Abstract

The invention relates to the technical field of batteries, and in particular discloses an internal-combustion engine starting power supply, which comprises a shell, a battery pack arranged in the shell, and positive and negative terminals extending out of the shell. A battery protection module, a conducting strip and a connecting terminal are arranged in the shell; the battery pack consists of not less than four strings of power lithium iron phosphate cells; the battery protection module is electrically connected with the battery pack through the conducting strip; and the battery protection module is connected with single cells through the connecting terminal. The internal-combustion engine starting power supply has high starting efficiency, the energy consumption of a charge and discharge system is low, and aims of saving oil and protecting environment can be fulfilled.

Description

technical field [0001] The invention relates to the technical field of batteries, in particular to a lithium iron phosphate starting power supply applied to internal combustion engines. Background technique [0002] Most of the existing automobiles still use lead-acid batteries as the starting power supply for automobiles. Lead-acid batteries are batteries made of a highly polluting and toxic metal lead as the main raw material. Lead-acid batteries have the disadvantages of low cycle life (about 300-500 times), serious pollution, need for maintenance, low charge and discharge efficiency, and high self-discharge. Start up, so the battery needs to be removed to recharge or replace with a new battery. [0003] As we all know, lithium batteries have incomparable advantages over other batteries in terms of energy density, specific energy, memory effect, charge and discharge cycle life, and environmental protection. Portable products made of lithium batteries are light in weight,...
