The manufacturer of an EV (electric vehicle) must be able to estimate exactly the available energy of a traction battery, because it corresponds to the driving range of his product. It is very important that a battery test procedure is developed which simulates the typical behaviour of an EV under actual conditions. It is therefore necessary to operate with cyclic power discharges. In an EV a particular power is required by the user without regard to the depth of discharge (DOD) of the battery. This aspect must be considered when establishing a new duty cycle. Such a duty cycle is developed from an analysis of the power profiles of an EV in urban traffic, which is probably the main operational area of an EV. The most important criteria for consideration when establishing a duty cycle are pointed out.
