Portable Battery Charger For Electric Vehicles Pdf Battery Charger Transformer I have just installed two brand new 12v lead acid batteries in series to for my 24v “house system” on my boat. i connected them to my 24v charger to ensure they were charged to 100%, to synchronise. I use a laboratory power supply to confirm this. it seems batteries "prefer" being charged slowly since it gives time for the chemistry to work its "magic". i haven't had any issues (it seems) with this slow charging method and the good part is if there is a power interruption, unlike smart chargers, my method recovers nicely. \$\endgroup\$ –.
Electric Vehicle And Power Electronics Pdf Electric Motor Battery Charger For negotiating the power, usb c has an passive and an active standard. passive method. with the passive standard, you use your microcontrollers adc to read the voltage on both cc pins, and take the highest voltage (make sure to properly deal when vbus is not yet active, so use a 22k resistor to prevent the microcontrollers esd diodes from affecting the connection test from the charger). Coupled with higher voltage, that gives a lot higher charging power. all in all, i guess that the laptops will as well charge with 5v (on usb a charger), just far slower. and based on what i saw from apple for their new macbook, the charger is 29w, so most likely a profile 3 (a bit under spec), it seems then to be only 12v. The battery voltage as nominal 13.5v is measured while in the charging process. if you measure without charging, a “skin” effect in the electrode plates might give you an abnormally high reading just few minutes from being charged. if you wish to remove the skin effect of charging, turn on a load as car light beams for 5 minutes or so. That is why you use a balancer while charging a pack of cells in series. it balances the cells to an identical voltage level by discharging the higher voltage cells. there's nearly no memory effect. no need to discharge before charging. for long term storage charge it to 65 80%. not less to avoid undercutting the minimum voltage.

Yes. in short, smart ports use hacks of non standardized charging mechanisms to achieve optimal currents. the common assumption that all usb devices base their charging protocols solely on the usb spec or the bcs extension is false. many usb chargers only have 'dumb' floating data pin ports described by the bcs, aka dcps, dedicated charging ports. Most lithium charger ics measure each cell's voltage when charging begins and if the voltage is below a minimum of 2.5v to 3.0v it attempts a charge at a very low current . if the voltage does not rise then the charger ic stops charging and alerts an alarm. \$\endgroup\$ –. In practice charging li ion safely and efficiently does involve quite a few steps so you may want to look at a dedicated charger chip. you'd need to check the datasheets for any that look of interest but many will operate properly with a supply voltage only a little above 4.2v. Solution 2: change the charger to 24v instead, than you need to check how much current does the charger provide versus how much the system consumes (batteries charging the electromagnectic) to see if the charger can support while the system is on.
