According to the technical solution of 100KWH energy storage system released by BSLBATT, the system mainly consists of energy storage converter PCS and lithium iron phosphate battery pack. Among them, the PCS is a 50kW off-grid bidirectional energy storage converter, which is connected to the grid through a 0.4KV AC bus to realize the bidirectional flow of energy. The battery pack consists of 10 51.2V 205Ah batteries connected in series, with a total voltage of 512V and a capacity of 205Ah. This configuration not only provides sufficient energy storage capacity, but also ensures the stability and safety of the system.

1. High energy density: the energy density of lead to lithium batteries is much higher than that of lead-acid batteries, which means that lithium batteries are able to store more electricity under the same volume or weight. 2. Long life: the cycle life of lead-converted lithium batteries is much longer, usually up to 1200-2000 times, while the cycle life of lead-acid batteries is only 500-900 times. 3. 3. Lightweight: The small size and light weight of lead-converted lithium batteries make them suitable for use in mobile equipment and electric vehicles, which reduces the burden on the equipment and improves the convenience of carrying. 4. High charging and discharging efficiency: lead to lithium batteries in the charging and discharging process of the energy loss is smaller, can be more effective use of electric energy.

Energy storage, simply put, is the process of storing excess energy until it is needed and then taking it out and using it. It's like keeping food in the refrigerator and taking it out to eat when we're hungry.

Increased policy support: governments have introduced policies to encourage the development of energy storage. For example, China issued the ‘on accelerating the development of new energy storage guidance’, a clear development of new energy storage in the coming period of time the objectives and tasks and key work. Strong market demand: With the rapid growth of new energy generation, the demand for energy storage is becoming increasingly urgent. The role of energy storage system in the power system is becoming more and more prominent, not only to improve the stability of the power system, but also to promote new energy consumption.

Lead-acid batteries, as the ‘big brother’ of the battery industry, has a history of more than 150 years. It has dominated the energy storage market for a long time due to its low cost, mature technology and simple maintenance. Whether it is a car starter battery, an electric bicycle, or a backup power supply, lead-acid batteries can be found everywhere.

Energy storage is simply the storage of excess energy so that it can be released when needed. Just like when we charge our mobile phones, electricity is stored in a battery to be used when the battery is dead. However, the scale and application of energy storage is much broader than mobile phone batteries.
