How can I control the current that is supplied to a battery? I need to balance current consumption to avoid some parts of the system run out of power. My system is described in the attached file. I have a 12V input which goes into a Boost regulator to get 48V. Those 48V
Current-Mode Control For current-mode control there are three things to consider: 1. Current-mode operation. An ideal current-mode converter is only dependent on the dc or average inductor current. The inner current loop turns the inductor into a voltage-controlled current source, effectively removing the inductor from the outer voltage

The datasheet of my 18650 cell says I can charge it at 1.7A max. So I need a way to limit the INPUT current to 1.7A today, but 10.2A later (6*1.7A, because of 1s6p). How can I do this? For now, I am using my bench PSU to charge the battery pack, where I set it at 4.2V output and current controlled at 1.5A max. This is not very convenient.

To obtain a charging current of 100mA, a resistor (R) of twelve ohms may be used, whereas for a current of one amp, a 1.2 ohm 2-watt resistor is required. A diode can be added in series with the input to prevent any reverse voltage from the battery packs to the regulator IC when power is turned off, and the batteries remain connected.
This paper proposes a battery charger (BC) for electric vehicles based on sinusoidal-ripple-current (SRC) method. The SRC method is used as an advanced charging-discharging method. On the one hand, the sinusoidal current variations alternately change output active power of the BC, negatively affect AC-side terminal current of the BC, and therefore, cause a power quality

I have a DC boost that converts the 2.5V/4.2V of my battery pack to constant 5V output (and can output up to 3A, which is nice). Here is my problem : my BMS does not limit INPUT current. I choosed this BMS specifically because it has big OUTPUT current (about 15A). The datasheet of my 18650 cell says I can charge it at 1.7A max.
I am wanting to connect it to a constant 12v car battery but because the current draw is 160 mA, it is too high and risk draining the battery too quickly. So my question is, is there a way to control the current draw until I use the remote to activate the switch? It is currently wired up to actuators and I need some constant power to keep

This is why, even is a fairly low value circuit breaker is fitted in the battery, motor current can still be very high, and why all controllers manufactured by 4QD have motor current limiting, to protect the MOSFETs. If you have found this article useful please share it to help others discover it
The controller varies the motor speed by varying the voltage fed to the motor. The motor draws whatever current is demanded of it by the mechanical loading. You can use our motor current calculator to work out how mechanical load affects motor current.
The motor controller serves as the brain of the powertrain system. It receives commands from various inputs, including the throttle, brake, and forward/reverse switches via CAN Bus. Based on these inputs, it adjusts the energy flow between the motor and battery, controlling the vehicle's speed and torque output in real-time.
PWM controllers are not far short of 100% efficient – they cannot dissipate a huge amount of heat – so very little of the power drawn from the battery is lost in the controller. The controller varies the motor speed by varying the voltage fed to the motor. The motor draws whatever current is demanded of it by the mechanical loading.
