Abstract	A Spanish SME has developed an innovative fast battery charger for the automotive and transport sector that reduces the charging time to one third when compared to a conventional charger. This charger produces a current intensity much flatter and less curled than the conventional ones, so the charging process is very efficient without excessive heat production and without durability reduction. The company is looking for partners to establish a license agreement.
Details	The charging process with the new battery provides a high yield, being carried out at a high speed. Depending on its power, the charger brings the highest intensity, which is around one third of the battery ´s capacity, according to the battery ´s temperature. This charger uses all the voltage as charging voltage, so controlling the voltage in the battery terminals prevents overload. The main characteristic of the charger is that it reduces the charging time to one third in comparison to a conventional one, what means that the waiting time is significantly reduced. This fast charger charges in three hours a battery, which would require nine hours with a conventional charger, including the charge of equalization of the vessels of the battery. Besides reducing the charging time, the device produces a flatter and less curled current intensity than the usual chargers, what involves a longer working life. Considering the above-explained characteristics of the charger it can be deducted that the charging process takes place in a very efficient way without producing excessive heat in the battery, which could reduce its durability. The battery charger can be adapted for all battery types and depending on this its technical characteristics such as input voltage, frequency, dimension, weight, etc, may vary. Several essays were carried out in order to compare the new charger with a conventional one. Two identical batteries were connected to both chargers giving the following results: - The charging time using the new charger is 3.5 hours while using the conventional one takes 7.2 hours. - Both batteries remain in good conditions and the ageing is similar for both after a number of cycles. The new charger presents a lower content of harmonics for all the currents, even at maximum intensity. The harmonic distortion rate is 9.26 % for the new charger and 29.8 % for the reference one. Both chargers have similar yield. Further, this charger has an information storage system, which allows registering the charge operations for each battery, being later indentified through a code of bars reader. To provide added value, there is also a system to manage the information and the interaction between the worker and charger. The information deals with the way of charging, the date of the last charging, percentage of the charge used, number of charging, etc. In this way a predictive maintenance of the batteries can be carried out. Innovative Aspects: The innovation deals with the reduction to one-third the normal charging time. Regarding the main advantages, the time of charge is reduced, the charger can be used for any battery or energy accumulator and the battery’s working life is increased.
