Abstract
A battery with a battery management system is capable of charging the battery with recaptured energy from an energy regeneration device. The battery management system charges the battery with the energy regeneration device if the output voltage from the energy regeneration device is larger than the charging voltage of the battery.
Claims14
A method for recharging a battery in a vehicle equipped with a battery management system and connected to an energy regeneration device, the method comprising:
- receiving an output voltage from the energy regeneration device;
- receiving an indicator that the vehicle is in motion;
- comparing the output voltage from the energy regeneration device with a charging voltage for the battery;
- and
- if the output voltage is larger than the charging voltage and the motion indicator indicates motion, then charging the battery with the energy regeneration device.
A vehicle with a battery with a management system connected to an energy regeneration device, the battery in the vehicle comprising:
- a plurality of battery cells;
- a charger connected to the plurality of battery cells;
- and
- a controller connected to the plurality of the battery cells and to the charger,
- wherein
- the controller receives an indicator that the vehicle is in motion, and
- the controller enables a connection between the energy regeneration device and the charger to charge the plurality of battery cells if the indictor indicates motion and an output voltage from the energy regeneration device is larger than a charging voltage for the plurality of battery cells.
A battery management system for a vehicle with an energy regeneration device and a battery, the battery management system comprising:
- a storage unit with a plurality of machine-readable instructions;
- a controller retrieving the plurality of machine-readable instructions, wherein the machine-readable instructions executed by the controller causes the battery management system to
- receive an output voltage from the energy regeneration device;
- receive an indicator from the vehicle;
- compare the output voltage from the energy regeneration device with a charging voltage for the battery;
- and
- if the output voltage is larger than the charging voltage and the indicator indicates the vehicle is in motion, then charge the battery with the energy regeneration device.
