Abstract
In an arrangement for charging a battery in a battery plant, a resistive network is situated in the charging path of a battery being charged to guarantee a minimum total resistance of the added resistance and the battery's internal resistance regardless of the thermal effect of reducing the battery's internal resistance. A diode path bypasses the resistive network during discharging of the battery to reduce power dissipation. Charging current is controlled in response to a temperature of a heat sink on which the resistive network is mounted. Ambient temperature is used as a control or in another arrangement as a controlling factor in controlling charging current. Battery temperature may also be used as a control or in another arrangement as a controlling factor in controlling charging current.
