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.

Luggage compartment is the space in the vehicle fmsvs 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. Electrical isolation of a high voltage source in the vehicle means the electrical resistance between the high voltage source and any of the vehicle’s electrical chassis divided by the working voltage of the high voltage source.
High voltage source means any electric component which is contained in the electric power train or gmvss connected to the electric power train and has a working voltage greater than 30 VAC or 60 VDC. Each dummy is restrained only by means that are installed in the vehicle for protection at its seating position. Charge connector is a conductive device fmvs, by insertion into a vehicle charge inlet, fmvss an electrical connection of the vehicle to the external electric power supply for the purpose of transferring energy and exchanging information.
This includes, but is not limited to, a high voltage battery or battery pack, fuel cell stack, rechargeable energy storage device, and capacitor module.
United States Code U. 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. 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 that can become electrically energized under isolation fault conditions.
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 fmvsw high voltage source is a component contained in the power train.
When the vehicle is tested according to S6, the requirements of S5. The methods specified in S9.
S9 Test methods for physical barrier protection from electric fmvds due to direct and indirect contact with high voltage sources. This requirement does not apply under conditions where an internal combustion engine provides directly 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.
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. The symbol shown in Figure 6 shall be present on or near mfvss energy storage devices.
Voltages V1 and V2 are measured between the source and the electrical chassis. This device shall enable connection to the earth ground before exterior fmmvss is applied to the vehicle and retain the connection until after the exterior voltage is removed from the vehicle.
When leaving the vehicle, the driver shall be informed by an audible or visual signal if the vehicle is still in the possible active driving mode. The electric energy fmvsd device shall be at the state-of-charge specified in either subparagraph abor c:.
The vehicle must meet the requirements of S5. Before any vehicle impact test, Vb is equal to or greater than the nominal operating voltage as specified by the vehicle manufacturer.
FMVSS 305: Electrolyte spillage and electrical shock protection for electric-powered vehicles
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. 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. Electric energy storage device means a high voltage source that stores energy for vehicle propulsion.
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. 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.
The resistance between two exposed conductive parts of electrical protection barriers that are less than 2. Where a range is specified, the vehicle must be capable of meeting the requirements at all points within the range. 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.
VAC means volts of alternating current AC expressed using the root mean square value. During the measurement, the rechargeable electric energy storage system may be disconnected. 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.
External electric power supply is a power supply external to the vehicle that provides electric power to charge the electric energy storage device in the vehicle through the charge connector.
FMVSS Electrolyte spillage and electrical shock protection for electric-powered vehicles
Direct contact protection for a connector shall be provided by meeting the requirements specified in S5. In a test conducted under S6. During and after each test specified in S6 of this standard:. For a high voltage source that has an automatic disconnect that is physically contained within itself, the electrical isolation 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.
Fmvzs Law School Search Cornell. Live part is a conductive part of the vehicle that is electrically energized under normal vehicle operation. For a high voltage source that has an automatic disconnect that is not physically contained within itself, the voltage measurement after the test is made from both the high voltage source side of the automatic disconnect 35 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.
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. Fmvvss 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.
Markings are not required for electrical connectors or the vehicle charge inlet. This includes, but is not limited to, a high voltage battery or battery pack, rechargeable energy storage device, and capacitor module.
