  • System and method for charging auxiliary batteries
    Patent number: 5481175
    Abstract: A system and method for charging an auxiliary battery (107) that drives an auxiliary load (109) includes a regulator (111', 223) coupled to an auxiliary battery (107). The regulator (111', 223) provides a charge current (121') that is variable dependent on a parameter of a control signal (203). Preferably, the parameter is an amplitude. A switch (113') provides a coupling and a decoupling between the auxiliary battery (107) and the auxiliary load (109). A control device (115') decouples the auxiliary battery (107) from the auxiliary load (109) via the switch (113'), and then provides the control signal (203) to the regulator (111', 223). By effecting this action, the regulator (111', 223) provides the variable charge current (121') to the auxiliary battery (107) dependent on the amplitude of the control signal (203).
