6 FAQs about Inverters & Power System Solutions

Do EV batteries need to be monitored correctly?

As EV battery systems continue to shift toward higher voltages, ensuring safe and efficient measurement becomes increasingly important. This article outlines the key considerations for accurately monitoring voltage and temperature in high-voltage battery packs, helping to support safer and more efficient EV development.

How do you test a battery pack?

This testing can be a bottleneck in the manufacturing process, so test solutions that reduce time or increase test density are highly desirable. One of the most useful measurements for a battery cell or pack is the open circuit voltage (OCV), but the considerations that must be made at the module or pack level differ from the cell level.

Can I disable a battery pack if the cell voltage is accurate?

You must account for the accuracy of the cell voltage measurement when determining whether to disable the battery pack.

How do you charge a battery with a buck converter?

To charge the battery, the buck converter is enabled while the first-stage voltage Op Amps and current-sense INA are used to measure battery voltage and charging current of the battery cell or battery pack.

Why is 50 mV of battery capacity unavailable?

50 mV of usable battery capacity is unavailable due to the inaccuracy of the measurement. Clearly, the more accurate the voltage measurement of the cell voltages, the less cell capacity wasted. ±5 mV at 2 V to ~5 V at 25°C. ±10 mV at 2 V to ~5 V, across 0°C to +60°C.

What unit is a cell voltage measured in?

Cell voltage measurements are reported in units of millivolts, while voltages measured for the stack, PACK pin and LD pin are reported in units of centivolts (10 mV) or millivolts, as set in Settings > Configuration > DA Configuration in device data memory. Raw ADC readings are provided in units of counts.
