Abstract
This article addresses some practical issues of the Japan Electronics and Information Technology Industries Association (JEITA) battery charging guidelines and common industrial practices. The issues involve the temperature-dependent charging profile that may not lead to optimal charging time. A hybrid temperature-regulated current control (HTRCC) is proposed and compared with common JEITA charging profile in order to minimize the charging time within the thermal limits of the battery. The form factor of the charging current is used for a quick verification that HTRCC can shorten the charging time. Based on an electro-thermal battery model, the minimum charging speed improvement rate compared to JEITA charging profile is also predicted. Practical measurements of the charging profile and charging time are included to confirm the theoretical analysis.
