Abstract

The invention discloses a 12V automobile emergency starting power supply, which comprises a battery pack module; a load end; and an open circuit protection module, which includes a first-stage open circuit protector and a second-stage open circuit protector connected in series between the battery pack module and the load end The protector, the first stage circuit breaker includes a relay, the second stage circuit breaker includes a plurality of parallel thermistors, the circuit breaker protection module also includes a plurality of heating resistors arranged adjacent to each thermistor, and the plurality of heating resistors phase-parallel connection; the control device is used to control the relay and to control multiple heating resistors. Implementing the technical solution of the present invention can solve the technical problem that the ternary lithium battery cannot be used to make a 12V automobile emergency starting power supply in the prior art; implementing the technical solution of the present invention can realize preventing the reverse charging of the ternary lithium battery, overcurrent discharge and The battery is overheated to ensure the safety of the system.

Description

technical field [0001] The invention relates to an electrical device used in the field of automobiles, in particular to a 12V emergency starting power supply for automobiles. 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 non-useful device used in ...
