In harsh working conditions such as outdoor engineering operations, off-road vehicle power supply, mobile energy storage equipment and short-distance transportation on construction sites, lithium batteries are constantly subjected to severe tests including bumps and vibrations, hard object impacts, drops and collisions, as well as high-frequency mechanical shocks. Ordinary high-voltage lithium batteries feature loose cell arrangement, thin shells and no internal buffer structures. After external impact, they are prone to cell displacement, loose circuits, liquid leakage and even short circuit and fire failures, which greatly shorten battery service life and bring serious potential safety hazards. Focusing on robust impact resistance as the core research and development direction, the72V High Voltage Lithium Power Pack has achieved comprehensive upgrades in three aspects: shell protection, internal buffer structure and cell fixing technology. It is a high-voltage power lithium battery pack suitable for harsh scenarios with full vibration and high impact, solving the common industry problems of poor impact resistance and vibration resistance of lithium batteries in mobile energy storage and vehicle power supply scenarios.

　　In terms of outer shell, this battery pack adopts an integrated thickened die-cast alloy shell, whose extrusion resistance and impact resistance are improved by more than 60% compared with ordinary iron shells. The edge of the shell is equipped with arc-shaped anti-collision wrapping edges to prevent shell cracking caused by direct hard impact on corners. The whole battery pack has passed professional drop tests and mechanical impact tests, and can withstand fixed-point high-strength impact and multi-angle drop collisions. Accidental collisions during outdoor handling and construction work will not damage the internal structure of the battery.

　　Internal buffer protection is its core advantage of impact resistance. High-density flame-retardant buffer foam and layered reinforced partitions are installed inside the battery. Each cell is fixed by dual processes of buckles and double-sided adhesive tapes, preventing cell displacement and mutual friction collision caused by vehicle bumps and equipment vibration. All internal wires adopt high-temperature resistant reinforced harnesses fixed firmly by shockproof wire clips, avoiding wire falling off and poor contact caused by long-term high-frequency vibration, and ensuring stable circuit conduction under impact conditions.

　　In addition, this 72V high-voltage lithium battery pack retains excellent high-voltage discharge and energy storage performance with stable high-voltage output without voltage drop, meeting the continuous power supply demand of high-power equipment. It is equipped with an upgraded shock-resistant intelligent BMS system that resists voltage detection errors caused by vibration, and can accurately monitor cell status during impact and vibration. It also supports multiple electrical protections including overcharge, overdischarge, short circuit and high and low temperature protection. With qualified dustproof and waterproof performance as well as super strong impact resistance, it can be applied to various high-impact scenarios including construction sites, wild fields, off-road vehicles and mobile emergency energy storage for a long time.

　　Free from bumps and vibrations and resistant to external impacts, the 72V High Voltage Lithium Power Pack integrates comprehensive impact protection design, stable high-voltage power output and extreme working condition protection capabilities. It enables long-term and stable operation of high-voltage lithium batteries in complex vibration and high-impact environments, and provides safer, firmer and more durable energy support for mobile high-voltage energy storage and power supply scenarios.
