『An Open Letter to the Tesla Engineering and Safety Team』——Key Personal Findings Regarding Electric Vehicle Spontaneous Combustion Incidents
*************************************************************
Dear Tesla Engineering and Safety Team：
I am writing this letter not to question Tesla’s remarkable achievements in electric vehicle safety. On the contrary, it is precisely because Tesla leads the global EV industry in technology and safety that I believe your team has both the capability and the responsibility to lead the way in examining and addressing a long-overlooked physical issue.

This issue lies hidden within the EMI filters of every charging station, as well as under the "compliant" designs meeting the X-capacitor discharge requirements of IEC 62368-1, Clause 5.5.2.2.

In 2020, Professor Mingxing Zhu’s team at Hefei University of Technology published the research paper “Interaction Analysis of Three-Phase AC Charging Station LCL Filters under Grid Conditions.” Through modeling and experimental validation, the team pointed out that LCL filters often fail to achieve ideal filtering performance after commissioning, and the filter capacitors can even suffer severe damage. While the paper's data and conclusions are rigorous, a key question remains: why would a filter designed and certified according to international standards exhibit such vulnerability under normal grid conditions?

The answer directly relates to a compromise built into current standards. IEC 62368-1 requires X-capacitors to discharge to a safe voltage level within 5 seconds of power disconnection. To satisfy this static safety test while simultaneously meeting energy efficiency certifications, the industry generally selects very high values for discharge resistors. A 5-second discharge time equals roughly 500 times the half-cycle duration of mains power. The cost of this design choice is that the damping ratio ($\zeta$) is pushed extremely low, turning the system into an underdamped, high-voltage spring with virtually no buffering.

In this weakly damped state, dynamic conditions—such as power-on arcing, grid fluctuations, brownouts, and heavy load switching—easily excite high-frequency, high-voltage ringing spikes within the EMI filter circuit. Even with an inductance as small as $100\,\mu\text{H}$, a rate of current change on the order of $1\,\text{A}/10\,\text{ns}$ can generate significant high-voltage spikes. If recurring, these spikes subject not only the charging pile itself but also the vehicle’s BMS, communication chips, and insulation monitoring systems to cumulative electrical stress. Under specific circumstances, I infer that this could even produce a momentary, catastrophic impact that the entire system is ill-equipped to withstand.

I can reproduce this phenomenon using a simplified experiment: when a $0.47\,\mu\text{F}$ X-capacitor paired with a $10\,\text{M}\Omega$ discharge resistor is repeatedly plugged into and unplugged from a $230\,\text{V}$ AC outlet, a peak voltmeter captures spikes exceeding $554\,\text{V}$. Reducing the resistor value to $100\,\text{k}\Omega$ immediately and effectively suppresses these spikes. The underlying physics is straightforward.

Tesla’s fire and thermal runaway rates are significantly lower than the industry average, thanks to your team’s world-class BMS engineering in fault early-warning, pre-screening, and active intervention. In essence, Tesla uses a top-tier system to buffer the physical stresses originating from the charging side. However, even the most advanced BMS primarily detects and intercepts damage after it begins; it cannot stop uncontrolled ringing spikes from continuously generating at the source inside the charging station.

As an independent engineer with limited experimental resources, I cannot complete a full-chain attribution analysis connecting EMI uncontrolled ringing spikes to EV thermal runaway. Therefore, I offer here only the core, independently reproducible facts: EMI/X-capacitor circuits using large discharge resistors to meet current IEC standards do produce significant high-voltage ringing spikes during normal plugging/unplugging and grid transients (refer to the simplified experiment above and Prof. Zhu’s 2020 paper).

As to whether these spikes represent a significant or core contributing factor to EV thermal runaway, and whether it is necessary to supplement IEC 62368-1 with "dynamic damping safety" requirements, I respectfully ask the Tesla Engineering and Safety Team to reproduce these spike phenomena and evaluate the risks based on your fleet data, BMS logs, and root-cause analysis.

If Tesla is willing to confront this dynamic issue—long masked by static safety clauses—and drive standard setting bodies to add transient damping and spike suppression requirements alongside disconnection discharge safety, the entire industry will have the opportunity to mitigate risks at the charging interface and advance toward a higher level of safety. I look forward to seeing Tesla, as an industry leader, take the initiative to break this decades-old design paradigm.

Allow me to conclude with my personal perspective: As long as the physical conditions that trigger uncontrolled high-voltage ringing spikes exist, the possibility of related catastrophic events can never be entirely ruled out.

Sincerely,

SIMON MENG 2026.08.17

洪水从西藏冲下来，死了360多人、上千人失踪，中共却把它叫成“尼泊尔洪水”��
这太可怕了！出事几天前，有人已经拍到边境水电工地：不停爆破、碎石机狂转、悬崖上硬开隧道，安全几乎没有，环保更谈不上。Rasuwagadhi、Upper Trishuli 3A这些被冲毁的项目，背后都是中资或中企。

中共官方说是冰川崩塌堵河再溃决。撒谎不打草稿！整条河谷被当成工地在炸、在挖、在改河道，风险是被放大的。
西藏规划了上百座水电，吉隆口岸也在往冰川和地震带上硬开。电往东送，水往南泄。

