Operating requirements

System should be placed vertically upward during operation

As a high voltage device, the system shall not be used, disassembled or maintained by non -professionals.

When connecting the system to external circuit, the circuit switch must be cut off first, otherwise there would be danger of high-voltage shock

Before operating the system, connect communication cables to vehicle system correctly, and make sure the positive and negative polarity of power supply and load

Short-circuit and reverse connection of the system is strictly prohibited, cut off circuit and take safety measures once such cases happen

Check each parameter on the human-computer interface(HMI) to ensure the voltage of each cell is between 2.80~4.05V and the maximum voltage difference shouldn’t be larger than 200mV

The system case is filled with nitrogen to positive pressure, when the pressure in the case is<0.01bar, nitrogen should be refilled until the pressure goes to 0.3~0.4bar

Please stop charging when peculiar smell or abnormal noise is found during charging the system

Abandoning used capacitor is strictly prohibited, please discharge capacitor to 0V before recycling

Storage and transportation requirements

Ambient temperature: -30~65℃

Relative humidity: 0~95%

Ambient pressure: 86~106kPa

System should be placed vertically upward during storage and transportation

Keep power interfaces protected in order to prevent collision, which may cause short circuit during the process of storage and transportation

System must be charged to rated voltage before long term storage and transportation. Check cell voltage difference every 45 days, when cell voltage difference is<200mV and >50mV, balance system should be activated until the cell voltage difference drops to ≤40mV, when cell voltage difference is>200mV, child node or capacitor should be checked, replace the bad child node or cell if necessary

When system is kept unused for longer than 1 year, it should be tested by Aowei before using.

Avoid contacting corrosive materials, keep away heat sources and fire sources

Prevent violent vibration, collision or crush during the process of transportation

Prevent exposing in the sun and rain, and keep dry and ventilated during transportation

The system can be transported by cars, trains, ships, etc
