Federations react to Exploding cells联合会作出反应,爆炸细胞 Categories - Industry, Events, Electric, Racing , trackback
Following up on the decision by the Norwegian federation to采取后续行动的决定,由挪威联邦 stop all EP racing停止所有的EP赛车 until the new year in response to the safety hazard of exploding NiMh cells, a number of other countries have also reacted, however so far not as strictly.直到新的一年里在回应安全的危险爆炸镍氢电池,其他一些国家也已作出反应,但是至今没有作为严格。 Neighbours Sweden decided to just ban a certain batch of the offending IB4200 cells, as have Belgium, and racing will continue as normal, while the BRCA in the UK have advised their members on the best way to handle, use and charge NiMh cells.邻国瑞典决定只是禁止某一批违法ib4200细胞,由于有比利时,和赛车将继续为正常,而brca ,在英国曾建议其成员就最佳的处理方法,使用及负责镍氢电池。 In the meantime the Intellect Battery Co. have now supplied the batch numbers which may contain cells that could potentially explode when subjected to race type conditions.在此期间,智能电池有限公司已经提供了一批数目可能含有细胞有可能发生爆炸时受到种族类型的条件。
Click here to read the list of affected cells and also the BRCA recommendations…请点击这里查看名单,受影响的细胞,也是brca建议…
The Intellect Battery Co. have now supplied the following cell Batch No’s., which may contain cells that could explode when subjected to race type conditions :-智能电池有限公司现已提供以下细胞一批没有的,可能含有细胞可能爆炸时受到种族类型的条件: -
ARAET, AZCWT, BNCWT, BNDST, BRAET, BZAWT. araet , azcwt , bncwt , bndst , braet , bzawt 。
We must stress that the Batch No’s.我们必须强调的是,一批没有的。 detailed have been compiled only from returns by European customers to Intellect.详细已汇编的回报只能从欧洲客户的智慧。 There may be other batches that we have not yet been notified of.可能还有其他的分批,我们尚未得到通知。 (So, do not assume that if a Batch No. is not detailed above, that it does not have any problem cells within it). (所以,不要以为如果第一批没有详细以上,它不会有任何问题细胞) 。 Some EU drivers obtain cells directly from USA, etc. and it is possible that batches outside the EU could also be affected which have not been notified to us.欧盟一些司机取得细胞直接来自美国,等等,并很可能分批欧盟以外的也可以受到影响,其中并没有通知我们。
Intellect supply the same cell in ‘Customer designed shrink’.智力供应相同的细胞在客户设计的收缩' 。 Intellect has not confirmed if the same Batch Codes are used on these versions of cells.智力并没有证实,如果同一批代码是用在这些版本的细胞。 Most of the reports that have been received appear to be relating to cells in the Intellect shrink.大部分的报告说,已收到似乎是有关的细胞中的智力萎缩。 Hopefully the above information will cover most of the problems.希望上述资料将涵盖大部分的问题。
No doubt you will have read or heard the stories of batteries exploding and that the Norwegian Federation has temporarily suspended all electric racing.毫无疑问,您将有阅读或听到的故事,电池爆炸,并认为挪威联邦已暂停所有电动赛车。 We have been monitoring these incidents but obtaining hard facts is not easy, making it difficult to draw any meaningful conclusions.我们一直在监测这些事件,但获得确凿的事实是不容易的,因此很难得出任何有意义的结论。
Given that there are thousands of cells in circulation, such incidents have been exceedingly rare in the past.由于有数以千计的细胞在市面流通,此类事件已极其罕见,在过去。 The only serious incident that has occurred to date in UK was when a receiver pack blew, that has permanently damaged a person’s eyesight.唯一的严重事件,已发生的日期,在英国时,接收包发生爆炸,已永久损坏一个人的视力。 Although there will have been more injuries caused by scalpels or super glue in eyes than caused from exploding cells, you still need to take care!虽然有将已更所造成的伤害解剖刀或超级胶水在眼睛比从爆炸造成的细胞,你仍然需要照顾!
