Could you provide the meanings of metadata?

Metadata	Details	Meaning (We just guess them!)
summary	cycle	cycle number
	QDischarge (MATLAB) / QD (Python)	electric quantity - during discharge or output?
	QCharge (MATLAB) / QC (Python)	electric quantity - during charge or input?
	IR	internal resistence?
	Tmax	maximum temperature
	Tavg	average temperature
	Tmin	minimum temperature
	chargetime	duration for charge
cycles	t	timestamp
	I	current
	V	voltage
	T	temperature
	Tdlin	linear interpolations for temperature - Why are they rising? during discharge?
	Qc	electric quantity during charge
	Qd	electric quantity during discharge
	Qdlin	linear interpolations for electric quantity - Why are they rising? during discharge?
	discharge_dQdV (MATLAB) / dQdV (Python)	dQ/dV? during discharge?
Vdlin (Available for MATLAB Data)	-	linear interpolations from 3.5V to 2V - Why are they identical for all cells?

Hi! Your dataset provides multivariate time series (cycles) and covariates for each cycle (summary), and we want to take use of them in our deep learning model.
We are now struggling to get the meanings of the above metadata and need your help!
Some has been guessed but we are unsure. The question marks (?) denote what we can't figure out.

• IR = internal resistance
• Tdlin, Qdlin, Vdlin are all during discharge
