Over the past decade, global charging infrastructure development has predominantly focused on stationary charging stations. From AC slow charging to DC fast charging and liquid-cooled supercharging, the technology of these stations has continuously evolved, yet their inherent physical limitations remain unresolved. The following four pain points have become increasingly prominent in today's increasingly complex mobility scenarios:
Fixed charging stations cannot be moved. When an electric vehicle breaks down due to depleted battery and becomes stranded on a highway, remote mountain road, or narrow passage in an underground garage, moving the fixed charging station is ineffective. The only current solution is towing—the faulty vehicle to the nearest fixed charging station. This process is not only time-consuming (average waiting and towing time: 2–4 hours) but also costly (average European towing service fee: €150–400). More critically, towing operations pose significant safety risks during extreme weather conditions (blizzards, high temperatures) or at night.
Fixed charging stations must be connected to the power grid. In areas with insufficient grid capacity—such as old urban districts, remote tourist attractions, and temporary event venues—the installation of fixed chargers often entails high grid expansion costs (with individual station upgrades costing €50,000–€100,000) and lengthy approval processes (6–18 months). Moreover, once installed, the locations of fixed chargers are fixed and cannot be flexibly adjusted according to fluctuations in pedestrian and vehicular traffic. In seasonal high-demand areas (e.g., summer beaches or winter ski resorts), these chargers become idle assets during off-seasons but face supply shortages during peak seasons.
Natural disasters (floods, earthquakes, blizzards) often cause power grid outages. In such situations, fixed charging stations become completely ineffective. Emergency vehicles (ambulances, fire trucks, rescue command vehicles) and electric vehicles of trapped individuals face the dilemma of having vehicles but no electricity. Although traditional fuel-powered generators can provide power, they generate significant noise, emit harmful gases, and are unsuitable for use in enclosed spaces such as underground garages and tunnels.
While stationary ultra-fast charging stations can charge batteries from 20% to 80% in 15–30 minutes, prolonged high-rate charging subjects the power battery to cumulative stress damage, which may accelerate capacity degradation over time. In non-urgent scenarios, users require not rapid energy replenishment but safe, controlled, and battery-friendly medium-rate charging—a need often overlooked in stationary charging systems.
Summary: Fixed charging stations serve as the backbone of charging networks, yet they fail to cover "end-user locations" and "blind spots." The mobile rescue energy storage charging solution was specifically developed to address this gap.
The mobile rescue energy storage and charging system is not a replacement for fixed charging stations, but rather a complementary asset. The following six scenarios represent the core application areas of this solution:
When a vehicle breaks down due to a dead battery, a mobile rescue charging vehicle can swiftly arrive at the scene to provide emergency power replenishment. The standard rescue procedure is: receiving a distress call → dispatching a mobile charging unit → arriving at the scene (with a response time typically within 30–60 minutes) → connecting to the faulty vehicle → supplying 15–30 kWh of emergency power (enough to enable the vehicle to travel 80–150 kilometers to the nearest fixed charging station). The core value of this approach lies in avoiding towing, thereby saving time and costs.
During peak holiday travel periods, fixed charging stations at highway service areas often experience long queues. Mobile rescue charging units can be deployed as temporary capacity expansion equipment at these facilities, increasing charging capacity without requiring grid upgrades. When the queue exceeds five vehicles, introducing a mobile charging unit reduces the average waiting time by 40%-60%. Service area operators can charge users an additional fee under the "emergency service fee" model, generating daily revenues of €500–€1,000 during peak seasons.
Remote scenic areas, wilderness campsites, mining zones, and farms often lack grid coverage or have extremely limited power capacity. Fixed charging stations cannot be deployed in these regions. Mobile rescue charging units can establish "green energy refueling points" through a self-sufficient model integrating photovoltaics, energy storage, and charging capabilities. During daytime, solar power charges the energy storage system; at night or on cloudy days, they provide charging services for vehicles. Additionally, their AC/DC dual-mode output enables simultaneous power supply to electric tools, lighting equipment, and communication devices, making them the "energy hub" for remote work sites.
Large-scale events such as music festivals, sporting competitions, and exhibitions generate temporary charging demands—not only from operational vehicles (security, logistics, and broadcast vehicles) but also from private electric vehicles used by participants. In these scenarios, deploying fixed charging stations is neither economical nor practical. Mobile rescue charging units can be deployed before events and removed afterward, offered on a daily rental basis to flexibly meet needs. Experience from a major European music festival demonstrated that deploying four such units could supply energy for approximately 300 electric vehicles during the event, resulting in a 35% increase in user satisfaction.
In cases where power grid interruptions occur due to natural disasters such as floods, earthquakes, or blizzards, the mobile rescue charging unit can serve as an emergency power source. Its core advantages include:
Silent operation: Compared to fuel-powered generators, energy storage systems operate noiselessly and do not interfere with rescue operations or the rest of affected populations.
Zero emissions: Can be safely used in enclosed spaces (such as underground garages and shelters)
Multi-scenario adaptability: The AC output can power lighting, communication, and medical equipment; the DC output can directly recharge electric rescue vehicles (such as electric ambulances and electric fire trucks).
