3.1 battery electric vehicle BEV
electric vehicle with only a traction battery as power source for vehicle propulsion
3.2 cell block group of cells connected together in parallel configuration with or without protective devices, e.g. fuse or positive temperature coefficient resistor (PTC), not yet fitted with its final housing. terminal arrangement and electronic control device
3.3 hybrid electric vehicle HEV
vehicle with both a rechargeable energy storage system and a fuelled power source for propulsion
3.4 rated capacity cn capacity value of a cell in ampere hours (Ah) determined under specified conditions and declared by the cell manufacturer
4 Test conditions
4.1 General
The details of the instrumentation usea snaii De proviaea in any report ot results.
NOTE Test and measurement can be conducted under lixing conditions recommended by the cell manufacturer.
4.2 MeasurIng instruments
4.2.1 Range of measuring devices
The instruments used shall enable the values of voltage and current to be measured. The range of these instruments and measuring methods shall be chosen so as to ensure the accuracy specified for each test.
For analogue instruments, this implies that the readings shall be taken in the last third of the graduated scale.
Any other measuring instruments may be used provided they give an equivalent accuracy.
4.2.2 Voltage measurement
The resistance of the voltmeters used shall be at least 1 Mn/V.
4.2.3 Current measurement
The entire assembly of ammeter, shunt and leads shall be of an accuracy class of 0,5 or better.
4.2.4 Temperature measurements
The cell temperature shall be measured by use of a surface temperature measuring device capable of an equivalent scale definition and accuracy of calibration as specified in 4.2.1. The temperature should be measured at a location which most closely reflects the cell or cell block temperature. The temperature may be measured at additional appropriate locations, if necessary.
The examples for temperature measurement are shown in Figure 1. The instructions for temperature measurement specified by the cell manufacturer shall be followed.IEC 62660-2 pdf download.
