Home lithium storage battery

Home lithium storage battery systems have recently improved in two substantial ways, and the first big improvement is in the batteries themselves. Lithium-ion

10kwh energy storage system kit

batteries on the market today are much more robust and functional than the lead-acid batteries we have relied on in the past. Discharging a lead-acid battery beyond 50% capacity can damage the battery and reduce its future storage capacity. Also, lead-acid batteries require periodic maintenance throughout their

relatively short lifespan and lead poses human health risks.

The latest lithium ion batteries require little maintenance, offer a longer lifespan, and often, the ability to be fully discharged without harming the battery. No longer being limited to using only half of the stored power in a battery effectively doubles their capacity.

The second big improvement is the advent of ‘smart’ battery controls. Battery systems have always required a charge controller to make sure the batteries are not overcharged or discharged too deeply; the latest batteries on the market include Smart EMS Energy Managment systems. It is certrel control to communicate with all devices inlcude PCS, solar controler, Battery BMS system and On grid power. This is very important when using battery systems with solar arrays, because the inverters in a solar array system require power to begin making power, regardless of whether they are tied to the grid or not.

Why need home electricity battery storage?

  • Peak-Shaving Function
    In one sense, store electric energy when it is surplus and output stored electric energy after inverting when it is insufficient. This is the basic function of storage system–Peak-shaving function.
  • Independent inverting function in emergency
    When the power grid loses electric energy, storage system will be used as independent inverter power supply and provide AC electric power for important load constantly to ensure user’s requirement.
  • Accepting Debug Command From Power Grid Flexibly
    Storage system will exchange information with Remote Terminal Units (RTU) of power grid and Supervisory Control And Data Acquisition (SCADA) flexibly and conveniently, it will accept dispatch from automatic dispatch monitoring system of electric grid, to realize telesignalling, telemeter, remote control and remote transfer. The whole process will abide by MODBUS RTU. The communication media maybe wireless or wired.
  • Dynamic, static power grid support and reactive power compensation

Storage system will achieve kinds of functions according to power grid dispatch command, which includes items as follows:

  1. Provide needed active power for power grid;
  2. Provide needed reactive power for power grid;
  3. Realize low voltage cross, and enhance the stability of power grid.

How much storage does my home need

Just like solar-only systems, the size of your rechargeable solar battery system is determined by your unique energy needs and habits. Factors such as the amount of electricity you use at home and the devices and appliances you want to back up will play a key role as you select the right battery storage solution for you. Normally, if the solar power just for illumination, You will need a less then 5Kwh home battery energy system. If there is a air-condition, or other electric powered stove. You probebely need at least 5Kwh or 10kwh more.

OSM Residential Energy Storage Systems (ESS)

OSM Residential Storage Solutions (ESS) offer a wide variety of products to create and manage resilient energy infrastructures at an optimal cost. ESS offers two primary use cases. The first is creating utility-independent, solar-powered homes (residential ESS). On a larger scale, the second use case is utility supplementing generated power during periods of high demand (utility-scale ESS).

Older generation residential solar energy systems are tied to the utility power grid via inverters, which convert power from solar panels to AC electrical power during daylight hours. Marketable excess power might be sold back to utility companies. However, during the hours of darkness, the end-user is relying on the utility’s electricity supply. Utility companies are aware of these limitations and adjust their pricing models accordingly. Residential customers pay based on “time-of-use” rates, which are higher when solar power is not available.

Behind-the-meter ESS is utilized at this point. The electricity that is collected via solar panels charges batteries, the energy is then stored. When using these batteries with an inverter, the demand for AC power can be fulfilled at any time.

BATTERY MANAGEMENT IN ESS

In ESS, a battery management system fulfills two main functions, namely battery protection and battery monitoring.

Battery Protection

Detecting a variety of fault conditions and protecting the battery from damage during the charging and discharging process is the main purpose and functionality of a BMS. Operating a battery outside of its specifications causes damage to the battery cells and leads to battery failure, producing maintenance efforts, and significant cost impact. Batteries must be closely monitored during charging and discharging to avoid these negative effects.

Protection must be provided against:

  1. Overvoltage/undervoltage
  2. Inrush current
  3. Reverse currents
  4. Short circuits

Those designing with OSM’s solutions will benefit from:

  • Wider SOAs
  • Short-circuit protection with higher peak current rates
  • Turn-on and turn-off solutions tailored to application requirements
  • Cost-efficiency resulting from a reduced BOM count and more effective parallelization solutions

Battery Monitoring

A battery must be monitored systematically, to protect it. The battery management system is in charge of monitoring each of the cells in a battery pack and ensures that they are operated within the safe operating range. Various parameters, such as cell voltage, SOC, state of health (SOH), and the temperature, have a decisive impact on the performance, safety, and lifetime of batteries. A battery needs to be protected against possible external faults that would put the system in danger. Protecting the battery from damage during the normal function of the system (charging and discharging process) is one of the main functionalities of a BMS. Within Infineon’s product portfolio, designers will find the right devices to disconnect the battery system in case a fault is detected, thereby protecting its value. They will also help to detect system faults like overcurrents and short circuits.

Advanced Technology of Battery managment System

The battery is the core energy storage device of the system and needs to be monitored online status in real time, so the importance of BMS is self-evident. In the BMS management system, BCU real-time communicates with

  • CAN bus and BMU to get monomer voltages, cabinet temperature, insulation resistance and others
  • Current sensor to collect charge and discharge current and dynamic calculation SOC
  • Touch screen to display relevant data

The BCU calculates and analyzes all the information of the battery pack and then intelligently manages the system, communicating with the independent CAN bus and achieving the secondary protection of charge and discharge through a relay. The latter ensures an effective isolation for strong electricity and weak electricity, meets customer’s demand for diverse security control and guarantees a stable and efficient operation of the system.

BMS / BMU are the Core Technology

Li-ion cells should always be used with a protection circuit to prevent the cell from over charging or over dis-charging. Choosing the correct circuit and applying it appropriately is vital to the longevity your batteries and your own safety. OSM test each Cells and BMS/PCB/PCM before manufacturing and promise it is functional and safe.

BMS / PCB / PCM is the “heart” of Lithium battery pack. BMS (Battery Management System) is any electronic system that manages a rechargeable battery (cell or battery pack), such as by monitoring its state, calculating secondary data, reporting that data, protecting the battery, controlling its environment, and balancing it.

Outstanding Performance of BMS

There are six main objectives common to all Battery Management Systems:
● Protect the cells or the battery from damage.
● Cell balancing.
● Prolong the life of the battery.
● SOC determination.
● Incorporated functions: Data recording and communication (RS232/RS485,CAN, Bluetooth, SNMP and Ethernet).
● Maintain the battery in a state in which it can fulfil the functional requirements of the application for which it was specified.
