The invention relates to a
lithium battery charging
system, and relates to the technical field of battery charging, the
lithium battery charging
system comprises a charging module, a detection module and a
data processing module, and also comprises a battery
health assessment module used for collecting battery cycle index,
internal resistance and capacity attenuation parameters, and constructing a battery health state assessment model; the
power grid interaction module is used for acquiring real-time
electricity price data and a
power grid load state; the environment sensing module comprises an environment temperature and
humidity sensor and is used for collecting environment temperature and
humidity parameters; and the AI prediction module is constructed based on a
deep learning network and is used for predicting a battery state change trend. According to the invention, the battery
health evaluation module is arranged to collect parameters such as cycle index,
internal resistance and capacity
fading rate to construct the SOH evaluation model, the problem of single dimension of battery health state evaluation in the prior art is solved, the aging degree of the battery can be accurately identified, and the risk of
overcharge and undercharge of the aged battery due to improper power
adaptation is avoided.
