Charge regulator and monitor for spacecraft solar cell/battery system control

摘要: An electronic system for providing fully automatic control of a spacecraft solar cell/battery electrical power system, including the provision continuous telemetry monitoring battery charge state. Circuitry accurately measures, on an ampere-minute basis, charging and discharging functions to maintain in charged condition, with reduction current temperature-dependent trickle value when proper amount has been returned after previous discharge. A bipolar quantizer circuit is utilized monitor discharge operations includes finite time integrator capable supplying output signal pulse each or discharged by predetermined amount. The designed offset factor account inefficiency. Temperature dependent maximum voltage limiting are also provided, along means which operate automatically shunt excess from cell array into instrument package order provide temperature therein.
