Energy storage power supply trickle charging test

What is energy storage performance testing?

Performance testing is a critical component of safe and reliable deployment of energy storage systems on the electric power grid. Specific performance tests can be applied to individual battery cells or to integrated energy storage systems.

How long should a battery charger stay in a trickle charge?

It should stay in the trickle charge current level until the battery simulator voltage reaches a safe level (i.e. 3.2V), depend on the charger design. At this point the charger should start rapid charging with a normal current, typically about 1C. 1C is referring to the charging current being the same as the battery capacity.

What is energy storage pulsed power characterization (esppc)?

Energy Storage Pulsed Power Testing The energy storage pulsed power characterization (ESPPC) test is a system-level corollary to the HPPC test described in Section 2.1.2.2. The goal of ESPPC testing is to define the bounds of the region shown in Figure 10..

Can a battery be trickle-charged with a low voltage?

At low battery voltage (below 3.2 volts), it needs to be trickle-charged with a low current. The battery is can’t handle a higher charging current when the voltage is too low, so for safety reasons the trickle-charge current is typically one-tenth of normal.

How many charge/discharge cycles should a battery have before testing?

The battery(ies) shall have experienced no more than 5 complete charge/discharge cycles prior to testing. Testing shall be conducted with the following steps. Note that there are two discrete testing procedures provided below: an abbreviated and full test methodology.

Can battery cell performance testing be used in grid support applications?

Challenges in Energy Storage Performance Testing Battery cell performance testing is well developed for use in personal devices, automotive applications, and even backup power supply applications; however, it is not as developed for grid supportive applications.
