Recently, I came into contact with the matching test of BMS high-voltage distribution box and vehicle functions. Although there were problems of one kind or another, it was also a gain for me. Combined with network resources, I made a little arrangement.

Main circuit topology
The load of the high-voltage system mainly includes motor controller, electric accessories, etc., especially the motor controller has a large bus capacitor C. When the cold state starts, the capacitor C has no charge or the residual charge is small.
If there is no pre-charge circuit, the main positive and negative relays are directly closed with capacitor c, BP_V is high voltage, 300 volts, the voltage across c is close to 0V, which is equivalent to instantaneous short circuit, and the load resistance is only the resistance of conductor and relay contact. According to Ohm's law, BP_ I = BP_V/R , R value is mΩ level at this time, BP_ I will far exceed the relay capacity, assuming wire and relay contact resistance is 30mΩ,BP_V = 300V, then BP_ I = 300/0.03 = 10000A, and the main positive and negative relays are easily damaged.
Pre-charge circuit
Add a pre-charge relay and a pre-charge resistor Rs(Rs is 100 Ω). During power-on, BMS first controls the main negative relay and pre-charge relay to close, and the main positive relay is disconnected. At the moment of connection, the current Ip = 300/100 = 3A flowing into the capacitor C through Rs, and the loop is safe within the capacity range of the pre-charge relay and the main negative relay;
After the capacitor C is charged to meet the target requirements, a relatively high voltage (close to the battery voltage) exists at both ends of the capacitor at this time, and the pressure difference between both ends of the relay is also relatively low. At this time, there is no large current impact when combined. BMS controls the pre-charge relay to disconnect, and combines the main positive relay to connect the high voltage.
Some motor controller manufacturers have a buffer unit, namely a buffer resistor, inside the controller, which is the same principle as the above-mentioned pre-charging relay circuit, that is, a buffer (pre-charging) resistor is connected first at the moment of power-on, and when the load capacitor is charged to the target demand, the buffer (pre-charging) resistor is disconnected and the main positive circuit is connected.
Pre-charge time
Pre-charging time is a relatively important parameter. In the test, due to the small resistance value of the pre-charging resistor provided by the manufacturer (less than 100 Ω), the collected data show that there is no obvious pre-charging process. At the moment of power-on, it will have a certain impact on the relay in the high-voltage power distribution unit.
Our company provides pre-charging resistance and charging time calculation software for customers to choose. Welcome to QQ:67277123
Pre-charge time calculation
Let V0 be the initial voltage value on the capacitor.
V1 is the final voltage value that the capacitor can be charged or put;
Vt is the voltage value on the capacitor at time t.
Then pre-charge time:
T = RC * ln [(v1-v0)/(v1-dish)]
For example, if the capacitor with an initial value of 0 is charged through Rs and the charging termination value is Vcc, how long does it take to charge to 2/3 Vcc?
T = RC * ln [(v1-v0)/(v1-dish)]
= RC * Ln[(Vcc-0)/(Vc-2/3Vcc)]
=RC*Ln3
SINOCHIP PTC thermistors have some key advantages as ICL components for active inrush current limiting in a number of applications:
-Its ICL function will not be affected by extreme operating temperatures.
-Once the load is turned off, effective inrush current limiting can be achieved, and cooling is already carried out during normal operation.
-Self-protection against current overload caused by circuit fault.
Thanks to the broad product portfolio of SINOCHIP ICL, you can reliably protect your power supply from high inrush currents and short circuits under harsh temperature conditions.
Charging control circuit of energy storage capacitor
Self-protective charging resistors are based on PTC (positive temperature coefficient) ceramics and are used to smooth capacitors in power supplies. When a short circuit occurs, they limit the current to a safe level.
Ordinary resistors are often used to limit current when charging capacitors. However, there are technical risks. For example, when shorting a capacitor, the resistor will continue to be exposed to high power levels if the capacitor is shorted or the relay fails. This may cause the resistor or the entire system to be destroyed. Huagu Electronics uses the new MZFLY series charging resistor based on PTC ceramics, and has now developed a professional solution: while protecting itself, it also achieves a relatively compact size.

l Typical application circuit:
Ⅱ Selection
Select the charging capacitor according to the following formula
C: filter capacitor. 0.7: safety factor
Tc: Curie temperature of PTC Ta: Ambient temperature
V: Capacitor charging voltage (V = 1.414xVs)
ENon60=0.7x(Tc-Ta)xCth ENon60=0.7xth
ENon60: maximum inaction energy @ 60 ℃(Ta = 60)
