The “energy giant” of heavy-duty AGVs: In-depth analysis of the DGPI-16S100Ah-031 lithium battery pack
time：2026-08-10
In the deep water area of intelligent logistics, heavy duty AGVs (automatic guided vehicles) are undertaking more and more arduous missions. They shuttle through the assembly line of automobile factories, the raw material warehouse of iron and steel enterprises, the container yard of port terminals, and carry several tons of materials, which is an indispensable "ground aircraft carrier" in the industrial 4.0 era ". Deep in the chassis of this steel monster, a battery pack with high energy, high power and high reliability is the core engine that determines whether it can complete the leap from "light load test" to "heavy load gallop. The DGPI-16S100Ah-031 heavy-duty AGV lithium battery pack launched by new energy sources is exactly the "energy monster" tailored for this extreme scenario ".
1.48V/100Ah:4.8kWh of energy reserve, the endurance of heavy load scenarios
DGPI-16S100Ah-031 the most shocking technical index is its 4.8kWh of super-large energy reserve.
"16s" represents 16 series of lithium iron phosphate batteries series, the nominal voltage 48V;"100Ah" capacity with this voltage platform, the whole package energy reaches 4800Wh. This value can be called "Monster level" in the field of AGV batteries-taking a typical heavy-duty AGV as an example, the power consumption of the whole machine is about 800-1200W (including drive motor, hydraulic lifting and control system), the energy reserve of 4.8kWh can support 4-6 hours of continuous heavy duty operation. For intermittent storage scenarios (driving-lifting-putting down-returning), the actual battery life can reach 8-10 hours, easily covering a complete shift or even double shift operation.
≤ 100A charging current quick Charge of 1C is supported, which means that battery pack can be replenished from 0 to 80% within 1 hour. The short power supplement between lunch break can "revive the AGV with full blood" and support the continuous fighting in the afternoon. This fast charging capability is of decisive economic value for heavy load logistics scenarios that pursue the maximization of equipment utilization.
2. 200A peak discharge: the instantaneous explosive force of heavy load lifting
the core challenge of heavy-duty AGVs is not to drive at a constant speed, peak power requirements for startup, acceleration, and lifting.
The discharge performance of DGPI-16S100Ah-031 is powerful: ≤ 120A continuous discharge current to meet the power requirements of conventional driving and lifting; instantaneous discharge current of 200A to provide sufficient margin for burst peak load. Take a 2-ton heavy-duty AGV as an example, the motor current can reach more than 150A when fully loaded, and the hydraulic pump current at the moment of lifting can reach a peak reserve of 180 A- -200A, make sure that the AGV does not "drop the chain" under extreme working conditions ".
The realization of this discharge capability originates from the selection and electrical design of energy-gathering new energy in cell.A double breakthrough in the world.
Cell level, DGPI-16S100Ah-031 use 32700 cylindrical lithium iron phosphate batteries-- Diameter mm, height 70mm, larger than the common 18650/21700 cell, higher monomer capacity and lower internal resistance. The larger cross-sectional area of 32700 cell reduces the current density, reduces polarization heating, and lays a physical foundation for high-rate discharge.
Electrical connection layer, energy gathering new energy adopts multi-pole lug parallel design, which distributes 16 series of cell current paths to dozens of parallel branches to reduce single point resistance and heat generation. Copper bar cross-sectional area is optimized by thermal simulation to ensure that the temperature rise does not exceed 15℃ under 200A peak current.
III. 52kg/L600mm: energy density art in compact body
in the design of heavy load AGVS, battery pack weight directly deducts the payload, and the size determines the chassis layout. 52kg ± 1kg weight control and L600mm × W200mm × H300mm slender size, is the subtle achievement of energy gathering new energy structure engineering.
box use metal Shell design, the surface is sprayed with plastic to resist impact, corrosion and electromagnetic interference. The slender cuboid form (length 600mm, width 200mm, height 300mm) can be embedded into the longitudinal space of the AGV chassis, with low center of gravity and good stability, and does not occupy fork or the space of the loading platform. The embedded handle design at the top supports quick replacement of forklift or hoisting equipment; Anderson connector and Aviation plug on the side realize tool-free insertion and removal, and the power exchange time is controlled within 5 minutes.
