The stable, efficient and low-cost operation of the grid is the basis for the economic development. The amount of power generation and power consumption must be balanced in real time. Traditionally the grid needs to quickly detect the electrical load of users in real time and adjust the power generation to maintain the balance between electrical supply and demand, which brings
The efficiency of a battery cell is the energy released during discharging divided by the energy stored during charging. The efficiency of lithium-ion batteries is very high, usually above 95%. High efficiency, together with high specific power, high energy density, and low self-discharging rates, have made lithium-ion the mainstream of today''s battery technology.
