Actual battery capacity reflects the performance of a battery under specific conditions. It can be calculated using the following formula: Actual Capacity Ah =Discharge Current A ×Discharge Time h Actual Capacity Ah = Discharge Current A × Discharge Time h For example, if a battery discharges at 5A for 10 hours, the actual capacity would be: Actual …
The initial state of charge (SOC) is equal to 0.3. When the battery is charging, the current is constant until the battery reaches the maximum voltage and the current decreases to 0. When the battery is discharging, the model uses a constant current. This plot shows the current, voltage, and temperature of the battery under test.
Voltage measurements of the battery stack are also affected by PCB layout and connection drops. Some battery-pack designs may use nickel straps from the PCB connection to the battery stack. Nickel is used because it is easy to weld to the battery cells, but its resistance is five times as much as that of copper.
The electrical path to pull up the battery pack VCC passes through the host capacitance from Pack+ to Pack–, through a substrate diode in the host interface driver from VSS to the commu-nication or interface line, and through a substrate diode from this line to VCC in the battery-pack circuitry. The complete path is shown in Fig. 6.
The gas-gauge circuitry measures the charge and discharge current by measuring the voltage across a low-value sense resistor with low-offset measurement circuitry. The current measurement is integrated to deter-mine the change in coulometric capacity.
The equipment must generally withstand both positive and negative discharges of at least 15 kV to all connector pins as well as to the case of the battery pack. Most require-ments go further than just requiring survival, insisting that there be no observable disruption in performance.
Battery-circuit design and layout are consid-erably more critical than might be expected.
