An Energy Storage Solution consists of one or more Energy
Storage Modules.
An Energy Storage Module (ESM) is similar to a Capacitor Module
in that it stores energy in a capacitor bank. The important
differences are:
- An ESM will generally have a lot more capacitance (20mF or
more) than a typical Capacitor Module, and therefore can store a
lot more energy
- Has its own power transistors to control energy flow to and
from the DC Bus
- Operates under its own voltage range, separate from the shared
DC Bus of the servo system
- Can also add Expansion Modules (EM) storage capcitors to
further increase energy storage
- Other forms of energy storage include Double Layer Capacitors
(DLC) and batteries
- Energy Storage (xES)
- Similar to a capacitor module, stores braking energy, that can
be used later in the cycle
- Add EMs for additional energy storage
- Multiple EMs are connected in parrallel
- Supply Power (xEV)
- Provides backup power when mains supply is not available
- Add EMs for additional energy storage
- Multiple EMs are connected in parrallel
- Energy Storage and Supply (xEK)
- Performs both functions of energy storage and backup power
- The amount of energy storage reserved for backup power is
configurable
- Add EMs for additional energy storage
- Multiple EMs are connected in parrallel
- Storage Manager (xSM)
- Performs both functions of energy storage and backup power
- The amount of energy storage reserved for backup power is
configurable
- Supports various extended energy storage modules including EMs,
DLCs, batteries
- Multiple DLCs are connected in series
DLCs can be connected in series or parallel. Consider the
solution
01x DSM4.0-60-xx-xx 04x DLC-2-10-90.
The Model name uses the following nomenclature: 1 DSM, connected to
4 parallel banks of DLCs. Each bank contains 2 DLCs in series. Each
DLC has 10F capacity and a maximum voltage of 90V. Overall there
are 8 storage modules with 20F in total and a maximum voltage of
2 x 90V = 180V
