If a battery is connected to a significant load during dun, the end of the Uo-phase may never be reached and the battery will gas and be damaged, depending on the charge current relative to the battery capacity. During this phase, the charge current decreases gradually to a small residual value that compensates for any self-discharge of the battery. It consists of three phases or stagesto be executed by a battery charger. The voltage in the U o -phase is too high to be applied indefinitely hence, overvoltagebut it allows charging the battery fully in a relatively short time. IUoU battery charging The charging current is a compromise between charging time favoring high currentsthe prevention of damage due to overheating or gassing favoring low currentsand cost of the charger favoring low currents.

Samur The charging current is a compromise between charging time favoring high currentsthe prevention of damage due to overheating or gassing favoring low currentsand cost of the charger favoring low currents. The charger provides a constant current, typically the maximum current that the charger is capable of producing. Stage 3 is called the U-phase or float charge statethe voltage is reduced to a value that is safe to be applied for long periods weeks without significantly reducing the lifetime of the battery.

Batteries have varying numbers of cells typically six for an battery and may be flooded-cell, absorbed-glass-matt AGMor gel-electrolyte types. The current in the I-phase stage 1 should be chosen depending on the capacity of the battery.

In this stage, the battery is continued being charged at a constant over voltage U obut the charge current is decreasing. For the alternating-current system, see Three-phase electric power. In practice, it depends on the capability of the charger. It consists of three phases or stagesto be executed by a battery charger. The decrease is imposed by the battery. The charger limits the maximum voltage to U maxa constant or temperature-dependent maximum, typically around 2.

From Wikipedia, the free encyclopedia. The purpose is to fully charge the battery in a relatively short time without reducing its life span and to indefinitely keep the battery charged as long as the charger is connected.

If diin battery is connected to a significant load during charging, the end of the Uo-phase may never be reached and the battery will gas and be damaged, depending on the charge current relative to the battery capacity.

Stage 2 is called the U o -phaseconstant-voltage boost stageabsorption stageor topping charge. The voltage in the U o -phase is too high to be applied indefinitely hence, overvoltagebut it allows charging the battery fully in a relatively short time. An issue of continuity The three phases are: The voltages in the U and U o phases stages 2 and 3 depend on the type of battery and the temperature.

Views Read Edit View history. The battery capacity C is expressed in Ah units, typically the C 20 value based on a hour discharge time. The U o -phase is concluded when the charge current goes below a threshold I minafter which the U-phase is entered.

A bad battery will have short I-phase and Uo-phase, but there is a risk of gassingfurther damaging the battery. Stage 1 is called the I-phaseconstant-current stageor bulk charge stage.

Stages[ edit ] Stage 1 is called the I-phase, constant-current stage, or bulk charge stage. This phase occurs when an IUoU charger is connected to a deeply discharged battery. The charger provides a constant current, typically the maximum current that the charger is capable of producing. As a result of the current, the battery absorbs the charge and its voltage rises. The charger limits the maximum voltage to Umax, a constant or temperature-dependent maximum, typically around 2.
