CHARGE ALGORITHMS:
All our chargers have microprocessor/Firmware-based charge algorithm. So, if you order your charger
for Lead Acid, you can always change it later, say to Lithium, by just replacing a chip.
The standard algorithm offered for Lead-Acid battery is as follows:
RAMP PHASE: The charger starts by ramping from 0 Amp to its maximum current.
BULK PHASE: It feeds maximum current, to battery, until its voltage reaches ABSORB value.
ABSORB PHASE: Keeps the battery voltage at ABSORB value (about 2.45 per cell). As battery is
charged, current drops. When current reaches 3A, it goes to PULSED EQUALIZATION.
PULSED EQUALIZATION: for 3 minutes, 2.55V / cell is applied for 30 sec and removed for 30 sec.
COMPETE PHASE: It stops or goes to FLOAT Mode (specify which) where 2.1V/ cell is applied.

2. Solar EV Chargers:
Install solar panels, on your car, truck, garage roof or a pole. Then, this charger will change
its voltage, and controls its current, to charge your EV; ether producing 115VA to use the
vehicle's own charger or 48 to 144V ( specify) to charge EV battery directly.
A station battery can be added too. Then, it collects day-time sun energy and charges EV at
night or cloudy days. This way, you can also charge your EV faster than directly from sun.
Our popular 48V scooter model uses 12V 80W panel (see the Charge station Section of this
website). It has a 12V 100AH station battery.
Our standard Electric Car model has a 1KW MPPT solar charger which takes 48V- 200 to
1KW solar panel, and 168V-400AH Station Battery. It can charge a 144V EV with 10A.
More Details in Solar Charge Station section of our website.
Technical Specifications of 1KW:
Input : nominal 48V panel voltages (48 to 70V) up to 20A
Output: 115VAC - 1.6KW (AC model) or steered EV voltage (144 to 180V) to
charge a 144V EV at 10A
Protections: Fuses at input and output, Over-voltage shut-down and
over-heat shutdown
Connections: Internal terminal blocks for input and cord for EV
Indications: Local or Remote LED alarms and Status, Ammeter for Station
and EV charge currents.
Controls: Remote commanded Relay to turn EV charge ON or OFF
- Station Battery to Charge EV at night and cloudy days.
- Solar Panel or Windmill charges the station battery
- Produces 115VAC ( or 230VAC), from Station Battery, to charge an EV
by its own charger or Produces DC to charge EV battery directly - Models for Electric Car, Electric Boat or Scooters
- Microprocessor for proper charge algorithm
- Models from 120W to 3KW output Power
