Title:
BATTERY CHARGING/DISCHARGING METHOD AND CIRCUIT
Document Type and Number:
WIPO Patent Application WO/2017/118433
Kind Code:
A1
Abstract:
Disclosed are a battery charging/discharging method and circuit, falling within the technical field of electronics. The battery charging/discharging circuit comprises a power supply, a load and at least one battery pack, wherein a first electrode of the power supply and a first electrode of the load are connected to a first node, and a second electrode of the power supply and a second electrode of the load are connected to a second node. The charging/discharging circuit further comprises loop circuits corresponding to battery packs on a one-to-one basis, wherein a first electrode of a battery pack is connected to the first node, and a loop circuit is located between a second electrode of the battery pack and the second node. A loop assembly comprises: a first switch, a second switch and a diode, wherein a first end of the first switch and a first end of the second switch are both connected to a second electrode of a battery pack; a second end of the second switch is connected to a first electrode of the diode; and a second end of the first switch and a second electrode of the diode are connected to a third node. The technical solution can effectively solve the problems that a lithium-iron battery cannot be subjected to floating charging for a long time and charging/discharging is uncontrollable due to a transient large current during a battery switching-on period.
