Introduction
The BLUESHAPE series of intelligent lithium ion battery chargers
has been specifically designed for fast and reliable charging of the
BLUESHAPE V-lock battery range. All charger models (except
CVTR1M) are capable of delivering around 4 Amps in constant
current mode making them particularly suitable to users who require
a fast turnaround from their batteries.
For the users’ convenience, the external dimensions have been kept
as compact as possible for better portability.
Properties of the CVTR2
- Elegant and robust design. Ideal for daily use
- Sophisticated electronics for accurately detecting the charging
state
- Three-colour LED indicator for individual charge-station
monitoring
- Pre-charge function for protecting heavily discharged cells
against high currents until their voltages rise to a safe level.
- Maximum compactness and space utilisation
- IPCS and CTP Features (see opposite page)
- Powerful auxiliary output at 13.8V / 110W through 4-pole XLR
- Data connector for computer connectivity and monitoring of
Blueshape batteries through special software (available as a
separate product)
Battery charging and performance features
The electronic circuitry provides a very accurate lithium ion charge
algorithm. Initially, the chargers will only apply a pre-charge current
of a few milli-amperes to batteries that are heavily discharged. This
same current enables the charger to detect the current battery state.
Once the cells inside the batteries reach a safe level, the full
(maximum) charging current is delivered until the battery reaches
almost 80% state of charge. After this, a constant voltage phase
begins with the charging current decaying slowly until full cut-off.
