EUROLAB, with its state-of-the-art accredited laboratories and expert team, provides precise and fast testing services within the scope of SAE J-1766 testing. Electric, Fuel Cell and Hybrid vehicles can contain many types of high voltage systems. Adequate barriers between occupants and high voltage systems are necessary to protect against potentially harmful electrical current and substances within the high voltage system that could cause injury to vehicle occupants during a collision.
This SAE Recommended Practice is applicable to all Electric, Fuel Cell and Hybrid vehicle designs consisting of at least one voltage bus rated voltage equal to or greater than 60 Volts DC or 30 VAC. This Recommended Practice addresses electrical insulation integrity, electrolyte spillage, and battery system containment.
The purpose of this standard is to define test methods and performance criteria that evaluate high voltage system spillage, battery retention, and electrical system insulation in Electric, Fuel Cell and Hybrid vehicles during specific crash tests.
The change to allowable isolation of fuel cells is based on the recognition that, unlike batteries, fuel cell stacks operate solely as DC systems that are not charged or fed back.
Fuel cell vehicles have aqueous coolant in direct contact with the fuel cell active area. The conductivity of this coolant is an important factor in the insulating properties of a fuel cell. The refrigerant conductivity increases with time which reduces the insulation. Fuel cells are expected to maintain a 125 ohm/volt isolation with aged coolant.
EUROLAB assists manufacturers with SAE J-1766 test compliance. Our test experts, with their professional working mission and principles, provide you, our manufacturers and suppliers, the best service and controlled testing process in our laboratories. Thanks to these services, businesses receive more effective, high-performance and quality testing services and provide safe, fast and uninterrupted service to their customers.
