Power Backup Solution for Portable Solar Device

Mobile backup power stores energy through transforming natural renewable energy or household power so that it solves the power cutoff and power supply problems for digital products when used outdoor. It features light weigh, high efficiency and diversity.

  1. Portable solar energy backup power supply solution design requirement:
    With solar energy as source, backup power for portable solar transforms solar energy to electric energy, which is stored by lithium battery and supplies power for outdoor digital products. High-power lithium battery is used as energy-storing device. Dual layer charge mode, solar panel charge by receiving sunlight and charger’s two-way charge, is adopted. In LED form the remaining battery capacity is always accurately displayed t in percentage.

  2. Backup power solution for portable solar
    1. Protection IC: a protection circuit designed mainly for rechargeable lithium battery pack. Because of chemical characteristics of lithium battery, protection functions like smart capacity calculate, overcharge, over discharge, short circuit, over current, etc should be provided to avoid fire and explosion.
    2. Voltage-reducing module part: Solar panel (5v/350mAh) and 5V charger input voltage-reducing module, which has charge function when voltage reduces in the mode of pre charge, and charge under constant voltage and current.
    3. Voltage-raising module part: adopt 5V stable voltage output circuit and max output current can reach 2A.
    4. Charge module part: universal charger 5V/1.5V
    5. LED display part
    6. Solar panel part: transform solar energy into electric power. Output parameter is 5V/350mA.
    7. Lithium battery cell: PL6535134/3.4Ah/3.7V (ATL)
