Traditionally, the charging of batteries is being performed at varying current rates but this charging method presents a drawback in the sense that adequate estimation of the energy input and energy output cannot be easily obtained. Also, the present charging techniques still present lower efficiencies.
The authors concluded that the higher the magnitude of charging current in lead acid batteries, the higher will be the efficiency of the charging process. The authors conducted the experiments on Vanbo DG121000 12 V 100 Ah battery (20 h) .
The test results demonstrate that high-power charging significantly impacts the durability and thermal safety of the high-capacity lithium batteries. In particular, the capacity fading rate can reach up to 30% only after 100 charge cycles depending on the battery type.
Further, the migration characteristics of the temperature threshold of battery thermal runaway are investigated using the proposed procedure. The test results demonstrate that high-power charging significantly impacts the durability and thermal safety of the high-capacity lithium batteries.
However, the primary factor that significantly affects the charging time, charge/discharge capacity, temperature rise, charging efficiency, and lifetime is the charging profile. The charging time is shortened as the charging current rises above a particular level, but at the same time, the charging efficiency and lifetime deteriorate.
In this paper, the impact of high constant charging current rates on the charge/discharge efficiency in lead acid batteries was investigated upon, extending the range of the current regimes tested from the range [0.5A, 5A] to the range [1A, 8A].

Although one can envision the prosperity and development of EVs in the near future, some hurdles are critical to overcome. Most current EVs have limited mileage (200–300 miles) and require relatively long charging time (one to two hours for fast charging), while fossil fuels-powered vehicles show longer mileage (300–400 miles) with a much shorter refueling …

Higher charging current, within the manufacturer''s specified limit, in the low SOC level has a less detrimental impact on LIB life cycles and performance parameters [71]. When the SOC exceeds a particular threshold (usually it is 40%–50% of SOC), a higher charging current has a negative impact owing to polarization.
