Integrated Battery Chargers

2022
Integrated battery chargers (IBCs) have been proposed as a low-weight, low-volume, and high-power solution to conventional conductive chargers. However, the design of such chargers is complicated, requiring special components or control techniques to solve inherent issues (such as galvanic isolation, torque generation, and system reconfiguration ...

Solar Battery Chargers for NiMH Batteries

IEEE 36th Conference on Power Electronics Specialists, 2005., 2006
This paper proposes new solar battery chargers for NiMH batteries. First, it is shown that existing charge-control methods can fail when charging by solar arrays in changing environmental conditions. This article discusses the reasons for the failure and introduces new voltage and temperature-based charge- control techniques.

Solar battery charger for NiMH batteries

2008 International Symposium on Power Electronics, Electrical Drives, Automation and Motion, 2008
In this paper a solar battery charging procedure for NiHM batteries is presented. The article shows how it is possible to detect a true full state of charge avoiding false charge termination due to changing illumination conditions.

Current-Pumped Battery Charger

IEEE Transactions on Industrial Electronics, 2008
A novel current-pumped battery charger (CPBC) is proposed in this paper to increase the Li-ion battery charging performance. A complete charging process, consisting of three subprocesses, namely: 1) the bulk current charging process; 2) the pulsed current charging process; and 3) the pulsed float charging process, can be automatically implemented by ...
