I will assume your data is in a table:

type=["charge";"discharge";"discharge";"charge"];
data=(1:4)';
T=table(type,data)

T = 4×2 table
       type        data
    ___________    ____

    "charge"        1  
    "discharge"     2  
    "discharge"     3  
    "charge"        4  

Tcharge=T(T.type=="charge",:)

Tcharge = 2×2 table
      type      data
    ________    ____

    "charge"     1  
    "charge"     4  

Tdischarge=T(T.type=="discharge",:)

Tdischarge = 2×2 table
       type        data
    ___________    ____

    "discharge"     2  
    "discharge"     3
