The portable solar energy system stores electrical energy generated by a solar panel, which is made of an array of photovoltaic cells, in a dc storage battery, and upon demand converts the dc voltage of the battery to an ac output suitable for supplying conventional electrical appliances. The battery is a sealed lead-acid type and may be an Absorbed Glass Mat (AGM) battery. The system includes an energy storage and converting unit, which houses the battery and a dc-to-ac inverter. The inverter converts the stored energy of the battery, supplied at a low dc voltage, into the ac voltage and current required for supplying conventional appliances. A charge controller manages the flow of current from the solar panel to optimize the state of charge of the battery and to maximize the useful life of the battery. Additional circuitry monitors the discharge level of the battery to limit deep discharging.

A schedule recording section (4) records a user's schedule. A SOC (state-of-charge) optimization planning section (5) plans the SOC of a rechargeable battery (21) based on the user's schedule. The planned control target SOC is optimized through a comparison between the continuous charging characteristic of the rechargeable battery (21) and the length of an operable period or the amount of electric power to be secured at the time of battery-powered operation. For example, a control target SOC is set at a full charge in the proximity of the period during which a battery-powered operation time is expected to be long. A control target SOC is set lower enough than a full charge in the period during which a connection to an external power supply (A) by the AC adapter (11) is expected to continue for a long time. A power-supply control section (3) controls the charge and discharge of the rechargeable battery (21) according to a plan for the optimization of the SOC.

A power supply control section calculates a target charge/discharge current of a secondary power supply apparatus based on an actual charged amount and a target charged amount of the secondary power supply apparatus, and feedback-controls the stepped-up voltage of a step-up circuit such that an actual charge/discharge current detected by a secondary current sensor coincides with a target charge/discharge current. When the actual charged amount (1) is equal to or greater than the target charged amount, the target charge/discharge current is set to zero to prevent overcharging, and (2) is less than the target charged amount, a target charge current corresponding to a capacity margin of the step-up circuit is set to quickly charge the secondary power supply apparatus. When the output of the step-up circuit has no margin, the target charge/discharge current is set to zero.

The present invention provides methods for enhancing the fragmentation of peptides for mass spectrometry by modifying the peptides with a tagging reagent containing a functional group, such as a tertiary amine, having a greater gas-phase basicity than the amide backbone of the peptide. These high gas-phase basicity functional groups are attached to a peptide by reacting the tagging reagent to one or more available carboxylic acid groups of the peptide. Linking these high gas-phase functional groups to the peptides leads to higher charge state ions from electrospray ionization mass spectrometry (ESI-MS), which fragment more extensively during fragmentation techniques, particularly non-ergodic fragmentation techniques such as electron capture dissociation (ECD) and electron transfer dissociation (ETD).