Users such as logistics fleets, bus companies, and ride-sharing platforms that operate large numbers of electric vehicles frequently encounter situations where "individual vehicles cannot complete their daily tasks due to insufficient battery power" during maintenance operations. Mobile rescue charging units serve as portable energy replenishment tools within facilities, providing backup charging services when fixed charging stations are occupied or malfunctioning. Additionally, during routine vehicle maintenance and inspections, these mobile charging units deliver stable DC power without requiring activation of the vehicle's high-voltage systems.
To meet the aforementioned requirements, we have developed a highly integrated mobile rescue energy storage and charging system featuring multi-source input and dual-mode output. Centered on energy storage, the system supports charging from photovoltaic, AC grid, and DC sources, while simultaneously delivering both AC and DC power to enable flexible energy replenishment for various electrical devices and electric vehicles.

Our mobile energy storage unit supports three charging methods, ensuring reliable power replenishment in any environment:
Photovoltaic Input: In remote or off-grid environments, flexible photovoltaic panels (with a foldable design for portability) can be connected externally to utilize solar energy for charging the energy storage system. Under sufficient sunlight conditions, a 5 kWp photovoltaic array generates an average daily output of 20–25 kWh, sufficient to power 2–3 basic rescue operations.
AC power input: In locations with mains electricity (service areas, parking lots, maintenance workshops), the energy storage system can be charged using standard AC sockets. The charging time depends on the storage capacity and connected power (a 50 kWh unit requires approximately 7 hours of 7 kW AC charging to fully charge).
DC fast-charging input: At highway service areas or fixed fast-charging stations, existing DC fast-charging piles can be utilized to rapidly recharge our mobile energy storage units. With 60kW DC fast-charging, a 50kWh unit can be charged from 20% to 80% in just 50 minutes. The unique value of this design lies in the ability of the mobile unit itself to "borrow" fixed charging infrastructure for rapid recharging, enabling coordinated scheduling of both mobile and fixed charging systems.
Traditional mobile energy storage products typically offer either AC output (for standard electrical appliances only) or DC output (for charging electric vehicles only). Our solution supports simultaneous AC and DC output without mutual interference:
DC output (200-1000V,20-60kW): Designed for direct charging of electric vehicles. Compatible with CCS2 (European standard), CHAdeMO (Japanese standard), GB/T (China standard), and NACS (North American standard), covering over 99% of electric passenger vehicles, commercial vehicles, and engineering vehicles on the market.
AC output (220V/380V,10–30 kW): Used to power other equipment at the rescue site—including lighting devices, communication equipment, medical devices, power tools, and electric kettles. In disaster emergency scenarios, a single mobile charging unit can simultaneously charge an electric vehicle (DC) and supply power to an emergency command tent (AC).
Real-time positioning and scheduling: All mobile charging units are equipped with 4G/5G communication modules and GPS positioning capabilities, connecting to a cloud-based dispatch platform. Upon receiving a rescue request, the platform automatically matches the nearest unit with sufficient battery capacity and provides the operator with the optimal rescue route.
Battery remaining prediction: The system dynamically calculates the "number of executable rescue missions" based on current battery level, estimated energy consumption for rescue operations, and required power for returning to base, preventing mobile units from being unable to return due to insufficient battery capacity.
Remote firmware upgrade: All control software supports OTA remote upgrades, allowing updates to charging protocols, optimization of scheduling algorithms, and correction of software defects without returning to the factory.
Collaborate with existing road rescue service providers (such as ADAC or The AA in Europe, or regional towing companies) under the value proposition of "mobile charging instead of towing." The partnership model includes: rescue platforms paying per-service fees (€50–€100 per rescue); or our mobile charging units being stationed at partner sites, with monthly hosting fees plus a per-use revenue share.
Cost-Benefit Analysis: A 50 kWh mobile charging unit can perform 4–6 rescue operations per day, with a service fee of €80 per operation and daily revenue ranging from €320 to €480. After deducting operating costs, the payback period for each unit is approximately 12–18 months.
During peak travel seasons (summer coastal routes and winter ski routes), mobile charging units are deployed at service areas to complement fixed charging stations. Users pay for charging services by scanning QR codes, with operators charging between €0.50 and €0.80 per kWh (an additional €0.15–0.25 per kWh "mobile convenience premium" applied on top of the fixed station rates).
Cost-Benefit Analysis: During the peak season (approximately 120 days), each device charges an average of 200 kWh per day, generating daily revenue of €100–€160. When combined with road rescue income during the off-season, the overall investment payback period is approximately 18–24 months.
Logistics companies, bus companies, and shared mobility platforms procure mobile charging units as internal assets for the following purposes:
Provide rapid energy replenishment for vehicles with low battery levels to avoid disrupting operational plans
Provide backup charging during faults or maintenance of fixed charging stations
Provide a charging operation training platform for newly hired drivers
Value Assessment: A single mobile charging unit can mitigate operational losses incurred by fleet suspensions due to power shortages. Conservative estimates indicate each unit prevents annual operational costs of ¥50,000–100,000 (based on a medium-sized fleet of 50 vehicles).
Government emergency management departments, the Red Cross, and large enterprises procure mobile charging units as emergency reserve assets. These units can be used for internal vehicle charging and employee services during normal operations, and immediately converted into emergency power sources during disasters. This model has been successfully implemented in several European countries—for example, a German federal state purchased 20 mobile energy storage charging units, which provided power support to over 300 rescue vehicles and emergency equipment during the 2024 floods.
