HeskonHeskon B2B Revisie

Repair and Diagnostics

As an independent service partner, Heskon provides safe and compliant repair services on behalf of the battery manufacturer or importer, fully in line with the requirements set out in the EU Battery Regulation (EU) 2023/1542.
Scalable B2B projects
From our European Service Center, 30+ trained battery specialists focus exclusively on lithium battery diagnostics and repair every day. Each year, we restore thousands of batteries for B2B projects.
Built-in data logging
During the production process, each battery is assigned a unique serial number and every step is recorded. This ensures that all modifications are stored digitally and can be linked to a battery passport.
Delivered by professionals
Our repair technicians can be trained quickly to work with your firmware and OEM spare parts, ensuring the original product’s quality and safety standards are maintained.

Repair of defective Li-ion batteries

With upcoming EU “Right to Repair” legislation, a reliable service partner is becoming crucial. Heskon can scale rapidly to support repair programs handling hundreds of batteries per week.

Collaboration on battery repair can include, for example:

  • Investigation, diagnostics, and reporting on failing products
  • Repair of defective components in the cell pack or BMS
  • Accurate SoH capacity testing for up to 50 batteries at a time
  • Rolling out firmware updates in series
