Abstract

The present invention discloses a 12V jump starter using a ternary lithium battery. The 12V jump starter using the ternary lithium battery comprises a battery pack module used for outputting a DC externally and comprising three lithium battery packs which are connected in series mutually, wherein each lithium battery pack comprises one or a plurality of ternary lithium batteries which are connected in parallel mutually; and a load end which is in series connection with the battery pack module and is used to receive the voltage of the battery pack module and output externally. The 12V jump starter using the ternary lithium battery is characterized by also comprising a relay which is in series connection between the battery pack module and the load end; a control device used for controlling the relay. By implementing the technical scheme of the present invention, the technical problem in the prior art that the 12V jump starter can not be manufactured by the ternary lithium battery can be solved, the reverse charging, the overcurrent discharging and the battery overheating of the ternary lithium battery can be prevented, and the system safety is guaranteed.

Description

technical field [0001] The invention relates to an electrical device used in the field of automobiles, in particular to a 12V automobile emergency starting power supply using a ternary lithium battery. Background technique [0002] The 12V car emergency starter power supply is used for car starting under extreme conditions, such as low temperature starting. Provide high current in a short time to start the car. Under extreme conditions, the instantaneous locked-rotor current can reach more than 1500A, which is a typical short-time high-current discharge situation. A 12V car is generally a car with a starting voltage of 12V. Generally speaking, this type of car is a small car such as a passenger car. [0003] Most of the 12V automotive jump-starter products on the market are made of lead-acid batteries for many years. Lead-acid batteries may cause serious environmental pollution in the process of manufacture, use, and recycling; and the emergency starting power supply is a...
