Abstract

The invention relates to a charger, in particular to a lithium battery charger by which the purpose of fast charging lithium batteries can be realized. The charger comprises a casing and an operation panel, wherein a groove which can be used for placing rechargeable batteries is arranged on the casing; an inner cavity formed by the casing comprises a charging circuit; the charging circuit has a fast charging mode which uses large current for charging rechargeable batteries; the charging circuit also has a normal charging mode which uses normal current for charging rechargeable batteries; and the switching of the two charging modes is controlled by a control circuit. The charger of the invention provides an ultra-fast charging scheme which has selectable charging modes and can be controlled by battery temperature change, and the purpose of excessively outputting the charging power can be realized under the conditions of low power and proper temperature change tendency to safely supply certain capacity (energy) to batteries in a short time to finish a certain amount of works.

Description

technical field [0001] The invention relates to a charger, in particular to a lithium battery charger, which can realize rapid charging of the lithium battery. Background technique [0002] When customers use lithium batteries, the following situations generally occur: when a certain amount of work needs to be completed or a small part of work is left to be completed, the battery pack is found to be insufficient, and the user needs a small part of the capacity (such as a% of the battery capacity) to complete the work (no need for a full capacity battery), and hope that there is a charger mode that can complete the charging process of a% of the battery capacity in a very short time, such as 100S-200S. However, current fast-charging Li-ion battery chargers are expensive to design and have poor mode selectivity. Contents of the invention [0003] The technical problem to be solved by the present invention is to overcome the defects in the prior art, realize low cost, and p...
