Abstract

The invention discloses a battery pack. The battery pack comprises a main battery and at least one balancing battery; and the balancing batteries are connected in series with the main battery. The balancing batteries have characteristics of a low-temperature battery, and the low-temperature discharge power of the balancing batteries is small in an attenuation range, so the battery pack can supply electric energy required during start-up to a load in a low-temperature environment.

Description

【Technical field】 [0001] The present invention relates to a battery power supply circuit, in particular to a battery pack with low temperature compensation, so that the load using the battery pack can have enough energy to start and use at low temperature. 【Background technique】 [0002] In recent years, with the advancement of science and technology, the communication and consumer electronics industries have developed, and many consumer loads, such as: GPS satellite navigation, personal digital assistants, mobile phones, notebook computers, cameras and video cameras, etc., are widely used in public life. . The requirements for the miniaturization, light weight and high performance of these loads are also more than those of ordinary devices. Along with this, the requirements for power supply batteries using these loads are also higher than those of ordinary devices. Among them, for power supply The discharge load and low-temperature discharge characteristics of the battery ...
