1. Safety Precautions
During product installation, operation, and maintenance, electrical safety regulations and related
operating procedures must be observed, otherwise it may cause personal injury or product damage.
The safety precautions mentioned in the manual are only a supplement to the safety regulations.
The manufacturer does not assume any responsibility caused by violation of general safety
operation requirements or violation of safety standards for design, production and use of
equipment.
Please ensure the following before use:
➢Lithium batteries should be kept away from water, dust and pollution sources. Please install the
lithium battery in a well-ventilated environment.
➢Ensure that the positive (+) and negative (-) polarities of the lithium battery and the charging
and discharging equipment are correctly connected.
➢Ensure that all cables have good electrical characteristics and suitable wire diameter.
➢Avoid direct sunlight.
➢Do not connect the DC output with lithium batteries in parallel.
➢Do not short-circuit the lithium battery output interface.
Especially keep these rules:
➢Do not expose the Energy Hub to water or fire for risk of electrocution or explosion.
➢Do not push any objects into the hub or crush the unit in any way.
➢Do not open the Hub without prior permission.
➢During use, when the system needs to be moved or rewired, the power must be completely cut
off and the system must be completely shut down, otherwise there will be a risk of electric
shock.
➢In order to avoid fire and electric shock, it is forbidden to use damaged or too small cables.
General actions to be taken by the user if these dangers occur:
➢When the electrolyte of the lithium battery leaks, it is necessary to prevent the electrolyte from
contacting the skin or eyes; if it has been in contact, please wash it with water in time and seek
medical attention as soon as possible.
➢When encountering a fire, please use a dry powder fire extinguisher to extinguish the fire. The
use of a liquid fire extinguisher may cause secondary hazards.
Disposal or recycle
Disposal and recycling of lithium batteries should comply with local, state, and
federal laws and regulations. Mixed treatment with other (industrial) waste is
prohibited.

2. Product Introduction
Energy Hub is a lithium battery energy storage system with built-in in-vehicle charging, and can be
connected to an inverter, DC load, MEH display unit, WIFI/GPRS module, etc. The main features
are as follows:
➢Lightweight and Compact
Unlike traditional systems consisted of lead acid batteries and individual products, Energy Hub
features integrated design with high performance lithium battery which keeps the overall weight
below 20kg and meantime with a much smaller footprint. Designed with concept of plug and play,
the installation time of Energy Hub can be dramatically reduced.
➢Professional Lithium Battery
Energy Hub adopts lithium battery technology featuring 5 times more life expectancy compared with
lead acid battery. To assure the best performance, sophisticated BMS has been designed
integrating many unique features.
⚫High discharge current
⚫Built in precise shunt for battery SoC calculation
⚫Built in heating element for lithium battery, will automatically heat the lithium battery cell at low
temperature to assure the safe charging during winter, but only upon external charging
resources detected
⚫Built in energy management to protect the battery from deep discharge
➢Booster Charger
With powerful Euro 6 compatible booster charger built in, battery can fully charge the battery within
2 hours while driving to assure the energy.
➢Mobile and Cloud monitoring
User can see multiple data via MEH panel. The built in Bluetooth of MEH panel supports app from
mobile phone as well. With additional 4G data stick, fleet management can be achieved remotely
via cloud.
