operating temperature.
         2.46. "Thermal runaway" means an uncontrolled increase of cell temperature caused by exothermic reactions inside the cell.
         2.47. "Thermal propagation" means the sequential occurrence of thermal runaway within a REESS triggered by thermal runaway of a cell in that REESS.
         2.48. "Type of REESS" means systems which do not differ significantly in such essential aspects as:
              (a) The manufacturer's trade name or mark;
              (b) The chemistry, capacity and physical dimensions of its cells;
              (c) The number of cells, the mode of connection of the cells and the physical support of the cells;
              (d) The construction, materials and physical dimensions of the casing and
              (e) The necessary ancillary devices for physical support, thermal management and electronic control.
         2.49. "Vehicle connector" means the device which is inserted into the vehicle inlet to supply electric energy to the vehicle from an external electric power supply.
         2.50. "Vehicle inlet" means the device on the externally chargeable vehicle into which the vehicle connector is inserted for the purpose of transferring electric energy from an external electric power supply.
         2.51. "Vehicle type" means vehicles which do not differ in such essential aspects as:
              (a) Installation of the electric power train and the galvanically connected high voltage bus;
              (b) Nature and type of electric power train and the galvanically connected high voltage components.
         2.52. "Venting" means the release of excessive internal pressure from cell or REESS subsystem or REESS in a manner intended by design to preclude rupture or explosion."
         2.53. "Working voltage" means the highest value of an electrical circuit voltage root-mean-square (rms), specified by the manufacturer, which may occur between any conductive parts in open circuit conditions or under normal operating condition. If the electrical circuit is divided by galvanic isolation, the working voltage is defined for each divided circuit, respectively.
3. Application for approval
         3.1. Part I: Approval of a vehicle type with regard to specific requirements for the electric power train.
         3.1.1. The application for approval of a vehicle type with regard to specific requirements for the electric power train shall be submitted by the vehicle manufacturer or by his duly accredited representative.
         3.1.2. It shall be accompanied by the under-mentioned documents in triplicate and following particulars:
         3.1.2.1. Detailed description of the vehicle type with regards to the electric power train and the high voltage bus galvanically connected to it.
         3.1.2.2. For vehicles with REESS, additional evidence showing that the REESS is in compliance with the requirements of paragraph 6. of this Regulation.
         3.1.3. A vehicle representative of the vehicle type to be approved shall be submitted to the Technical Service responsible for conducting the approval tests and, if applicable, at the manufacturer's discretion with the agreement of the Technical Service,
