The LEAB DC/DC booster increases the charging voltage irrespective of the charge state of the starter battery to the required value of 28.2 V and supplies a continuous current of 8 amps (IU characteristic). If the auxiliary battery is fully charged, the output current of LEAB’s DC/DC booster automatically adapts itself and drops.
DC/DC boosters can be easily retrofitted in any vehicle.
After the engine has been started and a short maximum charging capacity, the generator control unit quickly reduces the charging voltage and the current to protect the starter battery from overload. At the same time, the charge current for the still empty power supply battery drops at the same time. In addition, the auxiliary battery is usually installed a relatively long way away from the generator, which means its cables are very long and rarely have a sufficient cross-section. Correct and complete battery charging is no longer possible.
