Abstract
Solar power pack apparatus adaptable for powering emergency equipment at remote locations includes a solar cell array, a rechargeable battery pack, a long shelf-life primary battery pack and switching circuitry interconnecting these elements to provide upon demand immediate and continuous supply of electrical power over extended periods of time notwithstanding environmental conditions which would render unsuitable conventional emergency-use reserve power packs.
Claims9
Solar power pack apparatus comprising:
- photovoltaic cell means;
- first electrochemical cell battery means in circuit with said photovoltaic cell means;
- second electrochemical cell battery means having a watthour capacity sufficient to increase the watthour capacity of said first electrochemical cell battery means when said second electrochemical cell battery means is electrically coupled to said first electrochemical cell battery means;
- electrical coupling means operative to selectively couple said first and second electrochemical cell battery means;
- and electrical load terminal means adaptable for connection thereto of an electrical load in circuit with said electrical coupling means.
