One of the major drawbacks of electric cars is the time they take to charge in comparison to the time it takes to refuel a petrol or diesel vehicle. However, now one company believes it has made a significant breakthrough.
BRUSA Elektronik AG will produce an on-board battery charger for electric vehicles that uses a three-phase current with power up to 22kW, known as the NLG6 (pictured). It is able to fully charge the pack in a typical battery electric car in less than one hour.
Typically, the charging time of an electric car is determined by the size of the battery pack and the power of the charger. The battery pack will vary dependent on the electric car and typically the on-board chargers have a maximum power of 3.7kW – with charging times from six- to eight hours.
By contrast, BRUSA is offering fast charging with the power of 22kW – which was previously only possible using off-board DC charging infrastructure. That’s because BRUSA has been able to integrate the power electronics within a single and compact device.
It requires no off-board infrastructure and can usually be used with three-phase power supplies. Most modern house connections and public charging points are already equipped with the necessary power supply.
In addition, the charger comes with a host of safety measures.
It is believed that cars from a major European carmaker will include this charger before the end of the year.
