Container shipping has evolved into a modern, cost-efficient method of bulk cargo transportation.
Such a method features "safety, quickness, and low costs". Multimodal transportation can be conducted through comprehensive use of various mediums of transportation, such as railways, highways, waterways, and through the skies. Multimodal transportation makes "door to door" service possible.
According to an analysis of logistics industry development, multimodal transport has become a national strategy. The Ministry of Transport, National Development and Reform Commission, China Railway, and other departments have rolled out various policies to encourage and guide the development of the multimodal transport business. With constant changes in the transportation market and the improvements in container production technology, the demand for containers in the future will also be complex and diverse.
The role of container sensors
As a necessary container component, sensors play an increasingly important role in shipping. A container sensor can track logistics information in real time and indicate the real-time position, safety state, temperature, and humidity of a container. In addition, container data can be monitored in real time through a series of sensors (vibration, pressure, inclination, altitude, etc.) and transmitted back to the monitoring center via wireless network (2G/3G). Once the threshold set by the transportation management department is exceeded, the terminal will automatically transmit the problem, so that staff can resolve the issue in a timely manner. These smart containers feature the most widely adopted and mature GPRS wireless transmission technology. This ensures that, as long as the container is in a coverage zone, data can be transmitted to the monitoring center in real time. Data can also be viewed through a mobile phone application to access the status and information of containers in real time, improving management and working efficiency. The primary lithium battery, with long service life, high capacity, and pulse output capacity, can meet the power supply demands of container sensors.
Container sensor battery requirements
A container sensor is powered by a battery, which must be of extremely high energy density to extend the sensor’s standby time. At the same time, high-energy pulse currents are output with a very high/low ambient temperature, ensuring the success rate and accuracy of regional network transmission under more complex environmental conditions. In addition, the actual service life of the battery must reach that of the design’s life to meet the technical requirements of ultra-long standby time.
Therefore, the power supply of such equipment is also a key link that developers and engineers need to consider. In an application scenario requiring long service life, maintenance free and high reliability, HCB Battery can provide the most complete power supply solutions for container transportation management in the industry.
HCB container sensor power supply solutions
There are generally two operating modes for sensors in IoT containers. In mode I, uA-level current standby state is realized through internal MCU and power management (PMIC), which consumes very little power. In mode II, LPWAN networks are used to realize low power consumption, wide coverage, long service life, and low-cost system operation. LPWAN is a wireless network used in the Internet of Things (IoT), which uses low bit rates for long-distance communication (with lower power consumption than 2G wireless networks). Due to the rapid development of LPWAN, HCB has launched two series of power supply solutions for the container transportation industry according to industry application specifications:
HCB ER+ Power supply solution
The power supply solution with a combination of a lithium-thionyl chloride battery and battery container is widely used in such wireless remote network communication sensing systems as NB-IoT, LoRa and 2G/3G/4G for high capacity, large current pulse, low self-discharge rate and wide temperature range (-40°C to +85 °C).
HCB's innovative pouch cell solution
As the inventor of lithium-manganese dioxide pouch cell in China, HCB battery solution has four advantages:① very low self-discharge rate ② no passivation ③ high pulse and high power output ④ adaptation to a wide range of temperatures (-40°C to +80°C). What’s more, for users, battery size is no longer a restriction in product design. It is not necessary to sacrifice product functionality due to battery size and capacity. We will customize the battery structure and physical size according to your requirements.