The NiMh cells have a chemistry that allows the cell to ’self-discharge’ over a relatively short period, (days as opposed to weeks).该镍氢电池有化学,使细胞'自放电'超过一个相对短的时间内, (天作为反对周) 。 Lately, some of the 4200 cells seem to self-discharge more rapidly than other/previous versions.最近,一些对4200细胞似乎自放电的速度比其他/先前的版本。 More importantly the amount each individual cell within a pack discharges varies (ie cell 1 might be .9v, cell 2 .8v, cell 3 .9v, cell 4 .7v, etc.)更重要的金额,个别细胞内的一包排放的不同(即细胞一可能是0.9五,细胞2 0.8五,细胞3 0.9五,细胞4 0.7五,等等)
If charged in this state, some chargers will not know when to stop the charge process, as some cells are demanding to continue with the charge, whilst others could be over charged.如果被控在这个国家,有些充电器将不知道何时停止收费的过程中,由于部分细胞的要求,继续与负责,而其他人可以超过起诉。 It is also important to control the delta peak (voltage drop-off after completed charge) to a low value when charging.它也是重要的控制三角洲的高峰(电压落客后,完成收费) ,以低价值的时候收费。 Once the cell has achieved full charge, any further charging will produce gas.一旦细胞已取得全权负责,任何进一步的收费将产生气体。 The cells have a pressure vent, but if that is blocked or not working, the gas pressure could cause an explosion.细胞有一个发泄的压力,但如果是阻塞或不工作,气体压力可能会导致爆炸。
High charge rates will also produce more gas and reduce the cells useful life.高收费也将产生更多的气体,减少细胞的使用寿命。 It is possible that internal gas pressure may cause distortion to some internal parts that could result in a short circuit within the cell.是有可能的内部气体压力可能会导致失真的一些内部零件,可能会导致短路,内部的细胞。 An internal short circuit combined with gas pressure is likely to be a ‘big bang’.一内部短路结合气体压力可能是一个'大爆炸' 。
Drivers need to recognise that the ‘matchers’ recommendations are intended to achieve maximum performance.司机必须认识到' matchers的建议,目的是为了实现最大程度的表现。 It is the recommendation from the cell manufacturer that should be used.它是建议从细胞制造商应使用。
Best Practice for use of NiMH cells. 最佳实践的使用镍氢电池。
1. 1 。 Equalise cells before charging if they have been stored (with charge) for more than 2/3 days.均衡细胞前的收费,如果他们已储存(费)以上的2 / 3天。 If any of the cells in the pack show that they do not need to be equalised (ie the light does not show or goes out straight away) then remove the pack from the equaliser and charge for a short period (approx. 5 mins. should be adequate).如果有任何细胞,在包显示出他们并不需要成为equalised (即轻不显示或熄灭直线距离) ,然后再删除包从均衡,并负责为在短期内(约5分钟。应足够) 。 Then carry out the equalising process.然后进行有关的平等在过程中。
2. 2 。 Never exceed the manufacturers recommended fast charge rate.从来没有超过制造商建议的快速充电率。 This should be 1C max., even if the manufacturer states higher.这应该是1 C条最高,即使制造商国家更高。 (C being rate of charge based on capacity of the cell, eg a 4200 mAh cell = 4.2 amps) (三被率收费的基础上的能力的细胞,如4200 MAH的细胞= 4.2安培)
3. 3 。 Disregard any charge rate recommendations by the ‘matcher’ if it is more than 1C.无视收取任何费用率的建议,由'配对'如果是多于1 C条。
4. 4 。 Use a maximum Delta-Peak setting of 3mV per cell (6-cell pack = 3mV x 6 = 0.018V).使用最多的Delta -山顶设置3mv每个单元( 6细胞包= 3mv × 6 = 0.018v ) 。
5. 5 。 Never repeak cells after main charge.从来没有repeak细胞后,主要负责。
6. 6 。 Use a temperature cut-out as an additional safety feature set at 42 deg.使用温度削减了作为一个额外的安全功能,定于42华氏度。 C max., located on the hottest cell (usually middle cell). c最大,位于最热门的细胞(通常是中间细胞) 。 If charging on a cold day then consider reducing this to around 35 deg.如果收费就非一日之寒,然后考虑降低这是大约35度。 C.长
7. 7 。 Allow cells to fully cool to ambient temperature before further charges.让细胞充分冷却到常温前进一步指控。 Be aware the centre of the cell cools slower than the outer casing.知道该中心的细胞冷却慢,比外壳。 Do not put them in water to cool down; in an emergency cover the cells with a damp/wet cloth if you have to quickly cool them.不把他们在水中降温;在紧急情况下,包括细胞与潮湿/湿布如果您有迅速降温。
8. 8 。 Store cells with some charge (30/50%).存储细胞,与一些负责人(五十〇分之三十% ) 。

IB should be held responsible for the quality of their batteries.兴业须负上责任,为高质量的电池。 Has a lawsuit been placed for the person who has lost their site?已提出诉讼,被列入该人谁失去了他们的网站呢?
no lawsuits没有诉讼
The above reccomendations for nimh cell care, does this specifically apply to the IB4200 cells, or is it a good general guideline for all cells, such as GP3300’s, 3700’s, etc., etc. ???上述reccomendations为镍氢电池的照顾,这是否特别适用于ib4200细胞,抑或是一个很好的一般准则,为所有细胞,如gp3300的, 3700的,等等? ? ?
I think its more directed towards the IB42s as they are the batteries at the moment with the major “exploding” issues and so on.我认为它更针对ib42s因为他们是电池目前与主要的“爆炸”问题等等。 But its recommendations I would use on the GPs to keep them in top form to as ive seen GP cells explode to!但它的建议我会用对全球定位系统,使他们在顶端的形式,以作为香港专业教育学院看到GP的细胞爆炸!
[…] will soon release the follow up to the explosive power of their IB4200 cells with the introduction of the all new IB4600VR-1. [ … … ]将很快释放后续爆炸力他们的ib4200细胞与引进的所有新ib4600vr - 1 。 These new batteries not only […]这些新的电池,不仅[ … … ]
