AC charger with boost feature Jump starter with lithium battery. Some AC battery chargers have a boost, engine start, or engine assist feature. Despite being able to assist in jump starting a dead vehicle battery, these types of battery chargers perform their task over a longer period of time, rather than an instantaneous boost.
The boost charger CC/CV charging algorithm is a further development of the constant current/constant voltage algorithms. Instead of using the constant voltage and current in the entire charging period, it boosts the charging efficiency through maximizing voltage in the first period, with the battery reaching approximately 30% of its nominal ...
The first of these systems to be revealed was the Flybrid. [4] This system weighs 24 kg (53 lbs) and has an energy capacity of 400 kJ after allowing for internal losses. A maximum power boost of 60 kW (81.6 PS, 80.4 HP) for 6.67 seconds is available.
But, generally speaking, if you use the car’s own navigation system to find a charge station, it will start to precondition its battery once you’re around 30 to 45 minutes away from the charger.
A 48 V system can provide more power, improve energy recuperation, [7] and allow up to an 85% decrease in cable mass. [10]12-volt systems can provide only 3.5 kilowatts, while a 48 V power could achieve 15 to 20 kW or even 50 kW. 48 volts is below the level that is considered safe in dry conditions without special protective measures.

Every psi of boost uses 6-7bhp from its power source, but many such kits use 12-volt battery system instead of 48-volt battery system used in the chargers for production vehicles, so the gain from a 12-volt kit is effectively cancelled. [3]
