Just remember that the faster you charge, the more heat is generated. Heat is one of the biggest causes of a cell degrading. You will get longer life/more charge cycles using slower charging.

@tedforester133 2 жыл бұрын

I looked for this comment before posting the same thing. I see people kill their cell phone batteries using "fast charge" for every time they plug in. Fast charging shouldn't be everyday charging, and shouldn't be more than 80% of the max battery capacity.

@petergilbert72 2 жыл бұрын

Am I right in thinking that least ‘friction’ among positive and negative ions occurs when you charge a half full battery eg charging it from 40% to 60%? And that this is the optimum for battery health and long life?

@devildogcody 2 жыл бұрын

@@petergilbert72 Not sure about friction, but the chemical process of discharging a lithium battery is exothermic (generates heat), and for charging is endothermic (absorbs heat). Most battery chargers are designed to operate with the batteries specific "C" rating in mind and to not max that rating out. You can technically charge at the max C rating of that battery, but the outcome will be shorter life. Charging above that rating can possibly cause venting and thermal runaway (a violent and rapid exothermic reaction). Luckily thermal runaway is fairly rare as the individual cells have built in protections that disable the battery, effectively killing it but avoiding further damage....think about how often you see stories on "exploding batteries"....then think about just how many lithium batteries you yourself actually have......almost all modern electrical devices with built in batteries are using a form of lithium cell. I have 5 just within arms reach of where I am sitting right now. The ultimate goal is to find a charge rate that is fast enough for you to be useful, but low enough to minimize cell degradation in your battery (the science behind the degradation goes a little deep for me, all I needed to know was that heat speeds up the process, and extreme cold can as well...though a different type of degrading). I think for most battery packs you can purchase, 5A charging is a fairly safe range...and up to 10A when high quality, high C rating cells are used. Those super fast, "charge up in under an hour" chargers may technically be "safe" as in not exceeding the battery packs C rating, but you are going to end up with 100-300 charge cycles instead of the 500-800 you could get using a slower charge method.

I love all your informative videos. Is it safe to use a smart plug to set up a charging schedule for your e-bike battery? That way it's not sitting at or near fully charged overnight adding strain to the battery, in a sense it makes for faster charging since you don't have to keep an eye on it or plug it in early in the morning. Also, isn't one of the reasons it takes so long to get the last few percent is your charger is balancing your cells, which is not necessary to do all the time but is good to do periodically, correct?

@miespost 2 жыл бұрын

Smart plugs are great just have the charger on when you plug it into the battery so it doesn’t spark at the battery connector, I used to use a Christmas light timer before I got a Luna advanced charger that I highly recommend because using a smart plug/ timer is kinda anoying rather then just plug in and charge at 1 amp to 80%. The last 15% charge slow because the cells have to be constant voltage charged to full cell voltage. Balancing occurs at this point because it is when cells that are charged above the rest will reach full charge first and the bms can burn off with resistors or use capacitors to redistribute the excess voltage un tell the rest of the cells have reached full charge.

Are there chargers that deliver more than 4-5 Amps anyway? At some point the wire and plug become a problem of their own. Also, isn’t the BMS limiting the current? In which case it would not help to get a more powerful power supply. By the way we call that a charger but in fact it is just a power supply, right? The ‘charger’ is the BMS, isn’t it?

You can, if you have two stock chargers, dual charge the battery. With parallel charging. + to + and - to - solder a diy dual port parallel charge port. Just unplug one charger when they start blinking green/red. Just don't go crazy : you can safely charge at 1C charging. Meaning : if battery have 6 ah. You can have two chargers rated at 2ah (2+2ah=4ah. You charge at 0,66C.

No, it would be next to impossible to monitor individual cell voltage. The chargers are designed to slow down when a specific average cell voltage is reached...which will be a higher total voltage on a 72v charger than say a 48v.......letting the individual cells rest and balance out. If you try and manually watch voltage to shut off when "correct voltage" is reached....it is highly likely that individual cells will be over charged.

I have a 48v 42a battery and the battery I used is a Li-ion 6.4a continuous can I use a charger that uses 15amp continuous or should I stay below the 6.4a of the batteries? I don’t want to damage my batteries or cause a fire

In theory anything below 1C ( here 42a ) charging is acceptable. But I have no idea if it's done with these much bigger batteries like yours. Most battery chargers I've seen charge at 0.3C or closer to 1C but that's with lower capacity batteries. Make sure that if you try to charge at a bigger charge rate than factory that the charge cables can handle the current. Also the current flowing through the conductors need to be taken into consideration. Are the conductors able to handle the amount of charge current? It's possible that the battery can take the current but not the conductors. What kind of load is connected to the battery? If you have an answer on all these questions then you can conclude it yourself.

I think he should have recommended only chargers that have an auto turn off when the battery is full. You can actually start a fire if left on too long. I recently ordered a new charger that was very hot after 2 hours so these do catch on fire if they charge too fast for the bike especially. The charger business said they tested it for safety even.

I accidentally charged a 48 volt battery with a 52 volt charger. Charger light turned green at the end of the charging cycle as normal and pushing the battery check light on the battery showed the battery as being fully charged. Did I damage it?

High chance that it's totally fine. The BMS is designed to protect against overcharging with too high of a voltage. If the BMS had been faulty, it could have exploded. Since you're reading this now, you're probably fine :-)
