When the REESS is mounted in a position which is between a line from the rear edge of the vehicle perpendicular to the centre line of the vehicle and 300 mm forward and parallel to this line, the manufacturer shall demonstrate the mechanical integrity performance of the REESS in the vehicle to the Technical Service.
The approval of a REESS tested under this paragraph shall be limited to specific vehicle type.
6.4.2.1.1. Vehicle based dynamic test
Compliance with the requirements of the acceptance criteria of paragraph 6.4.2.3 below may be demonstrated by REESS(s) installed in vehicles that have been subjected to a vehicle crash test in accordance with the Annex 3 to Regulation No 12 or 94 for frontal impact, and Annex 4 to Regulation No 95 for side impact. The ambient temperature and the SOC shall be in accordance with the said Regulations.
6.4.2.1.2. Vehicle specific component test
The test shall be conducted in accordance with Annex 8D to this Regulation.
The crush force replacing the prescribed force specified in paragraph 3.2.1 of Annex 8D shall be determined by the vehicle manufacturer using the data obtained from either actual crash tests or its simulation as specified in Annex 3 to Regulation No 12 or No 94 in the direction of travel and according to Annex 4 to Regulation No 95 in the direction horizontally perpendicular to the direction of travel. These forces shall be agreed by the Technical Service.
The manufacturers may, in agreement with the Technical Services, use forces derived from the data obtained from alternative crash test procedures, but these forces shall be equal to or greater than the forces that would result from using data in accordance with the Regulations specified above.
The manufacturer may define the relevant parts of the vehicle structure used for the mechanical protection of the REESS components. The test shall be conducted with the REESS mounted to this vehicle structure in a way which is representative of its mounting in the vehicle.
6.4.2.2. Component based test
The test shall be conducted in accordance with Annex 8D to this Regulation.
REESS approved according to this paragraph shall be mounted in a position which is between the two planes; (a) a vertical plane perpendicular to the centre line of the vehicle located 420 mm rearward from the front edge of the vehicle, and (b) a vertical plane perpendicular to the centre line of the vehicle located 300 mm forward from the rear edge of the vehicle.
The mounting restrictions shall be documented in Annex 6 — Part 2.
The crush force specified in paragraph 3.2.1 of Annex 8D may be replaced with the value declared by the manufacturer, where the crush force shall be documented in Annex 6, Part 2 as a mounting restriction. In this case, the vehicle manufacturer who uses such REESS shall demonstrate, during the process of approval for Part I of this Regulation, that the contact force to the REESS will not exceed the figure declared by the REESS manufacturer. Such force shall be determined by the vehicle manufacturer using the data obtained from either actual crash test or its simulation as specified in Annex 3 to Regulation No 12 or 94 in the direction of travel and according to Annex 4 to Regulation No 95 in the direction horizontally perpendicular to the direction of travel. These forces shall be agreed by the manufacturer together with the Technical Service.
The manufacturers may, in agreement with the Technical Services, use forces derived from the data obtained from alternative crash test procedures, but these forces shall be equal to or greater than the forces that would result from using data in accordance with the regulations specified above.
