A CMOS fully-integrated Coulomb counter based on a voltage-to-frequency conversion algorithm that measures the state-of-charge (SoC) of a high-density Li-ion battery is presented. Low-side current sensing with a polarity detector is used to monitor the charging and discharging battery current. It is designed in 0.35 μm CMOS process and occupies an active area of 0.01mm2. Except for the sensing resistor...
Implementation of precision apiculture methods into practice is highly depended on availability and cost-effectiveness of honey bee monitoring equipment.

Most of the Wireless sensors today are powered using lithium batteries. The need to detect the end of life for these batteries has increased in the recent past due to a large manufacturing variation between suppliers and storing practices. It has become a challenge to explore the ways to access the health of these batteries in field due to the difficulty in measuring the internal state variables of...
Today, supercapacitor usage as high durability battery is feasible. The storage capacity in milliamperes-hour is one of the main parameters of a battery, used to determine the running time of an energy independent system. While powering some simple circuits, a shorter up-time was obtained, when the capacitor was charged at high current. Further analysis with an advanced charger showed that the charging...
Due to their high storage capacity, low self-discharge rate and long lifetime Lithium-Ion batteries are key elements for the emerging electro-mobility and for stationary “Battery Electrical Storage Systems” (BESS). However, Li-Ion batteries are still very expensive and must be handled very carefully to exploit their features optimally. Hence, “Battery Management Systems” (BMS) have been developed...
Lithium ion batteries are promising for small off-grid energy storage applications in developing countries because of their high energy density and long life. However, costs are prohibitive. Instead, we consider “used” Li-ion batteries for this application, finding experimentally that many discarded laptop cells, for example, still have good capacity and cycle life. In order to make safe and optimal...
Large lithium-ion battery systems rely on battery monitoring and management systems to ensure safe and efficient operation. Typically the battery current, the cell voltages, and the cell temperatures are monitored. This paper describes the use of gas sensors in large lithium-ion battery systems in addition to conventionally used means of battery monitoring. An undetected electrolyte leak in a cell...
