“…Researchers [25][26][27] have studied battery degradation under different operating conditions, such as the ambient temperature, state of charge (SoC) range, charge/discharge rate, and cut-off voltage, through which battery life can be extended. In work [28], researchers reported that to delay battery degradation, the charging process can be significantly affected by adjusting the charging current and cut-off voltage. In work [29], researchers studied the aging behavior of batteries during long-term cycling at high charging rates to explain the aging effects of batteries.…”

The impact of different charging currents and surrounding temperatures has always been an important aspect of battery lifetime for various electric vehicles and energy storage equipment. This paper proposes a bidirectional long short-term memory model to quantify these impacts on the aging of gel batteries and calculate their state of health. The training data set of the bidirectional long short-term memory model is collected by charging and discharging the gel battery for 300 cycles in a temperature-controlled box and an automated charge and discharge device under different operating conditions. The testing set is generated by a small energy storage device equipped with small solar panels. Data for 220 cycles at different temperatures and charging currents were collected during the experiment. The results show that the mean absolute error (MAE) and root-mean-square error (RMSE) between the training set and testing set are 0.0133 and 0.0251, respectively. In addition to the proposed model providing high accuracy, the gel battery proved to be stable and long-lasting, which makes the gel battery an ideal energy storage solution for renewable energy.

This paper presents a novel thermal protection circuit for low dropout regulators (LDOs). To avoid thermal damage under high power conditions, the output current of LDOs varies with the sensed load temperature. Both the current delivery capability at a pre-set temperature and the limit slope of load current can be tuned to accommodate different load conditions and temperatures. The proposed design was fabricated with a 0.18 µm CMOS process with a chip area of 0.073 mm2. Chip measurement results show that the proposed design reduces charging time by 18% over the conventional thermal shutdown structure.
