“Invisible Power”: Battery Under the Deck of the DGPI-CSK-004 Electric Scooter
time：2026-08-13
Electric scooters are shuttling between commuters and casual people in a light posture. It is not as heavy as an electric bicycle, nor as flamboyant as an electric motorcycle. Instead, it becomes an elegant solution for "the last kilometer" travel with simple design and flexible posture. Under the bottom plate of this scooter, a carefully hidden battery pack is injecting energy into every slide in an "invisible" way. The battery under the bottom plate of the DGPI-CSK-004 electric scooter launched by Juneng new energy is exactly the "invisible energy" tailored for this micro-travel scene-what it pursues is not the sense of existence, but the company without perception.
I. CSK naming: exclusive genes born for skateboarding
the model code of DGPI-CSK-004 accurately anchors its application scenarios.
"CSK" it is the abbreviation of "City Scooter" and refers to the specific category of City electric Scooter. Different from electric bicycles and electric motorcycles, the design philosophy of scooters is "minimalism" and "lightness"-slim frame, compact wheel hub and flat pedal. Any abrupt addition will destroy this aesthetic pursuit. The naming of DGPI-CSK-004 itself contains a deep understanding of this philosophy: batteries are not "plug-in" accessories, but structural elements "integrated" into the bottom plate.
"004" the internal series code indicates that this is the product line of new energy scooter battery.The fourth generation iteration. From the rear seat mounting type of the first generation to the vertical tube built-in type of the second generation, to the pedal embedded type of the third generation, to the hidden type of the base plate of the 004 generation-every iteration is toward "more invisible, the goal of lighter, lighter and more beautiful is moving forward.
II. 2.7kg extreme lightweight: weight philosophy of micro-Travel
the core competitiveness of electric scooters lies in portability, and the weight of battery pack is the key variable that determines portability.
DGPI-CSK-004 control the weight 2.7kg, this value can be called "extreme" in the field of T-bar scooter battery ". For reference, a lead-acid battery with the same capacity weighs more than 8kg, and the traditional square lithium battery is about 4-5kg. What does 2.7kg mean? It means that users can lift the scooter up and down stairs with one hand, which means that the weight of the folded vehicle is controlled within 12-15kg, which means that female users can easily put the scooter into the trunk of the car or bring it into the office.
This light quantitative achievement originates from the double breakthrough of energy-gathering new energy in cell selection and structural optimization.
Cell level, DGPI-CSK-004 use 18650 cylindrical ternary lithium battery core-- This is the most mature cell specification in the field of consumer electronics and light electric vehicles, with high energy density, compact volume and mature technology. Compared with lithium iron phosphate, ternary materials are in the same body.Providing a higher energy reserve is the key choice to achieve lightweight.
Structural level, battery pack shell adopts the composite structure of high-strength engineering plastic and aluminum alloy frame, which balances the protective strength and weight. The interior is designed without modules, and cell is directly integrated into the floor space, eliminating the weight redundancy of traditional module frames. BMS uses a highly integrated chip scheme to compress the protection circuit, equalization circuit and communication module to the minimum volume.
3. W53mm × D155mm × H300mm: millimeter class game of floor space
the bottom plate of the scooter is battery pack "habitat", but the space here is extremely limited.
The size of DGPI-CSK-004 is W53mm × D155mm × H300mm, this is a "limit size" after precise calculation ". The width of 53mm is just embedded between the longitudinal reinforcing ribs of the scooter bottom plate, the depth of 155mm extends along the length of the bottom plate, and the height of 300mm makes full use of the vertical space between the bottom plate and the frame. This form of "flat strip" makes battery pack completely hidden under the bottom plate and almost invisible from the outside.
Hidden design it is the aesthetic pursuit of gathering energy and new energy. Battery pack after embedded in the bottom plate, the pedal surface is flat without bulges, and the user stands comfortably and visually tidy. The outlet is located at the back end of the base plate, and the cable is along the frame.Part routing, no exposed wiring harness outside. This "integrated" design enables scooters to evolve from "mechanical assemblies" to "industrial designs".
IV. 18650 ternary lithium: big energy in a small figure
DGPI-CSK-004 adopted 18650 cylindrical ternary lithium battery core, this is a classic choice in the field of light travel.
The diameter of 18650 cell (diameter 18mm, height 65mm) is equivalent to that of an AA battery, but it contains several times the energy of AA battery. High energy density ternary material (lithium nickel cobalt manganese oxide) is selected for the new energy source, and the energy density of the monomer can reach more than 250Wh/kg. In the limited floor space of scooter, the high volume utilization rate of 18650 cell makes it the optimal solution of "small space and large energy.
High charge and discharge performance it is another advantage of ternary system. DGPI-CSK-004 supports fast charging, which can be filled in 2-3 hours, meeting the usage habits of city users "with charge"; The discharge platform is flat, and the power output is still stable even in the low power state, there will be no embarrassment of "weakness in the second half.
Split BMS design is the key to security. Charging port is physically separated from the discharge port, which fundamentally eliminates the risk of misoperation during charging. The BMS function covers over-charge protection, over-discharge protection, over-current protection, short-circuit protection, and temperature protection, with a large number of 18650 cell strings.In complex parallel scenarios, ensure that every cell is under security monitoring.
V. Optional communication protocol: from "blind use" to "intelligent management"
DGPI-CSK-004 support optional communication protocol, this is the response of new energy sources to the intelligent trend.
The basic version implements local protection through split-Port BMS to meet basic security requirements; Advanced versions can be selected. Bluetooth communication module, users can view the battery power, estimated battery life, charging and discharging status and health information in real time through the mobile APP. Low battery warning, charging completion reminder, abnormal status alarm-these intelligent functions make scooters evolve from "blind use" to "intelligent management".
For shared scooter operators, optional GPS + Communication Module supports remote positioning, electronic fences, and riding data upload, providing data support for fine operation.
VI. Wide temperature range adaptation: reliable companionship of four seasons in the city
city travel is independent of seasons, and battery pack needs to maintain stable output in the heat and cold.
DGPI-CSK-004 discharge temperature range-20 ℃ to 60 ℃, covering the annual climate of most cities in China. In the morning of-10℃ in the north of winter, the battery can still be discharged normally, and the power attenuation is controlled within 20%; In the afternoon of 40℃ in the south of summer, the power of the BMS is automatically reduced to protect against the risk of overheating. Charging temperature range: 0 ℃ to 45 ℃, it is forbidden to charge at low temperature to prevent lithium evolution, and the current is controlled at high temperature to protect cell.
Storage Temperature: 0 ℃ to 45 ℃ when not in use for a long time, remind users to store the battery in a cool and dry place and keep about 50% of the power to prolong the service life by cell.
DGPI-CSK-004 electric scooter bottom battery, is the exquisite work of "micro-travel energy solution" of energy gathering new energy. It releases portability with the ultimate lightweight of 2.7kg, supports long endurance with 18650 high energy density cell, integrates skateboard aesthetics with hidden design, guards the safety bottom line with split BMS, and embraces the intelligent trend with optional communication protocols.
