For such applications, you should use a regulated power supply like our 1446 or 2304. What Is Regulated Power Supply? A regulated power supply has all the same parts that unregulated supplies do but with the addition of a voltage regulator. This part ensures the output delivered is smooth and unchanging, regardless of draw or input.
What Is Overcurrent? (Causes, Effects, and Protection)
Another example is if a current of 167A passes through a cable with a current ampacity of 135A, this cable is over the current situation.. In general, any electrical equipment has a rated current, whenever the current exceeds this value, it''s an overcurrent situation.
Using a Switching Power Supply for Battery Charging
In Figure 1, these are the three-main power supply overcurrent protection characteristics. The most appropriate method for charging batteries among them is with a power supply that has constant current voltage drooping type characteristics (Far Left) where a constant current range is used for charging batteries with a constant current.
The "midstream" portion of the EV battery supply chain has the power to improve supply chain traceability, a practice in which products are tracked from their source to the consumer. Since ...

1 cell overcurrent charging problem | DIY Solar Power Forum
Hi, It''s my first post, just build a first battery in my life. BMS did not blow up, app connection is successful, cells 3,33-3,34V. PROBLEM: when i pluged a charger to battery, cells have different voltage during charging. When I crank up the power supply, to 14v 2A, they are disconnecting due to 1 overcurrent cell protection (3,6V) Video here:

The DCDC-8A can easily be used with 12V and 24V vehicle installations for charging your 12V LFP batteries. The unit can also be powered by a desk top Power Supply such as the SS-30DV. It is not suggested that you power the charger direct from a solar panel and/or solar charge controller due to the variable power output. Installation:
The BMS, even if it has overcurrent and overvoltage protection, is only the last line of protection if the charger has failed to prevent further damage. Do not connect a power supply directly to the BMS or batteries. The batteries or the power supply may be damaged, and damaged batteries are dangerous. You need a charger which can …
I''m making a power-supply circuit for some MCUs using a battery charging-discharging protect module MH-CD42 (both input and output is 5 V). The module''s datasheet says it has a 0.3 seconds switch time when connecting or disconnecting the DC power input, so I use a 10 F super capacitor to make sure those MCUs don''t power off …
