Regarding with/without Battery Life, in my opinion Battery Life is best suited for Lead-Acid batteries, which must be fully recharged as soon as possible. Keeping lead-acid batteries partially discharged for a long time will damage them. For LiFePO4 there is no damage if they are not fully charged even for weeks, if not months.

A reliable and safe energy storage system utilizing lithium-ion batteries relies on the early prediction of remaining useful life (RUL). Despite this, accurate capacity prediction can be challenging if little historical capacity data is available due to the capacity regeneration and the complexity of capacity degradation over
Accurate estimation of the state-of-energy (SOE) in lithium-ion batteries is critical for optimal energy management and energy optimization in electric vehicles. However, the conventional recursive least squares (RLS) algorithm struggle to track changes in battery model parameters under dynamic conditions. To address this, a multi-timescale estimator is

All cells have an operating voltage window that charging and discharging should occur to ensure proper operation and battery life. If an application is using a battery with a lithium chemistry, the operating voltage typically ranges between 2.5V and 4.2V. The voltage range is chemistry dependent. Operating the battery outside the voltage range
This prediction model uses historical capacity sequences as input and residual useful life as output. The data size of historical cycles is critical for the early prediction model. According to most existing studies, the starting point for predicting battery life is generally 50%-70% of the total cycles since the battery was first charged.
Generally, battery aging models are developed to simulate the decay of battery life and to access the internal relationship between the input sequence and life cycles to accurately determine the life remaining of the battery. In the existing studies, the prediction approaches of RUL are divided into two types: model-based and data-driven .
This is not a good way to predict the life expectancy of EV batteries, especially for people who own EVs for everyday commuting, according to the study published Dec. 9 in Nature Energy. While battery prices have plummeted about 90% over the past 15 years, batteries still account for almost a third of the price of a new EV.
To promote the use of NEVs, multiple values of battery recycling in terms of economic benefits and environmental protection are considered. Establishing a management system for the full life cycle of NEV batteries should be promoted. Fig. 9. Bubble chart showing annual trends for the top 20 journals in publications. 3.5.
Positive and effective incentive policies can promote the recycling of NEV batteries . The government should encourage relevant enterprises in the market to establish a comprehensive recycling system while attracting consumers to actively participate in battery recycling.
