➡ Electric vehicles (EVs) are awesome, but charging them can take a while, especially at home with a regular charger. That’s where the mini DC charger comes in! Designed for fast and efficient charging, the mini DC charger can easily be mounted on your wall.

👉 When it comes to EV charging, we have two types of chargers: AC and DC chargers. AC chargers are regular chargers that are slower and typically used at home. It has a lower output power, ranging from 7kW for single-phase up to 11kW/22kW for three-phase. DC chargers or fast chargers are commonly found at public charging stations. They have higher power outputs which usually exceed 60kW.

⚡ The mini DC charger is right in between these two chargers in terms of charging speed. It charges faster than AC chargers, but not as fast as DC chargers. It typically operates within 20-40kW range.

💡 So, why would you want a mini DC charger?

⏩ One simple reason: faster charging at home! As EV battery capacities increase (some even go up to 100kWh!), it takes longer to charge them with a regular 7kW household AC charger. A mini DC charger can charge your car much faster at home.

⏩ AC chargers usually need an onboard converter (OBC) to convert AC power to DC power. On the other hand, mini DC chargers are able to increase charging power without the need for OBC by incorporating the converter within the charger itself. While mini DC chargers may be smaller in size compared to high-power alternatives, they still offer faster charging rates.

❓ What’s next for mini DC chargers?

⏩ Mini DC chargers are also a good fit for some public places, like shopping malls. They’re not super-fast, but that’s okay because most people usually spend more than one hour in shopping malls. This means that installing high-power DC fast chargers may not be necessary as mallgoers won’t need a full charge within that timeframe. Using mini DC chargers in shopping malls may extend the charging times slightly but it still ensures that EVs are fully charged by the time the users are finished shopping. As a result, this frees up space and keeps the electricity grid happy.

✖ In the future, mini DC chargers could even change how EVs are built! With both AC and DC charging options currently in play, vehicles are equipped with OBCs for AC charging. However, transitioning to mini DC charging allows the removal of the AC charging interface and OBC, simplifying the vehicle design of EVs. It also makes EVs more reliable given the higher failure rate of OBCs. Lastly, removing OBCs also allows for cost savings in terms of materials and after-sales service.

In my previous article, I discussed the applications of mobile emergency energy storage vehicles. Now, let’s dive deeper into the internal structure of these mobile battery vehicles. They consist of the following key components:

1. Lithium Iron Phosphate (LFP) Battery System

The LFP Battery System is the core of mobile battery vehicles. It is comprised of multiple battery packs, a high-voltage main control box, and a Power Conversion Systems (PCS) set.

The energy storage component used Lithium Iron Phosphate which has the following characteristics: high energy density, long cycle life, and large charging and discharging rates. Aside from that, it is also safe and eco-friendly. This battery pack is secured into a battery holder using screws and plywood at the front and back.

Another component of the battery system is the BMS or Battery Management System, which is used to monitor the health of energy storage batteries. It is used to intelligently manage and maintain each battery unit, preventing the battery from overcharging and over-discharging which helps extend the battery’s service life. You’ll usually find the BMS as a circuit board or a hardware box.

Finally, another essential component is the Power Conversion Systems (PCS) set. In addition to the bidirectional inverter function, the PCS set can also support the grid, ensuring the stable operation of the grid system. It provides resistance to short-term impact, a smooth power supply, energy storage, and peak shaving.

LFP Battery Systems have many applications including electric vehicles (EVs), peak shaving, frequency modulation, emergency backup power supply, and more.

2. Uninterruptible Power Supply (UPS)

An Uninterruptible Power Supply (UPS) is a system device that connects the battery (lead-acid maintenance-free batteries) to the host and converts DC power into commercial power through module circuits such as the host inverter. UPS power serves as a backup power supply during equipment startup.

3. Gyroscope

A gyroscope is a high-performance 3D motion attitude measurement system based on MEMS technology. It has motion sensors such as a three-axis gyroscope and a two-axis accelerometer. It integrates these high-performance sensors and uses a self-developed attitude dynamics core algorithm engine. Combined with a Kalman filter fusion algorithm, a gyroscope provides high-precision, highly dynamic, and real-time compensated three-axis attitude angles—offering flexible selection and configuration of various data types to meet different application scenarios.

4. Infrared Camera

An infrared temperature sensor is essential for the interior monitoring system. This sensor connects to the equipment host through RS485 communication, enabling real-time monitoring of the internal environment.

5. Heat Dissipation System

The primary equipment in the electrical room, the PCS system, utilizes direct exhaust cooling to maintain proper temperature. The battery compartment uses industrial air conditioning to control the temperature.

6. Fire Protection System

Safety is very important, so these vehicles come with special fire extinguishers that use heptafluoropropane (HFC-227ea) gas. Heptafluoropropane is a widely used product known for environmental protection, safety, and economic costs. Heptafluoropropane fire extinguishers are colorless, odorless, and don’t conduct electricity. They are also not very toxic and don’t create any extra pollution.

Its fire-extinguishing mechanism is similar to methylalkane series fire-extinguishing agents. During combustion, the fire-extinguishing agent decomposes thermally, generating fluorine-containing free radicals. These free radicals (H+, OH-, and O2-) react in the gas phase to suppress the chemical reaction during combustion, effectively extinguishing the fire.

7. EMS system

The core Energy Management System, or EMS, is another critical component. The EMS is directly responsible for the control strategy of the energy storage system. This control strategy significantly impacts the battery’s decay rate and cycle life, ultimately affecting the economic viability of the energy storage system. The EMS also monitors for system abnormalities during operation to provide timely and rapid troubleshooting, ensuring equipment protection and overall safety.

These are the essential parts that make up a mobile emergency battery vehicle. Optimal performance and safety rely on the scientific integration of these various systems. If you’re interested in such a solution, send us a message at Charge Ninja.

Big news from the EV world in Germany! The Federal Ministry for Economic Affairs and Climate Protection (BMWK) has officially closed the chapter on the electric vehicle subsidy program, effective December 16. As of Monday (December 18), no new applications for EV subsidies are being accepted.

Why the Change?
Budget constraints have driven this decision responding to a recent ruling by Germany’s Federal Constitutional Court. They nixed the use of 60 billion euros initially allocated for an epidemic response fund, creating a 17 billion euro gap in the 2024 federal budget. Consequently, subsidies for electric vehicles, solar energy, and more got the budget cut axe.

The Impact So Far:
Reports reveal Germany invested a whopping 10 billion euros in subsidies for approximately 2.1 million electric vehicles since 2016. While the subsidy program was set to run until 2024, it has been halted due to recent budget constraints. Despite this pause, Germany remains committed to getting 15 million electric vehicles on the road by 2030.