≤ 100 Mohm finished product internal resistance, is a key indicator of electrical efficiency. The lower the internal resistance, the smaller the heating loss during charging and discharging, and the higher the system efficiency. Through cell selection, copper bar optimization and welding process control, the new energy gathering energy compresses the internal resistance of the whole package to below 100 Mohm, and the temperature rise can be controlled during 100A charging and discharging, ensuring a long cycle life.
4. Intelligent BMS: security guardian under high voltage and high current
the 48V/200A electrical specification puts forward extremely high requirements for the safety control of BMS.
DGPI-16S100Ah-031 equipped with new energy sources self-developed smart BMS, support RS485 and RS232 dual communication interface, can interact with AGV scheduling system, charging pile and upper monitoring platform in real time. O & M personnel canThrough remote monitoring of the battery status of each device in the background, the leap from "passive maintenance" to "predictive maintenance" can be realized.
Six-weight protection build an industrial security line:
-
short circuit protection: millisecond detection and instantaneous fuse to prevent thermal runaway caused by accidental short circuit;
-
overcharge Protection: when the single voltage exceeds 3.65V or the total voltage exceeds 58.4V, the charging is automatically cut off;
-
over-release protection: shutdown protection when the single voltage is lower than 2.5V or the total voltage is lower than 40V;
-
overcurrent protection: when the continuous discharge exceeds 120A or the peak value exceeds 200A, the current is limited step by step;
-
Temperature Protection: real-time monitoring of cell temperature, power reduction protection at high temperature, pre-heating at low temperature and then starting;
-
active equilibrium: transfer high voltage cell energy to low voltage cell at the end of charging, control the serial differential pressure within 20mV, and prolong the cycle life of the whole package.
V. 32700 cylinder cell: industrial grade verification of large cylinder route
DGPI-16S100Ah-031 adopted 32700 cylindrical lithium iron phosphate batteries, this choice is quite characteristic in the current market dominated by square cell.
The advantage of 32700 cell lies in consistency and manufacturability. The symmetry of cylindrical structure makes it easy to realize automation and high precision control in winding, liquid injection, formation and other processes; Standardized size specifications facilitate mass production and quality traceability. Aggregate energy new energy performs full inspection and distribution for cell of each batch, and the capacity deviation is controlled within 1% to eliminate the "short board effect" caused by inconsistency from the source ".
the chemical system of lithium iron phosphate provides double guarantee of safety and cycle life. Compared with ternary materials, the thermal runaway temperature of lithium iron phosphate is higher (>500℃), and it is more stable in abuse scenarios such as acupuncture and extrusion; The cycle life can reach more than 3,000 times, in high-frequency scenarios where heavy-duty AGVs are used, the full-lifecycle cost is more advantageous.
VI. 2000 cycles: longevity economics in overloaded scenarios
the battery replacement cost of heavy-duty AGVs is high and the shutdown loss is huge. Cycle life is the core indicator of economy.
DGPI-16S100Ah-031 commitment more than 2000 cycle life, under the high-frequency use of daily uniform charging, the battery life can reach 5-6 years. This longevity performance stems from the triple control:
A brand cell optional-- 32700 cell of first-line suppliers such as Ningde era and Guoxuan Gaoke have been verified by the market for material purity and process consistency;
conservative SOC window-- The default operating range is 10%-90%, and the safety margin is reserved for cell to avoid irreversible damage of deep charge and discharge;
intelligent temperature control strategy-- BMS dynamically adjusts the charge and discharge current according to the temperature of cell, reduces the power protection at high temperature, and restarts after pre-heating at low temperature to ensure the attenuation consistency under all climatic conditions.
DGPI-16S100Ah-031 heavy load AGV lithium battery pack it is the peak work of the concept of "industrial energy solution" for new energy sources. It supports long endurance with 48V/100Ah super-large energy reserve, meets heavy load explosive force with 200A peak discharge capacity, releases payload with 52kg compact design, and guards the safety of the whole life cycle with intelligent BMS.
