FMVSS 305 PDF

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.

Electrical chassis means conductive parts of the vehicle fnvss electrical potential is taken as reference and which are: For motor vehicles with an electric energy storage device that can be charged through a conductive connection with a grounded external electric power supplya device to enable conductive connection of the electrical chassis to the earth ground shall be provided.

S9 Test methods for physical barrier protection from electric shock due to direct and indirect contact with high voltage sources. During the measurement, the rechargeable electric energy storage system may be disconnected. Not more than 5. Exposed conductive part is the conductive part that can be touched under the provisions of the IPXXB protection degree and that is not normally energized, but fmvs can become electrically energized under isolation fault conditions.

It is not guaranteed to be accurate or up-to-date, though we do refresh the database weekly. This includes, but is not limited to, a high voltage battery or battery pack, rechargeable energy storage device, and capacitor module. The vehicle must meet the requirements of S5. 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 rmvss volts alternating current VACand whose speed attainable over a distance of 1.

The electrical isolation is measured at the high voltage live parts of the vehicle charge inlet and determined in accordance with the procedure specified in S7.

Prior to any impact test, the requirements of S5. 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. In addition, the resistance between an exposed conductive part of the electrical protection barrier of the high voltage source and any other simultaneously reachable exposed conductive parts of electrical protection barriers within 2.

FMVSS 305: Electrolyte spillage and electrical shock protection for electric-powered vehicles

This includes, but is not limited to, a high voltage battery or battery pack, fuel cell stack, rechargeable energy storage fkvss, and capacitor module. 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 fmmvss open circuit conditions or under normal operating conditions.

When leaving the vehicle, the driver fmsvs be informed by an audible or visual signal if the vehicle is still in the possible active driving mode. 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.

When the vehicle is tested according to S6, the requirements of S5.

Fuel cell system is a system containing the fuel cell stack sair processing system, fuel flow control system, exhaust system, thermal management system, and water management system. More limitations on accuracy are described at the GPO site.

Cornell Law School Search Cornell. Direct contact protection for a connector shall be provided by meeting the requirements specified in S5. The symbol in Figure 6 shall also be visible on electrical protection barriers which, when removed, expose live parts of high voltage sources.

Where a range is specified, the vehicle must be capable of meeting the requirements at all points within the range. Automatic disconnect means a device that when triggered, conductively separates a high voltage source from the electric power train or fjvss rest of the electric power train.

The electrical isolation of a high voltage sourcedetermined in accordance with the procedure specified in S7. Live part is a conductive part of the vehicle that is electrically energized under normal vehicle operation. Direct contact protection for a vehicle charge inlet shall be provided by meeting the requirements specified in S5. Cables for high voltage sources which are not located within electrical protection barriers shall be identified by having an outer fmss with the color orange.

VAC means volts of alternating current AC expressed using the root mean square value. This requirement does not apply under conditions where an internal combustion engine provides fmvsa or indirectly the vehicle’s propulsion power when the vehicle is first placed in a possible active driving mode after manual activation of the propulsion system. 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 the electric power train if the high voltage source is a component contained in the power train.

FMVSS Electrolyte spillage and electrical shock protection for electric-powered vehicles

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.

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.

Vehicle charge inlet is the device on the electric vehicle into which the charge connector is inserted for the purpose of transferring energy and exchanging information from an external electric power supply.

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.

This includes parts under a cover, if the cover can be removed without using tools. This includes, but is not limited to, high voltage batteries or battery packs, fuel cell stacks, rechargeable energy storage systems, capacitor modules, inverters, interconnects, and venting systems.

Electrical protection barrier is the part providing protection against direct contact with high voltage live parts from any direction of access. United States Code U. For the purpose of determining the voltage level fmmvss the high voltage source specified in S5. Voltage Vb is measured across the two terminals of the voltage source.

Passenger compartment is the space for occupant accommodation that is bounded by the roof, floor, side walls, doors, outside glazing, front bulkhead and rear bulkhead or rear gate, as well as electrical protection barriers provided for protecting the occupants dmvss direct contact with high voltage live parts.
