US 5,668,461 A · Reserve battery having temperture compensation

Abstract

An electronic control system for a reserve, energy sourced, or deferred action battery that determines start-up temperature and voltage conditions to determine the necessary amount of charge to deliver from a reserve battery to a discharged battery. A temperature sensor is used to measure the ambient temperature and operating temperature of the electronic control system. A target charge value is selected based on the ambient temperature and startup voltage information. The operating temperature of the electronics control system is monitored to ensure the most efficient and reliable delivery of charge. Indications are provided to the user to provide information regarding charging status, connection status, and voltage levels.

Dependent claims

In a battery charging system for recharging a discharged battery from a reserve battery, an apparatus for providing a charge from said reserve battery to said discharged battery as a function of an ambient temperature of said battery charging system, said apparatus comprising:

ambient temperature measurement means for determining an ambient temperature value representative of said ambient temperature,
selection means, responsive to said ambient temperature value, for selecting a predetermined target charge value, said target charge value representing the amount of said charge to be delivered from said reserve battery to said discharged battery;
and
control means for delivering said charge from said reserve battery to said discharged battery in an amount substantially equal to said target charge value.
