since power should not is greater than 10 μ a,, (General for 3-6 μ a,); can through will high precision ammeter (as FLUKE 187) over access "electric core-protection board B+/B-" loop, P+/P-no-load, at by displayed of current is for Protection Board of static since power flow. B. analyze whether the batteries power seriously. Batteries (after charging) discharged to 3.0V, and can be replaced. Under Cabinet 24 hours later measuring the open circuit voltage, 48 hour%