上游现在又出现堰塞湖，随时可能二次溃决，下游尼泊尔、印度比哈尔就更完蛋了！

我的油管第7期：《在中国，千万别当好人》

在中国，千万别当好人。因为一扶，就得扶一辈子。

救人一命没有胜造七级浮屠，救人一命胜过七世糊涂。四川达州70岁蒋婆婆讹诈扶她的9岁小孩，索赔20万；沈阳70岁老太太敲诈救命恩人10万元；湖南常德老人摔倒却敲诈好心人3万元，祁东死者家属敲诈10万元。药店店主孙向波把一个存活率只有1%的老太太救回来，却被老太告上法庭，心力交瘁，落得生意关门。

中国不是没有好人，上面那些助人为乐的就是好人，但坏人横行，渐渐地好人也不敢做好事了。劣币驱逐良币……

晚清的时候，一批外国人来到中国，办医院、兴学校、开育婴堂。库姆斯放弃英国的优沃生活来到中国。义和团杀进学校，她用身体护住中国孩子，恳求义和团饶了那瘸腿的中国女孩一命。义和团就把她扔进火里，用石头砸……第二天，人们只找到她几块烧焦的骨头。

毕翰道来到中国，他和妻子为中国人做过数百例成功的白内障手术，让几百个中国人重新见到了光明。毓贤杀他时，毕翰道还在为毓贤祈祷，被一刀砍下了头颅。然后妻子的头被砍下，12岁的儿子的头也被砍下，每砍下一颗头颅，士兵们就把它沿街踢着玩，以示轻蔑。

那个从火里逃出来的英国传教士喊：山西大旱，我拿出五六万两银子，救活了几千人，你们连饶我一条命都不行吗。然后他被清军杀死。还有一个英国妇女抱着孩子跪下，说自己在这里行医，每年救活好几百人，求他们放过母子二人。士兵把她击倒，她和孩子一起被推进火里，活活烧死……连孕妇都被剁成碎块。

我们从不缺士为知己者死的个人报恩，比如荆轲、豫让、聂政。但从不鼓励公共领域的诚信、契约、感恩。因为士为知己者死，方便肉食者收买笼络。要是全社会形成诚信、契约、感恩，人民很容易团结起来，这就不好管理了。

这些年你是不是感觉坏人越来越多了，好人越发孤独了，这正是维稳制度想要的社会状态：人和人没有共识、没有友好协商，遇到坏人司法也不公正裁决，只要不影响统治，放出些小坏人，正是极权所想看到的，你忍气吞声，社会就和谐了，你据理力争，也只能去求政府，一切尽在掌控中。

原子化、散沙化、非共识化以及社会触感孤独化，是极权社会最理想的统治状态。最近几年，身边出现很多怪事儿，熟悉的朋友变怪了，熟悉的街道变怪了，熟悉的菜的味道也变了——不是它们变了，而是大环境变了，大环境一定要让你变成那条孤立无援的鱼。

自彭宇案后，见老人不敢扶，自崔英杰夏俊峰之后，见弱者被辱，不敢拔刀相助。其实是自韩非子以来，“侠以武犯禁，儒以文乱法”。身边的熟人越来越陌生，街上的事儿越来越怪了，可是你抬头，看那一片茫茫的原子化、散沙化，就知道，我们孤独的生活，就这么来的。

[黑洞視界｜Event Horizon: Tech’s Darkest Stain @simonmeng1995]

We once again earnestly urge the Tesla team to pay close attention to this hidden detail: the EMI filter within the charging station contains a component with a defect characterized by extremely low damping. Under sudden fluctuations, this component generates high-peak ringing disturbances, causing irreversible, cumulative damage to both the charging station and the vehicle. A more detailed article can be found here:

[黑洞視界｜Event Horizon: Tech’s Darkest Stain @simonmeng1995]

📯🌸The true technical root cause of spontaneous combustion risks in electric vehicles lies neither in the battery itself nor in the BMS, but rather in the charging station's EMI filter. Charging stations worldwide almost universally adhere strictly to Clause 5.5.2.2 of the IEC 62368-1 standard, which mandates that X-capacitors discharge to a safe voltage level within five seconds of power disconnection.
To meet this static requirement while simultaneously passing energy-efficiency certification, the discharge resistor (R) is selected at its maximum possible value. Consequently, the damping ratio (ζ) of the EMI filter is driven close to zero.
In a system with virtually no damping, events such as arcing during power-up, grid brownouts, or sudden large-load switching can generate voltage spikes and ringing reaching the order of ten thousand volts—far exceeding design safety margins. This is the physical "black hole" that subjects the BMS to repeated stress, ultimately leading to spontaneous combustion.
Are Tesla's Superchargers an exception to this?

[Capitán General de los Tercios @capTercio]

Hace 50 años, terroristas palestinos masacraron a 582 civiles cristianos en laciudad de Damour, en Libano.
Un sacerdote que sobrevivió a la masacre explicó: "Llegaban por miles gritando “¡Allahu Akbar! Mataron a todos: hombres, mujeres y niños".
Los hombres eran alineados contra las paredes de sus casas y fusilados. Las mujeres eran torturadas y violadas en grupo. Los bebés eran asesinados de un disparo en la nuca. A las mujeres embarazadas les extraían a sus bebés del vientre.
Así fue como los musulmanes pasaron a ser mayoría en el Líbano.
