Trickle charging is the process of charging a fully charged battery at a rate equal to its self-discharge rate, enabling the battery to remain at its fully charged level. This state occurs almost exclusively when the battery is not loaded, as trickle charging will not keep a battery charged if current is being drawn by a load.
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.

Float voltage is the voltage at which a battery is maintained after being fully charged to maintain that capacity by compensating for self-discharge of the battery. [1] The voltage could be held constant for the entire duration of the cell's operation (such as in an automotive battery) or could be held for a particular phase of charging by the charger. [2]
The energy used to charge rechargeable batteries usually comes from a battery charger using AC mains electricity, although some are equipped to use a vehicle's 12-volt DC power outlet. The voltage of the source must be higher than that of the battery to force current to flow into it, but not too much higher or the battery may be damaged.
A trickle charger is typically low-current (usually between 5–1,500 mA). They are generally used to charge small capacity batteries (2–30 Ah). They are also used to maintain larger capacity batteries (> 30 Ah) in cars and boats. In larger applications, the current of the battery charger is only sufficient to provide trickle current.
In practice, it depends on the capability of the charger. The battery capacity C is expressed in Ah units, typically the C 20 value based on a 20-hour discharge time. [3] The charging current (in A units) can be written as C/t where t is a time. For example, for a battery with C = 40 Ah, a current C/10 is equal to 4 A. The charging current is a ...
MG1, an AC motor-generator having a permanent magnet rotor, [7] used as a motor when starting the ICE and as a generator (alternator) when charging the high voltage battery; MG2, an AC motor-generator, also having a permanent magnet rotor, used as the primary drive motor and as a generator (alternator), which regeneration power is directed to ...
