S1. Scope. This standard specifies requirements for limitation of electrolyte spillage and retention of electric energy storage/conversion devices during and after. NHTSA is issuing this final rule to amend Federal Motor Vehicle Safety Standard (FMVSS) No. , “Electric-powered vehicles: Electrolyte. FMVSS No. was originally drafted based on a voluntary consensus standard, the Society of Automotive Engineers (SAE) Recommended.

In addition to the conditions of S7. This includes, but is not limited to, a high voltage battery or battery pack, fuel cell stack, rechargeable energy storage device, and capacitor module. In addition, the resistance between an exposed conductive part of the electrical protection barrier of the high voltage source and any other simultaneously reachable fnvss conductive parts of electrical protection barriers within 2.
Electrical protection barrier is the part providing protection against direct contact with high voltage live parts from any direction of access. The resistance tester is connected to the measuring points the electrical chassis and any exposed conductive part of electrical protection barriers or any two simultaneously reachable exposed conductive parts of electrical protection barriers that are less than 2.
S9 Test methods for physical barrier protection from electric shock due to direct and indirect contact with high voltage sources. All measurements for calculating voltage s and electrical isolation are made after a minimum of 5 seconds after the vehicle comes to rest in tests specified in S6.
United States Code U. Spillage is measured from the time the vehicle ceases motion after a barrier impact test until 30 minutes thereafter, and throughout any static rollover after a barrier impact test. Cables for high voltage sources which are not located within electrical protection barriers shall be identified by having an outer covering with the color orange. High voltage source means any electric component which is contained in the electric power train or conductively connected to the electric power train and has a working voltage greater than 30 VAC or 60 VDC.
This includes parts under a cover, if the cover can be removed without using tools. Live part is a conductive part of the vehicle that is electrically energized under normal vehicle operation.
Prior to any impact test, the requirements of S5.
Working Voltage means the highest root mean square voltage of the voltage source, which may occur across its terminals or between its terminals and any conductive parts in open circuit conditions or under normal operating conditions. For a high voltage source that has an automatic disconnect that is physically contained within itself, the voltage measurement after the test is made from the side of the automatic disconnect connected to the electric power train or to the rest of the electric power train if the high voltage source is a component contained in the power train.
Automatic disconnect means a device that when triggered, conductively separates a high voltage source from the electric power train or the rest of the electric power train. Charge connector is a conductive device that, by insertion into a vehicle charge inlet, establishes an electrical connection of the vehicle to the external electric power supply for the purpose of transferring energy and exchanging information. Calculate the electrical isolation resistance Ri according to the formula shown.
Luggage compartment is the space in the vehicle for luggage accommodation, separated from the passenger compartment by the front or rear bulkhead and bounded by a roof, hood or trunk lidfloor, and side walls, as well as by electrical protection barriers provided for protecting the occupants from direct contact with high voltage live parts.
It is not guaranteed to be accurate or up-to-date, though we do refresh the database weekly. Markings are not required for electrical connectors or the vehicle charge inlet. In a test conducted under S6. The resistance between two exposed conductive parts of electrical protection barriers that are less than 2.
This includes, but is not limited to, a high voltage battery or battery pack, rechargeable energy storage device, and capacitor module. This standard applies to passenger cars, and to multipurpose passenger vehiclestrucks and buses with a GVWR of 4, kg or less, that use electrical propulsion components with working voltages more than 60 volts direct current VDC or 30 volts alternating current VACand whose speed attainable over a distance of 1. Possible active driving mode is the vehicle mode when application of pressure to the accelerator pedal or activation of an equivalent control or release of the brake system causes the electric power train to move the vehicle.
Electric energy storage device means a high voltage source that stores energy for vehicle propulsion.
Fmvs contact is the contact of persons with exposed conductive parts. A high voltage source that is conductively connected to an electric component which is conductively connected to the electrical chassis and has a working voltage less than or equal to 60 VDCis not required to meet the electrical isolation requirements in S5.
FMVSS 305: Electrolyte spillage and electrical shock protection for electric-powered vehicles
The symbol in Figure 6 shall also be visible on electrical protection barriers which, when removed, expose live parts of high voltage sources. For a high voltage source that has an automatic disconnect that is not physically contained within itself, the electrical isolation measurement after the test is made from both the high voltage source side of the automatic disconnect and from the side of the automatic disconnect connected to the electric power train or to the rest of fmvse electric power train if the high voltage source is a component contained in the power train.
The symbol shown in Figure 6 shall be fjvss on or near electric energy storage devices. The methods specified in S9.
FMVSS Electrolyte spillage and electrical shock protection for electric-powered vehicles
At the option of the manufacturer, protection against indirect contact with high voltage sources shall be determined using the test method in subparagraph a or subparagraph b. For a service disconnect which can be opened, disassembled, or removed without tools, protection degree IPXXB shall be provided when tested under procedures specified in S9.
For the purpose of determining the voltage level of the high voltage source specified in S5. During and after each test specified in S6 of this standard:. Where a range is specified, the vehicle must be capable of meeting the requirements at all points within the range.
Voltage Vb is measured across the two terminals of the voltage source. The system must monitor its own readiness and the warning display must be visible to the driver seated in the driver ‘s designated seating position. If the on-board electric energy storage device can be externally charged, vehicle movement of more than mm fjvss its own propulsion system shall not be possible as long as the charge connector of the external electric power supply is physically connected to the vehicle charge inlet in a manner that would permit charging of the electric energy storage fmvds.
More limitations on accuracy are described at the GPO site. Propulsion system means an assembly of electric or electro-mechanical components or circuits that propel the vehicle using the energy that is supplied by a high voltage source. If the probe partly or fully penetrates into the electrical protection barrier, it is placed in every possible position to evaluate contact with high voltage live parts.
Each dummy is restrained only by means that are installed in the vehicle for protection at mfvss seating position. VAC means volts of alternating current AC expressed using the root mean square value. Fuel cell system is a system mfvss the fuel cell stack sair processing system, fuel flow control system, exhaust system, thermal management system, and water management system.
When the vehicle is tested according to S6, the requirements of S5.
