Is there a relationship between the discharge of a 15 Ah lithium battery and the battery protection

The discharge of the 15 Ah lithium battery is linked to the battery protection board to prevent excessive discharge.

Lithium batteries or lithium battery protection boards should be added inside to prevent battery overcharging and overdischarging, which achieved the protective effect. The protection function of lithium batteries is usually supplemented by a protection circuit board and current devices such as PTC or TCO. Lithium batteries are so widely used that people pay more and more attention to the safety of lithium batteries themselves, so lithium battery protection boards have become important.

The lithium battery protection board is a charge and discharge protection for lithium batteries connected in series. When fully charged, it can guarantee que the voltage difference between each battery is less than the set value, thereby achieving equal charging of each battery in the battery pack, effectively improving the charging effect in series charging mode.

At the same time, it detects the overvoltage, undervoltage, overcurrent, short circuit and overheating status of each cell of the lithium battery to protect and extend the service life drums. Undervoltage protection prevents each battery from being damaged due to over-discharge when used for discharge. There is currently no official information suggesting that lithium batteries can be used without protective plates. Generally, batteries have protective plates, and the use of protective plates is also to ensure the safety of the battery. But different types of lithium battery protection boards have different fdifferent anointings.

How to check whether the overcharge and overdischarge function of lithium battery protection board meets the standard? Tested with lithium battery protection board tester. Based on in-depth research on the production process of lithium battery protection boards, Hongda battery protection board tester is developed using the principle of battery charge and discharge capacity simulation. It has the characteristics of complete functions, simple operation and fast detection speed.

1. Overload protection voltage measuring range: --------------------------4,150---4,500V ±1mV p>

2. Overload protection recovery voltage measurement range: -------------------4,200---3,800V ±1mV

3. Overdischarge protection voltage measurement range: -----------------------3.200---2.000V ±1mV

4. Overdischarge protection recovery voltage measuring range: -------------------2,500---3,500V ±1mV

5 . : - -----------------------------------0---10A ±0.1A

< p>6. Quiescent current measuring range:---------------------------------0.0----- ---1000.0uA ±1uA

7. Internal resistance measurement range:--------------------------------0---200 mΩ±1 mΩ< /p>

8. Identify the resistance measurement range: ---------------------------------- 0.1-- -999, 9K ±0.1K

9. Overload protection delay time: --------------------------- - ----0---5000 mS ±1 mS (1 mS=0.001 seconds)

10. Overdischarge protection delay: ---------------- -- ----------0--------1000 mS ±1mS< /p>

11. Overcurrent protection delay time: ---------- -- ----------0---100 mS ±1 mS

Test speed:

1) Quick test: 1 second fastest (only pfor the single-cell protection board with 10mS overload protection delay)

2) Accurate test: 1.7 seconds fastest (only for the single-cell protection board with overload protection delay against overloads of 10 mS))

< p>Note: The test time depends entirely on the delay settings of the protection board under test. If the delay time is short, the testing time will be short, otherwise the testing time will be longer.
