Precision shunts are widely used in the BMS of power battery management systems, and precision shunts are used in almost every power train. Precision shunts are used for current sampling in battery management systems. As power battery shipments continue to rise, precision shunts are also welcoming market opportunities.
                                   According to relevant data, in November 2018, China's new energy vehicle power battery installed capacity was about 8.91GWh, an increase of 50.22% from the previous month, an increase of 28.53%; the cumulative installed capacity from January to November was about 43.53GWh. Each power battery is accompanied by a precision shunt to new energy vehicles, and the market for precision shunts will increase as the Chinese market grows.

In terms of power type, in November 2018, the installed capacity of power batteries for pure electric vehicles was about 8.38GWh, an increase of 52.71% from the previous month; the installed capacity of power supply for plug-in hybrid vehicles was about 0.53GWh, an increase of 21.8% from the previous month; The installed capacity of the power battery for fuel cell vehicles is about 0.00016GWh, a decrease of 5460.45% from the previous month.

In the new energy passenger vehicles and new energy special vehicles, the installed capacity of supporting power batteries accounted for 89.37% and 10.63%, respectively; the installed capacity of lithium iron phosphate batteries was 3.24GWh, and the installed capacity of new energy buses accounted for 63.06%, the installed capacity of new energy passenger cars and new energy special vehicles accounted for 17.54% and 19.4% respectively; the installed capacity of lithium manganese oxide batteries was 0.14GWh; the installed capacity of lithium titanate batteries was 0.12GWh.
   
These are data that reflect the rapid growth of new energy power battery growth, and the proportion of new energy vehicle market is also expanding. The use of shunts in new energy vehicles is also accompanied by an increase in the demand for power batteries. There will be more opportunities in the market for precision shunts in the next few years, and there will be more battery management systems applied to other industrial equipment.
