<p>The present application provides systems and methods for battery temperature detection and parasitic resistance compensation. Compensation circuitry is provided to generate a compensation current, proportional to a battery charging or discharging current, to compensate for the parasitic resistance associated with the line connection between a charger/monitor and a battery pack. The compensation current operates to adjust a reference current supplied to a temperature sensor, to enable accurate temperature measurement of the battery pack while reducing or eliminating influence from the parasitic resistance. The compensation circuitry can be utilized in a battery charger topology to enhance battery charging control and/or a battery monitoring topology to enhance battery discharge control.</p> |
