Cycle Charging with Generator: Cleaner Power, Less Runtime

As more projects aim to cut carbon and comply with NEA regulations, Infinity Cube’s cycle charging setup is proving to be an efficient and cleaner power solution for Singapore’s worksites.

Cycle charging refers to a setup where a generator only runs when needed to charge the battery and the Infinity Cube BESS powers the site most of the time. This drastically reduces generator runtime, fuel consumption, noise, and emissions.

How BESS Works Together with Generators

In off-grid locations or temporary projects, Infinity Cube BESS is paired with a diesel generator in a smart cycle charging setup.

The battery supplies power to the site as the main source. When its SOC drops (e.g., to 40%), the generator is triggered to start. It runs just long enough to recharge the battery to full capacity (100%) and then shuts off.

This method significantly reduces generator runtime, noise, and fuel usage compared to running the generator 24/7.

Key Characteristics:

Generator runs only when needed
Reduces wet stacking and maintenance
Ideal for remote or non-grid-connected job sites

Live Example: Real Site Data

(Data captured from EMS at a live site in Singapore using the Infinity Cube BESS.)

The generator (red line) only activates when the battery SOC drops to a low level (~40%). It fast-charges the battery for around 2 hours until it reaches 100% SOC, then shuts off. This cycle repeats only as needed.

As seen above, the Infinity Cube powers the site load for long hours without generator use. The generator only kicks in during low-SOC events, charging the battery quickly and shutting off once complete.

What’s the Benefit?

✅ Fuel & Cost Savings

Generator runtime cut by up to 70%

✅ Reduced Maintenance

Fewer generator hours = lower service costs

✅ Supports NEA Compliance

Quieter operation and fewer emissions

✅ Ideal for Sites Without Grid Access

Cycle charging is especially useful in remote areas or temporary setups.

Power Smarter with Infinity Cube + Generator

Whether you’re running a tower crane in a remote site or setting up power for a temporary facility, cycle charging offers a sustainable, proven solution. Choon Huat can deploy hybrid setups quickly across Singapore to meet your project’s energy needs.
