High-current charging technology - Quick charging of traction batteries

In each individual case, the implementation of the BELATRON (R) Quick Charging technology must be preceded by an analysis of the specific parameters. The throughput of battery capacity per shift and also the available standstill times are the most important criteria. It must be carefully examined whether enough time is left during a shift for the drawn battery capacity to be recharged. Unfortunately, there is no "recipe"; it is therefore recommended to first use battery controllers, e.g., IBAT (R) or BiCat (R) for determination of the exact data. The analysis following a representative working period then quickly shows whether the use of the BELATRON (R) Quick Charging System is profitable. Prior to the analysis of the data, the local conditions should be considered. Depending on the battery size, e.g., a sufficient connected load is required. An 80 V / 600 A charging unit requires approximately 60 kVA, corresponding to a line current of approximately 87 A per phase. If 15 units are used, this means that a total connected load of almost 1 MVA is required. Such connected loads are not available at every site! Furthermore, it is important to check whether the spatial conditions allow the installation of BELATRON (R) Quick Charging units. Not only must there be enough space. It must also be ensured that all legal and internal safety regulations are observed. These regulations will not be dealt with in this talk.
