Current limiting using a Quattro

I have a Victron Quattro with a Venus GX. We have solar panels and mains input (from a hydro-electric system). The amount of electricity from the hydro fluctuates and at the moment is very low as it is so dry.

How to limit current when charging from alternator

The battery is directly connected in series with the alternator via a Victron Schottky diode battery isolator that drops the more or less constant 14.5V output to a maximum of v14.1V at the battery terminals. The initial charge current starts at c90A and slowly lowers over about 30 minutes to nearer 75A as the presumably temperature controlled

4.6: Current Limiting

Consequently, we must include some method to limit the current to a safe maximum value. While some electronic systems use active current limiting schemes 1, the more common approach is a fuse or circuit breaker. These devices are placed between the voltage source and the various loads, and see their combined current. If this current becomes too

DC-DC charger current limiting

I normally see a maximum of 8-9 amps with a low battery and rather soon it settles down to only 1-2 amps, depending on my alternators current output. This of course is safe for the wiring. I suspect a similar current limiting effect will occur with the lithium battery but I haven''t had a chance to test it.

Current limiting circuit: The simplest and a robust solution is to use headlight lamps as power resistors. A more elegant option is to use sensing resistors (0.6~0.7V of voltage drop at max. current) monitored by a driver transistor to control a series-pass power transistor, heatsinked.This is essentially a current limit, but causes a minimum

6 FAQs about [Battery current limiting version]

Can input current limit extend battery life?

Using Input Current Limiting to Extend Battery Life Despite constant advances in battery technology, producing a battery still involves multiple tradeoffs between different design goals such as size, self- discharge, or capacity to name a few.

What is the input current limit?

The input current limit is active during normal operation as well as during startup. This effectively limits the inrush current, and can also be used to reliably charge heavy loads, such as a supercapacitor, from a weak battery. The converter has eight current limit settings going down to 1 mA, as listed in Table 1.

How is the current limit estimate determined?

What is the maximum voltage a lithium battery can charge?

There was an immediate voltage change when the high rate pulses were applied. The maximum current that could be applied to the cathodes, at the rated charging voltage limit for the cells, was around 10 C. For the anodes, the limit was 3–5 C, before the voltage went negative of the lithium metal counter electrode.

What is a brick wall current limit?

In a brick-wall current limit, the upper boundary is defined and the LDO supplies current incrementally until the limit current limit is reached. Once the current limit is exceeded, the output voltage is not regulated and is determined by the resistance for the load circuitry (RLOAD) and the output current limit (ILIMIT) (Figure 2 Figure 2. (1)

Can a battery pack be protected if a vehicle controller knows power limits?

These voltage limits will have to be applied anyway, but they tend to be a hard stop. If the vehicle controller knows the current/power limits ahead of time then the battery pack can be protected and the user can be limited more gradually to avoid the sudden loss of power.
