The portable power station is an integrated product that integrates the original bulk charger, inverter, battery pack, and battery protection board into one product, which is convenient for users to use.
1. There is no problem with the technology of portable power station
The portable power station is an integrated product, and the technology inherits the technology of the previous decentralized products, so there is no difficulty!
Now large-scale energy storage, chargers and inverters can achieve hundreds of kilowatts, and BMS battery management systems and batteries can achieve megawatt-level. Do you think these few kilowatts and several kilowatt-hours of energy storage power supply are useful? What technical difficulties?
Portable power station belongs to old wine in new bottle, so there are so many brands on the market.
2. The security of the portable power station is the difficulty
As we said above, the portable power station technology inherits the technology of the previous distributed products, and also inherits the security risks. Security is the real problem of the portable power station.
The safety application technology of portable power station is BMS battery management system + lithium battery pack, which mainly relies on the safety protection of BMS battery management system to ensure the safety of energy storage power supply. This safety application technology has been introduced from abroad and has not been improved for more than 30 years.
BMS battery management system + lithium battery is a working mechanism, not a safety mechanism. Can anyone understand?
Practice has proved that this technology can only guarantee the normal operation of ordinary energy storage power supplies, but cannot guarantee the safety of energy storage power supplies. The Tianjin outdoor mobile power explosion incident in September 2022 has given me a warning, and it also shows that this technology cannot guarantee the safety of energy storage power.
The explosion of the large-scale energy storage power station in Beijing and the explosion of Tesla’s large-scale energy storage power station all show that the BMS battery management system + lithium battery cannot guarantee the safety of the energy storage power supply. Are you better than Tesla and the others!
Most of the outdoor power supplies currently on the market are ordinary energy storage power supplies. It can be expected that in the next 3 to 5 years, with the increasing age of electronic circuits and lithium battery packs of ordinary energy storage power supplies, the products will gradually age. Fires and explosions will happen one after another.
This is not alarmist, it is caused by the lack of the safety theory of the entire common energy storage power supply and the defect of the safety mechanism. Danger will happen in the future, it will become inevitable!
3. How to make portable power station safe? This is our main direction of attack.
Portable power stations on the market now generally focus on battery capacity, output power, battery management system, and appearance. Didn't know the direction at all.
Has anyone considered how to make energy storage power safe?
If ordinary energy storage power supply is to be safe, it is necessary to develop the safety theory of current energy storage power supply, reshape the security mechanism of energy storage power supply, improve the security loopholes of energy storage power supply, and develop towards intelligence. Only "smart energy storage power supply "In order to be safe.
