Function Documentation

◆ Power_Control_Charge()

void Power_Control_Charge ( bool charge )

This function ensures that the battery is charging. "set MPPT to input which enables battery charging, but only after checking keep alive and temperature limit".

Test:

(ID POWER_CONT_H_T3) (SEV 1) Make sure the battery charges when this function is called.

(ID POWER_CONT_H_T4) (SEV 1) When mppt keep alive is enabled, make sure that the battery charges.

(ID POWER_CONT_H_T5) (SEV 1) When mppt temperature switch is enabled, make sure the battery doesn't charge.

(ID POWER_CONT_H_T6) (SEV 1) When the charge boolean is TRUE, is allows the battery to charge.

(ID POWER_CONT_H_T14) (SEV 1) When the charge boolean is FALSe, is prevents the battery to charge.

Parameters

charge The option to charge the battery or turn off the MPPT.
