120 kW · DC Fast Charging · Storage-Integrated

120 kW DC. No Grid Upgrade Required.

Co-locate fast charging with the storage system and dispatch within the existing grid connection boundary. No transformer program. No civil works. Revenue starts at commissioning.

Traditional grid-first EV charging deployment — long lead time before first revenue

Grid-First Path

Upgrade Before Revenue.

Utility study → transformer program → civil works. 12–18 months before first charging revenue.

WattCision storage-integrated EV charging — fully operational from day one

WattCision Path

Commission Day. Revenue Day.

Deploy within the existing grid connection. The ESS absorbs the charge event — the meter never sees the demand spike.

Dispatch Logic

Tariff Spread → Daily Margin.

The ESS charges during low-tariff windows. EV loads are served from stored energy at peak hours — demand charges don’t reach the utility meter.

Core Intelligence Layer

Intelligent BMS AutoSync™

Cell-level balancing keeps usable capacity aligned across the bank, protecting performance, uptime, and long-horizon return.

Cell-level balance

Active balancing corrects mismatch at the source, not masked at the module.

Bankable capacity

Aligned cells preserve usable energy, response quality, and performance confidence.

Expansion-ready

New capacity joins a healthier bank with less manual balancing overhead.
