Compared to today’s electric vehicle chargers, they have managed to shorten the charging time from eight to two hours, and to reduce the cost by around $2,000
Researchers at Chalmers have developed a unique integrated motor drive and battery charger for electric vehicles. Compared to today’s electric vehicle chargers, they have managed to shorten the charging time from eight to two hours, and to reduce the cost by around $2,000.
Saeid Haghbin, doctor of electric power engineering, undertook his doctoral studies in order to develop the optimal electric vehicle charger. The result is a novel high-power integrated motor drive and battery charger for vehicle applications, where a new power transfer method has been introduced involving what is known as a rotating transformer.
“The ideal scenario would be to have a charger powerful enough to charge a car in five to ten minutes, but this would cost over $100,000, which is more expensive than the car itself,” says Saeid Haghbin. “The question we posed was: how can we reduce the size, weight and price of the on-board charger”.
Since the electric motor and the inverter are not used during battery charging, the researchers looked into the possibility of using them in the charger circuit and building some kind of integrated motor and battery charger. In other words, would it be possible to use the motor and inverter in the charger circuit to increase the charging power at a lower cost?“Instead of having a separate isolated battery charger, we introduced a new concept for the power transfer, the rotating transformer, which was developed to transfer electric power while rotating,” says Saeid Haghbin. “The battery is charged through the transformer and a split-phase electric motor that was especially designed for this purpose.”
