E-Mobility & High-Voltage Cleaning FAQs – Expert Answers from ZESTRON

Residues on high-voltage assemblies can cause leakage currents, arcing, and insulation breakdown. Proper cleaning reduces electrical risk and improves long-term system reliability.

Harmful residues include:

• Flux residues

• Ionic contamination

• Oils and cooling fluids

• Dust and particulates

These contaminants can compromise insulation resistance and electrical safety.

Common components include:

• Power electronics modules

• Inverters and converters

• Battery management systems

• Charging control units

All require high cleanliness to operate safely at elevated voltages.

Cleaning increases insulation resistance, reduces leakage currents, and prevents corrosion, helping protect both the electronics and end users.

Methods include:

• Aqueous and solvent-based cleaning

• Batch and inline systems

• Precision spray cleaning

The process depends on contamination type and voltage requirements.

Yes. Cleaning processes can be tested and qualified to ensure they meet insulation resistance and cleanliness targets before mass production.

Industries include:

• Electric vehicles (EV)

• Automotive electronics

• Renewable energy systems

• Power electronics manufacturing

• Charging infrastructure

Residues can cause leakage currents and insulation failure, creating safety and reliability risks.

When properly validated, cleaning processes are compatible with sensitive power components.

Yes. Proper cleaning significantly increases insulation resistance and electrical stability.
