HOME / The current is too large and the lithium battery is disconnected - LUP MICROGRID
In theory, it is indeed possible to increase the charging speed by increasing the current. However, if the current is too large, the diffusion speed of lithium ions inside the battery will not keep up with the electron diffusion speed, which will cause the electron-ion transport to be disconnected, which will affect the battery performance, and

Free Quote$begingroup$ @BrianDrummond I need to buy a new laptop battery nowadays so I was thinking about replacing the batteries without cutting the power first (first equalize the new cell voltage with current cell voltage by a 10 ohm resistor to prevent high currents, then wire the new cell to the BMS, after wiring all the new cells, cut the cables of old cells).
Free QuoteYes, it is dangerous to attempt to charge a deeply discharged Lithium battery. 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.
Root cause 2: Too long storage time. Lithium batteries are stored for too long, resulting in excessive capacity loss, internal passivation, and increased internal resistance. Solution: It can be solved by charging and discharging activation. Root cause 3: Abnormal heat.
Identifying common problems with lithium-ion batteries is key to preventing mishaps and ensuring your devices function efficiently. One frequent lithium-ion battery problem is rapid discharge. If you notice your device's battery draining faster than usual, it might be due to a defective battery or an energy-hungry app.
Common problems with lithium-ion batteries include rapid discharge, failure to charge, unexpected shutdowns, and battery drain in idle devices. These issues can relate to energy-demanding apps, damaged ports, or flawed batteries.
Connect with Darren on LinkedIn. The BMS causes lithium batteries to go in to protection mode when overheating, high currents, and high or low voltage. Learn more on how to prevent those and recharge your battery
Root cause 1: High self-discharge, which causes low voltage. Solution: Charge the bare lithium battery directly using the charger with over-voltage protection, but do not use universal charge. It could be quite dangerous. Root cause 2: Uneven current.
