| Abstract |
Most of the battery charger for electric powered forklift truck are controlled by the method of 3-phased constant current and constant voltage controls. However, these chargers have several disadvantages like a large charger capacity, and a short battery life time. To eliminate the weak points, a digital type battery charger based on multi-mode control adding a constant power control and several assistant controls in the conventional control is presented. The whole control system is performed by a low cost 8 bits one-chip micro-controller and completely digitize. So, we can get a high precision control and a good reliability. |
