Abstract

Today, batteries are widely used in mobile devices, vehicles and military applications. Batteries meet the energy needs of the equipment on the vehicle in military vehicles which is one of the application areas. During the military vehicle is stationary, the vehicle engine must not work for camouflage. Therefore, it needs a battery charge circuit. Controlled charging/discharging of the batteries is very important for the cycle life and safety of the batteries. Many conventional battery chargers units charge it without considering the battery temperature. In this study, adaptive battery charging method design and circuit is taken into consideration, considering the battery temperature. The adaptive battery charging algorithm has been applied to charge the batteries of military vehicles and in accordance with military standards (MIL-STD-1275-E voltage surges and MIL-HDBK-454B electronic equipment standard). In this study, experiments with different charge rates have been made and conventional constant current and constant voltage method and proposed adaptive battery charging method result are compared. Experimental results show that the battery temperature decreases 15 degrees C with the proposed charging method. This adaptive battery charging method has been shown to prevent overheating of the battery.
