Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of lithium ion battery replacement, and particularly relates to a shock-resistant lithium ion battery pack for battery replacement and a battery replacement method thereof. BACKGROUND

[0002] The traditional assembly method of power lithium ion batteries is to first assemble the positive electrode sheet, the negative electrode sheet and the separator by using the lamination method, that is, the sheet-shaped positive electrode sheet, the negative electrode sheet and the separator are overlapped by using the unit of "negative electrode sheet, separator, positive electrode sheet, separator", and a negative electrode sheet is stacked on the last unit to form the battery.

[0003] When the electric vehicle is running, especially on uneven road surfaces, the vehicle body vibrates greatly, and under the vibration condition, the relative movement between the battery electrode sheets and the battery core and the shell is prone to occur, and the performance instability phenomenon occurs.

[0004] At the same time, in the field of electric vehicles, with the continuous increase of the number of domestic electric vehicles, a large number of people who use electric vehicles for a long time, a large number of delivery and express delivery riders, and shared electric vehicles that collect battery packs for replacement are increasingly facing some problems such as "inconvenient charging", "low charging speed", "many safety hazards", "insufficient endurance", "long waiting time", "low efficiency", etc. Under this background, the "battery replacement" mode is proposed to solve the pain points of the traditional charging mode, improve the replacement efficiency, and meet the demand for endurance mileage. Compared with lead-acid batteries and ternary lithium ion batteries, the service life of the lithium iron phosphate power soft-pack lithium ion battery is much longer than that of lead-acid batteries and ternary lithium ion batteries, which can save the use cost, and more importantly, the safety of the lithium iron phosphate power soft-pack lithium ion battery can be guaranteed. With the increase of battery replacement users, the number of stolen batteries increases year by year, which brings great instability to the riders, and the fear of battery theft becomes a problem for every rider user. With the increase in the number of batteries, battery management, battery data processing, analysis and other problems are becoming increasingly important, and the big data statistics, analysis and processing of the monitoring background urgently need to be met. Therefore, the battery replacement cabinet emerges as the times require, which can be used for battery pack charging and is convenient for taking, but when the battery pack is placed in the battery replacement cabinet, it needs to be connected for charging, the battery replacement rate is low, and for shared electric vehicles that collect battery packs for replacement, it will affect the replacement efficiency of the replacement operators.
