High-voltage EV battery packs: benefits and challenges. More voltage

As with most things in engineering, arbitrarily increasing the pack voltage isn''t unequivocally a good thing, and that''s even without invoking a reductio ad absurdum argument (e.g. if 1 kV is better than 100 V, then 10 kV is better than 1 kV, etc.). Still, there are some benefits to increasing the pack voltage, and the most obvious is that less cross-sectional area in

High Current or High Voltage that damages components?

Excessive current results in excessive heat which will destroy both passive and active components. Some passive components, such as capacitors have a max voltage rating, which if exceeded can result in failure of the dielectric (insulator) resulting in excessive current, and ultimately smoke.

Definition of 18650 max current and influencing factors

For a high-efficiency 18650 lithium iron phosphate cell, it could have a high discharge or C-rate of up to 10C and for a standard 2700mAh battery, this means the 18650 max current could be as high as 27A. This max current rate could be maintained for as long as the rated maximum voltage isn''t exceeded which is regulated by the in-built BMS.

6 FAQs about [High voltage battery cabinet current is too large]

What happens if voltage is too high?

Too high a voltage tends to cause a catastrophic breakdown of a transistor. Once you apply over-voltage stress and the transistor breaks down, the pin will show short circuit (usually to ground). If you catch it, or limit the fault current some how, this type of failure will not be visible outside of the IC.

What happens if a capacitor is too high?

How does high voltage cycling affect battery performance?

High-voltage cycling is a direct driver of intercrystalline cracking, and higher voltages lead to the formation of many irreversible dislocations and cracks, which is detrimental to the performance of the battery.

What happens if a voltage rating is exceeded?

The matter of exceeding voltage ratings is also related to current, but in a different way. When the absolute max rating of a device is exceeded, the internal materials become conductors when they should be insulators, and now current flows in places and amounts not intended. This is commonly referred to as "Letting the smoke out".

Why is high voltage resistance important?

What happens if insulator voltage is too high?

When the voltage across an insulator gets too high, it is possible that the insulator will stop insulating and will instead start letting some current through. This current flow can cause damage. If voltages are high enough, dielectric breakdown can result in arcing, which can cause heating, pitting, etc.
