Votronic charging converter, B2B battery-to-battery charger VCC 1212-70

Product description
Technical details

High charging power evenfor shortdistances orfull charging for longer journeys.

Increases/decreases the voltage to the necessary level to be able to charge the on-board battery precisely with the optimum charging characteristic curve.

Fully compensates for line losses and voltage fluctuations of the dynamo, as they occur to a considerable extent e.g. inEuro 6 vehicles (intelligent alternators).The dynamo fully compensates for line losses and voltage fluctuations of the alternator, which occur to a considerable extent in Euro6 vehicles(intelligent alternators).

Compact design, low weight (high-frequency switch mode technology) and power components with strong dimensions for safe operation.

Significantly betterenergy balance of theon-board battery without intervention in the starter circuit

12 V consumers supplied with power are protected against overvoltage and voltage fluctuations.

The charging voltage is free of peaks and regulated in such a way that overcharging of the batteries is ruled out.

Fully automatic operation:The unit is permanently connected to the batteries and is automatically activated by the vehicle's running dynamo. When the engine is not running, the batteries are not discharged.

Parallel and buffer operation: In case of simultaneous consumption, the battery continues to be charged or kept full. The unit automatically calculates and monitors the adjustment of the charging times.

Monitoring-free charging: Multiple protection against overload, overheating, overvoltage, short-circuit, malfunction and battery back-discharge by electronic cut-off up to complete disconnection of unit and battery.

Built-in on-board power supply filter: Problem-free parallel operation with other charging sources (EBL, chargers, motor and fuel generators, solar systems) on one battery.

Charging cable compensation: Voltage losses on the charging cables are automatically compensated.

Connection for battery temperature sensor(included): For lead batteries (acid, gel, AGM), the charging voltage is automatically adapted to the battery temperature, resulting in better full charging of the weaker battery in cold weather and avoiding unnecessary battery gassing in summer temperatures.

LiFePO4 batteries: Battery protection at high and especially at low temperatures < 0°C.

Charging aid for deeply discharged lead batteries: Gentle pre-charging of the (lead-acid, -gel, -AGM) battery up to 8 V, then powerful support of the battery with consumers possibly still switched on.

programmes1

"Gel": Charging programme for gel batteries, characteristic IU1oU2oU3
Adapted to sealed, gas-tight gel/dryfit batteries with fixed electrolyte, which generally require a higher charging voltage level and longer U1 holding times in order to achieve short charging times with particularly high capacity storage and to avoid long-term battery "starvation".

2"AGM": Charging programme for AGM/fleece batteries, characteristic IU1oU2oU3
Intended for charging sealed, gas-tight AGM (Absorbent-Glass-Mat) batteries in lead-fleece technology, which require a particularly high U1 level with coordinated holding times for full charging and then a moderate U2 level for charge retention (plate and round cell technology).

4 "UNIVERSAL": Charging programme for lead-acid/wet/AGM batteries, characteristic IU1oU2oU3
Universal programme for charging and charge retention of acid batteries in vehicles (mixed mobile/stationary). With medium U1 level, still offers short charging times, good charging factor and good acid mixing for open and closed, low-maintenance, maintenance-free standard, drive, lighting, solar and heavy-duty batteries, as well as AGM batteries with normal U1 level.

Li "LiFePO4": Charging programme for lithium batteries, characteristic IU1oU2oU3
Charging programme adapted to lithium LiFePO4 batteries with their own BMS and prescribed or built-in protective circuitry.
