Customer ServiceIn 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].
At higher constant charging current rates the battery charges more effectively and this does not only apply to the Vanbo Battery (battery Sample 01) that was tested before but it was also true for the Winbright battery (battery sample 02) tested too.
Discussions The charging and discharging of lead acid batteries permits the storing and removal of energy from the device, the way this energy is stored or removed plays a vital part in the efficiency of the process in connection with the age of the device.
Therefore, a tradeoff magnitude of charging current and health of battery will have to be found by future charge controller designers in order to safely increase charging current while protecting the battery from thermal run away. The paper also shows that the age of the battery plays a vital role in charge/discharge characteristics of batteries.
The curve demonstrates only about the charging phases of the battery at the three different constant current regimes tested. It is noticed that the higher the current regime, the greater the temperature rise. For the 0.5A current, the temperature barely attains 27 °C after a whopping 989 min time of charge.
Particularly, fast charging at low temperatures can cause lithium to deposit on the anode of the battery, intensifying heat production and even evolving into thermal runaway of the battery. Based on the simplified battery Alternating current (AC) impedance model, the optimal frequency of pulse current is analyzed.
