A proven solution for tough electrical conducting challenges, the Bal Spring® canted coil spring helps designers efficiently manage more current while reducing system complexity and improving performance.
In electrical applications, the spring’s independent coils ensure multi-point contact for improved reliability, lower operating temperatures, and longer equipment life. The spring conducts higher amperages, exerts less wear, and exhibits less heat rise than other contact technologies. It automatically compensates for lateral and angular misalignment, as well as shock and vibration.
The multipurpose spring also shields equipment from the harmful effects of electromagnetic interference (EMI), providing superior attenuation in high-frequency, small package applications. As a mechanical fastening component, the Bal Spring performs latching, locking, and holding functions with insertion/removal forces that can be precisely controlled to >10,000 lb.

Bal Seal Engineering:
CharIN e.V. Member and Innovation Partner
Bal Seal Engineering, Inc., a regular member of CharIN e.V.’s international Amalgamation, is a leading global provider of custom-engineered, connecting, conducting, and EMI/RFI shielding and grounding solutions. In existing and emerging electric automotive platforms, the company’s Bal Spring® canted coil spring ensures reliable, consistent connection between battery packs, chargers, e-motors, inverters, regenerators, and other vehicle systems. The spring’s ability to manage high current in a small space without significant heat rise makes it an ideal component for designers who want to meet demand for faster charging times.
Jan Soede, General Manager for Bal Seal Engineering’s EMEA operations, says, “As a connecting specialist with decades of automotive experience, our company’s main goal in working with CharIN e.V. has been to collaborate in the future developments of the Combined Charging System to become the harmonized charging standard for electrical vehicles.”
Soede, who serves as his company’s representative in the Steering Group, recently conducted an in-depth webinar titled “Charging Ahead: How electrical contacts can accelerate fast-charging system design.” The 45-minute webinar focused on the emerging requirements of 350 kWh–1 MW+ fast-charge systems and driveline components. Other topics included:
• The role of advanced electrical contacts in reducing charge times and keeping temperatures down at higher amperages
• Contact selection criteria, including tolerance absorption capabilities, wear, power density, and form factor
• Common contact types and heat rise performance comparisons
• Contact scalability for “future proof” charging systems
• Strategies to remain aligned with current and future CCS1/2, and IEC/SAE standards for fast charging
