A new approach for the next generation of Superchargers

Posted on January 14, 2017

DC Fast Chargers are designed to charge electric vehicles quickly with an electric output ranging between 50 kW – 120 kW, like the Supercharger from Tesla. At a typical 400 volts, this results in a current of 300 amps. A new target is 350 kW resulting in a current of almost 900 amps. For this, a new approach is needed for the DC supply cables.


Two armour layers with separation

Posted on September 2, 2016

Calculating the ampacity of a cable system correctly starts with the precise modeling of the cable. The user shall be able to model a cable as close to reality as possible, visually, electrically and thermally. As a result from our participation at the Cigré 2016 in Paris, we have now introduced a separation layer between the two metallic armour layers.


Cyclic loading with daily, weekly, and yearly load factors

Posted on August 16, 2016

Using the Neher McGrath method for the calculation of the rating of buried cables under cyclic loading conditions allows for a daily, weekly, and yearly load factor in the same calculation.


Variation of spacing between sheath bonding points

Posted on July 3, 2016

For single-core cable circuits with sheaths solidly bonded at both ends and possibly at intermediate points, the circulating currents and the resulting losses increase as the spacing increases, and it is advisable to use as close a spacing as possible. The optimum spacing is achieved by considering both losses and mutual heating between cables.


Phase splitting

Posted on June 26, 2016

Phase splitting can be used to drastically reduce the magnetic fields of buried power cables. Also, the conductor cross-section can be less than half because the current is only half per split system and it can give a partial redundancy of about 60% or even more in case of a cable failure on one split system.

Cyclic loading

Posted on June 6, 2016

For the calculation of the rating of buried cables under cyclic loading conditions two main methods are used: The method according to IEC 60853 and the Neher McGrath method. The following post explains briefly the theory behind it and points out the additional features available in Cableizer.
