[Hangshun Training Camp] Three-string lithium battery charging management +741786A

    In daily life, lithium batteries are often fully charged but still being charged, which can easily cause overcharge. Using a protective board alone will cause a voltage drop that affects the capacity. On the other hand, if the discharge voltage is not protected by a protective board, The lower limit of critical discharge voltage can easily lead to too low discharge voltage. Charge and discharge management is carried out through HK32f0, and the AD function is used to realize real-time monitoring of charge and discharge voltage. Under specific circumstances, charge and discharge can be performed and the voltage time can be displayed in real time on the screen; through The relay can realize charging and discharging without voltage drop. The main frequency of 72M can ensure real-time performance. This project can stabilize and protect lithium batteries, their charging circuits and electrical appliances.
