Patco Electronics was established in the autumn of 1992 with the mission of providing the electronics industry with cutting-edge battery management tools that cover the chemical technologies used in secondary batteries. The company's first product was a lead-acid battery manager designed based on the Unitrode 3906 lead-acid controller. Since then, Patco has expanded its lead-acid battery product line to include higher-current managers for larger batteries and developed algorithms tailored for uniquely structured lead-acid batteries. Subsequently, the company introduced NiCAD and NiMH battery managers built around specialized controllers. A third product line focuses on medium-sized prismatic lithium-ion batteries produced by Saft America.
