Therefore:
1. Do not open damaged batteries;
2. Do not damage the battery again (shock, fall, trample, etc.);
3. Keep damaged batteries away from water (except to prevent an energy
storage system from catching fire);
4. Do not expose the damaged battery to the sun to prevent internal heating
of the battery.
Electrical hazard: The reason of fire and explosion accidents in lithium batteries
is battery explosion. Here are the main factors of battery explosion:
1. Short circuit of battery. Short circuit will generate high heat inside battery,
resulting in partial electrolyte gasification, which will stretches the battery
shell. The temperature reaching ignition point of internal material will lead
to explosive combustion.
2. Overcharge of battery. Overcharge of battery may precipitate lithium metal.
If the shell is broken, it will come into direct contact with the air, resulting
in combustion. The electrolyte will be ignited at the same time, resulting in
strong flame, rapid expansion of gas and explosion.
Chapter 2 - Product Introduction
2.1 Scope of application
PSI-J3000-RF inverter is used in energy storage retrofits and is a new type of AC
coupled energy storage system. The built-in lithium battery inside the device can be
expanded in capacity according to user demands, and the modular design of the
slave device makes it easy to install wiring.
In daytime, solar power supports the loads first while the surplus power will be
stored on system, to improve self-consumption rate.
In peak power price hours, power from PSI-J3000-RF supports the loads; while in
valley power price hours, the device is charged by the grid. Finally a balance could
be realized. In case of grid fault, system will make sure no outage in the loads,
achieving UPS function.
