An intelligent charger may monitor the battery's voltage, temperature or charge time to determine the optimum charge current or terminate charging. For Ni–Cd and Ni–MH batteries , the voltage of the battery increases slowly during the charging process, until the battery is fully charged.
The RaceBird is an all-electric hydrofoil boat. It is 24 feet long, with aluminum hydrofoils which raise the boat when reaching a speed of 17 knots. The 200-hp electric motor can reach a power output of 150 kW and has a battery capacity of 35 kWh. It can reach a top speed of 50 knots (58 MPH/93 KPH).
India's First Solar Ferry, a 75-passenger boat, that is powered by sun and grid charging with lithium batteries, began service in 2017. [31] Based on the predictions of consumption the payback time is 3 years. [32] [33] [34] Some ferries can charge their onboard batteries while docked by using a pantograph. [35]
Battery manufacturers' technical notes often refer to voltage per cell (VPC) for the individual cells that make up the battery. For example, to charge a 12 V lead-acid battery (containing 6 cells of 2 V each) at 2.3 VPC requires a voltage of 13.8 V across the battery's terminals.
A series charge controller or series regulator disables further current flow into batteries when they are full. A shunt charge controller or shunt regulator diverts excess electricity to an auxiliary or "shunt" load, such as an electric water heater, when batteries are full. [7] Simple charge controllers stop charging a battery when they exceed ...
IUoU battery charging is a three-stage charging procedure for lead–acid batteries. A lead–acid battery's nominal voltage is 2.2 V for each cell. For a single cell, the voltage can range from 1.8 V loaded at full discharge, to 2.10 V in an open circuit at full charge.
