What is the difference between CR2025 battery series circuit and CR2025 battery parallel circuit?
CR2025 battery series circuit:
1. The current in the series circuit is equal everywhere: I=I1=I2=I3=……=In
2. The total voltage of the series circuit is equal to the sum of the voltages everywhere: U total = U1+U2+U3+……+Un
3. The equivalent resistance of the series resistors is equal to the sum of each resistance: R total = R1+R2+R3+……+Rn
4. The total power of the series circuit is equal to the sum of the powers: P total =P1+P2+P3+……+Pn
CR2025 battery parallel circuit:
1. The components in the combination have the same voltage: U1=U2=U3=……=Un
2. The current flowing into the combined endpoint is equal to the sum of the current flowing through several components: I total = I1+I2+I3+……+In
3. The reciprocal of the equivalent resistance of parallel resistors is equal to the sum of the reciprocals of each resistance: 1/R=1/R1+1/R2+1/R3+……+1/Rn;
4. The total power of the parallel circuit is equal to the sum of the powers: P total = P1+P2+P3+……+Pn;
What is the difference between parallel and series connection of CR2025 battery packs?
With the development of new energy, everyone will equip their equipment with one or more sets of UPS power supplies during construction. UPS, an uninterruptible power supply, is a constant power supply that contains an energy storage device and uses an inverter as its main component. Voltage constant frequency uninterruptible power supply. In applications, in order to improve operational reliability, several UPSs are often required to be connected redundantly. There are two ways of redundant connection of UPSs: series connection and parallel connection.
UPS batteries are connected in parallel: the positive side of the battery is connected to the positive side, the negative side is connected to the negative side, and they are connected side by side. The voltage remains unchanged, the capacity increases, and the corresponding current also increases, which plays a role in capacity expansion. But not all UPS can be connected in parallel. The output impedance of all batteries is different. Direct parallel connection is dangerous. It is best to use specially designed parallel batteries.
