Pre-Charge Resistor
When the battery pack contactors are closed onto a motor and inverter there will be an inrush of current into the inverter capacitor. This very high current is at a minimum likely to age the contactors, it could permanently damage the contactors. Therefore, when we closed the contactors on the battery pack we do this in three steps:
Battery SOC: How Do We Estimate "State Of Charge" Of Batteries?
Determining State Of Charge By Measuring The Voltage. A battery''s SOC is often measured by its voltage, as the process is simple and yields fairly accurate results. It basically converts a reading of the battery voltage to SOC and displays it to the user. Let''s try to understand this process with the help of an analogy.
