The utility model discloses a precharge circuit of a power battery, which comprises an optical coupler for isolating high voltage, an MOS tube with N channels, a high power precharge resistor, a first divider resistor, a second divider resistor, a zener diode, and a voltage stabilizing ...
Precharge: When the system is first turned on, K1 and K3 are turned on to precharge the load, until the inrush current has subsided. R1 shows the location of the thermistor in the precharge circuit. ON: After precharge, contactor K2 is turned on (relay K1, must be off to save coi...
Precharge Circuit Inrush Current I(0) I(t) = \frac{V_b}{R_1}e^ \frac{-t}{R_1C} Evaluated at t=0 I(0) = \frac{V_b}{R_1} Peak current at t=0, right when the precharge contactor is closed. This is important for checking the capability of the precharge contactor to clo...
The battery cells are not rated for the inrush current Function The precharge circuit consists at the minimum of: A precharge resistor, to limit the inrush current (R1) A contactor (high power relay) across the precharge resistor (K2) to bypass the resistor during normal operation ...
