Chargers

A good charger is crucial to electric vehicle performance. Early crude chargers simply slugged voltage into the batteries until the charger was turned off. This caused the batteries to gas heavily toward the end of the charge, and it shortened battery life. Later chargers used timers to taper the charge down and shut off. These were better, but still did not fully synchronize with the needs of the batteries. Modern chargers can sense the level of charge in the battery pack, and taper the charging current accordingly. The final, low-current part of the charge cycle serves to equalize the charge in all the batteries.

For low voltage conversions (up to 144 V), 110VAC input is acceptable. For higher voltage systems (up to 336 V), the 220VAC is needed. The chargers below offer a range of options.

Russco 110 V Chargers

Russco Charger

SC 18-120 Charger With Standard Footprint

The transformerless Russco Safety Electric Vehicle Battery Chargers provide onboard charging of both flooded and sealed lead acid battery systems from 84 volts to 144 volts. A buck/boost transformer is used with the charger to charger 132 volt or 144 volt systems, or to charge 84 volt or 96 volt systems faster. These chargers provide adjustable constant current to 80% charge, adjustable constant voltage, then minimum current to finish. A digital shut-off option will shut off the charger completely.

Features

External line cord & booster transformer connections
Pre-wired DC cord terminating in 50A Anderson connector
Easy front panel adjustments for AC current & DC battery voltage taper
Built-in ammeter monitors DC battery current
Ground fault interrupter
Power on indicator
AC line circuit breaker protection
DC fused output
Electronically regulated AC line current limit
Soft start up
Overtemp protection
Fan cooling
High power factor with low crest factor lowers AC line peak current while increasing line current duty cycle, reducing AC line equipment heating and lowering radio/TV interference

Options

Digital timer shut-off (optional on models SC 18-120 & SC 24-120, standard on model SC 30-120) can be set for 1/2, 1 1/4, 2 1/2, or 5 hours after 80% charge is reached.
Battery temperature cut-off reduces charger output if battery temperature reaches 122° F (50° C).
Separate buck/boost transformer (required for model SC 24-120) can be used to boost up AC line voltage for charging 132V & 144V systems, or to buck down AC line voltage for faster charging of 84V & 96V systems.
Mounting footprint options (models SC 18 120 & SC 24-120 only). Mounting flanges can be along the long or short sides of the charger, depending on which will fit better in the vehicle.
